A ball gown is the most formal female attire for social occasions (such as white tie). It is traditionally a full-skirted gown reaching the floor, made of luxurious fabric, delicately and exotically trimmed. Most versions are cut off the shoulder with decollete necklines. Such gowns are typically worn with a stole (a formal shawl in expensive fabric), cape or cloak in lieu of a coat, "good" (couture or vintage) jewellery and opera-length gloves.

Standard accessories are dancing shoes and a clutch style evening bag. Where "state decorations" are to be worn, they are on a bow pinned to the chest, and married women wear a tiara if they have one. The ball gown shape has changed little since the mid-19th century. Although artificial fabrics are now sometimes used, the most common fabrics are satin, silk, taffeta and velvet with trimmings of lace, pearls, sequins, embroidery, ruffles and ruching.

A ball washer or ball shagger is a piece of equipment for cleaning dirty golf balls. Because golf balls have a dimpled surface to improve their aerodynamic properties, increasing both distance and control, and are used primarily on grassy surfaces, they tend to collect dirt and grass easily, which can adversely affect their aerodynamic characteristics. Ball washers are typically found on golf courses; on some courses, there is one at every hole.

Ball bonding is a type of wire bonding, and is the most common way to make the electrical interconnections between a chip and the outside world as part of semiconductor device fabrication.Gold or copper wire can be used, though gold is more common because its oxide is not as problematic in making a weld. If copper wire is used, nitrogen must be used as a cover gas to prevent the copper oxides from forming during the wire bonding process. Copper is also harder than gold, which makes damage to the surface of the chip more likely. However copper is cheaper than gold and has superior electrical properties, and so remains a compelling choice.Almost all modern ball bonding processes use a combination of heat, pressure, and ultrasonic energy to make a weld at each end of the wire. The wire used can be as small as 15 µm in diameter — such that several welds could fit across the width of a human hair.A person upon first seeing a ball bonder will usually compare its operation to that of a sewing machine. In fact there is a needle-like disposable tool called the capillary, through which the wire is fed. A high-voltage electric charge is applied to the wire. This melts the wire at the tip of the capillary. The tip of the wire forms into a ball because of the surface tension of the molten metal.The ball quickly solidifies, and the capillary is lowered to the surface of the chip, which is typically heated to at least 125°C. The machine then pushes down on the capillary and applies ultrasonic energy with an attached transducer. The combined heat, pressure, and ultrasonic energy create a weld between the copper or gold ball and the surface of the chip - which is usually copper or aluminum. This is the so-called ball bond that gives the process its name. (All-aluminum systems in semiconductor fabrication eliminate the "purple plague"—a brittle gold-aluminum intermetallic compound—sometimes associated with pure gold bonding wire. This property makes aluminum ideal for ultrasonic bonding.)Next the wire is passed out through the capillary and the machine moves over a few millimeters to the location that the chip needs to be wired up to (usually called the leadframe). The machine again descends to the surface, this time without making a ball so that the wire is crushed between the leadframe and the tip of the capillary. This time the surface is usually gold, palladium, or silver - but the weld is made in the same way. The resulting weld is quite different in appearance from the ball bond, and is referred to as the wedge bond, tail bond, or simply as the second bond.In the final step the machine pays out a small length of wire and tears the wire from the surface using a set of clamps. This leaves a small tail of wire hanging from the end of the capillary. The cycle then starts again with the high-voltage electric charge being applied to this tail.The process where wire is cut right after ball is formed is also called stud bumping. Stud bumping is used when stacking chips in system in package (SIP) modules.The current state-of-the-art machines (as of 2003) can repeat this cycle about 20 times per second. A modern ball bonder is fully automatic and is essentially a self-sufficient industrial robot, complete with a vision system, sensors, and complex servo systems.

Ball of Fire is a 1941 American screwball comedy film directed by Howard Hawks and starring Gary Cooper and Barbara Stanwyck. This Samuel Goldwyn Productions film (originally distributed by RKO) concerns a group of professors laboring to write an encyclopedia and their encounter with a nightclub performer who provides her own unique knowledge.The supporting cast includes Oskar Homolka, S. Z. Sakall, Henry Travers, Richard Haydn, Dana Andrews, and Dan Duryea. In 1948, the plot was recycled for a musical film, A Song Is Born, this time starring Danny Kaye and Virginia Mayo. The film is also known as The Professor and the Burlesque Queen. In 2016, the film was deemed "culturally, historically, or aesthetically significant" by the United States Library of Congress, and selected for preservation in its National Film Registry.

A ball dress is a uniform worn to balls. They often come in various colors. The top is generally a jacket with epaulettes and the trousers are formal trousers in a solid color. Shoes are often dress boots. Short evening gloves may or may not be worn. The length of the jacket may be thigh-length or have tapering tails at the back. White tie is generally worn to the most formal occasions, but there are times when males attending such occasions opt for ball dress.

A ball chain is a type of chain consisting of small sheet metal balls connected via short lengths of wire.The balls are hollow and have two small antipodal holes. These holes accept a short length of wire deformed on the end like a rivet so that the end is bound inside the ball. The wire is then connected to another ball using the same method. Many of the balls and wires are joined together to form a chain.

The ball python (Python regius), also known as the royal python, is a python species found in sub-Saharan Africa. Like all other pythons, it is a non-venomous constrictor. This is the smallest of the African pythons and is popular in the pet trade, largely due to its small size and typically docile temperament. No subspecies are currently recognized. Life expectancy in captivity is as much as 47 years, though such outcomes require regular care and a clean, well-maintained living environment. The name "ball python" refers to the animal's tendency to curl into a ball when stressed or frightened. The name "royal python"(from the Latin regius) comes from the fact that rulers in Africa would wear the python as jewelry.

A ball hog is a derisive term for a player who handles the ball exclusively to the point of impairing the team. Despite not a violation of the rules of basketball, "ball-hogging" is generally considered unacceptable playing behavior at all levels of basketball competition. The term is highly subjective, and any individual player might be considered a ball hog by some observers but not by others.Ball-hogging usually involves excessive shooting of difficult shots, especially when other players are in advantageous positions. Ball hogs attempt to monopolize their play of the ball, frequently dribbling excessively and infrequently passing the ball to a teammate. Ball-hogging tends to manifest itself statistically as an abnormally high percentage of team shot attempts by the ball hog and often low percentages of shot accuracy and assists. They also tend to have a very poor assist-to-turnover ratio, used as the main statistical indicator of how well a player "shares" the ball.Ball-hogging can be detrimental to a team both immediately and in the long term. For instance, a player with ball-hogging tendencies may overlook or neglect a teammate who is open for a relatively easy shot, choosing instead to take a more difficult shot himself, often at the team's expense. Additionally, repeated ball-hogging by a player can damage a team's cohesiveness and alienate the player from his teammates, coaches, and fans. Another example of a ball hog is a player whose aim is to boost his statistics. This could be done even through assists. A player who tries to do the most of everything - holding the ball and executing all the plays, from scoring to assisting, when it is detrimental to the outcome of the game - can also be known as a ball hog.In professional leagues, when an exceptionally competent player takes control of the ball a large amount of the time, but it is in the team's best interest due to the player's very high shot percentage and low turnover rate, and low availability of similarly skilled players on the team, he is not usually considered a ball hog. The expectation of a professional team is to play in the manner which will produce the most team wins, which will naturally lead to an imbalance among teammates of differing skill levels. However, in amateur and children's basketball, monopolizing the ball is often considered unsportsmanlike regardless of the effect it has on the team's wins.

A ball detent is a simple mechanical arrangement used to hold a moving part in a temporarily fixed position relative to another part. Usually the moving parts slide with respect to each other, or one part rotates within the other.The ball is a single, usually metal sphere, sliding within a bored cylinder, against the pressure of a spring, which pushes the ball against the other part of the mechanism, which carries the detent - which can be as simple as a hole of smaller diameter than the ball. When the hole is in line with the cylinder, the ball falls partially into the hole under spring pressure, holding the parts at that position. Additional force applied to the moving parts will push the ball back into its cylinder, compressing the spring, and allowing the parts to move to another position.Ball detents are commonly found in the selector mechanism of a gearbox, holding the selector rods in the correct position to engage the desired gear. Other applications include clutches that slip at a preset torque, and calibrated ball detent mechanisms are typically found in a torque wrench.Ball detents are one of the mechanisms often used in folding knives to prevent unwanted opening of the blade when carrying it.

Ball back is a piece of terminology in both codes of rugby football.In both codes of rugby, if the ball enters touch, then play is restarted (either by a line-out in rugby union or a scrum in rugby league) level with the point where the ball left the field of play. The exception to this is if the ball is kicked into touch without first bouncing inside the field of play (on the full). In this case, the scrum or line-out is taken from level with the place from where the ball was kicked from, and not from where it entered touch.Ball back is waived in certain circumstances:If a side elects to kick a penalty into touchIf the kicking player is inside his own 22m line when he kicks the ball, and (under the ELVs) the ball has not been immediately passed or run back into the 22 (rugby union only)

A ball gauge is an instrument used by the umpires in cricket to check whether the size of a cricket ball meets the standard measurements mandated by the Laws of Cricket. It is usually in a form somewhat like a pair of handcuffs with two connected rings: one ring has the minimum acceptable diameter, through which the ball should not pass; the other ring has the maximum acceptable diameter, through which the ball should pass.If the ball cannot pass through the maximum diameter, or passes through the minimum diameter, or becomes mis-shapen, the umpires should replace the ball. The replacement ball is ideally an old ball that was used in a previous match for a comparable number of overs as the ball being replaced, so that it has had approximately the same amount of use and wear as the old ball.

Ball lightning is an unexplained atmospheric electrical phenomenon. The term refers to reports of luminous, spherical objects that vary from pea-sized to several meters in diameter. Though usually associated with thunderstorms, the phenomenon lasts considerably longer than the split-second flash of a lightning bolt. Many early reports claim that the ball eventually explodes, sometimes with fatal consequences, leaving behind the odor of sulfur.Until the 1960s, most scientists treated reports of ball lightning skeptically, despite numerous accounts from around the world. Laboratory experiments can produce effects that are visually similar to reports of ball lightning, but how these relate to the natural phenomenon remains unclear.Scientists have proposed many hypotheses about ball lightning over the centuries. Scientific data on natural ball lightning are scarce, owing to its infrequency and unpredictability. The presumption of its existence depends on reported public sightings, and has therefore produced somewhat inconsistent findings. Owing to inconsistencies and to the lack of reliable data, the true nature of ball lightning remains unknown. The first ever optical spectrum of what appears to have been a ball-lightning event was published in January 2014 and included a video at high frame-rate.

Ball washers are typically found on golf courses; on some courses, there is one at every hole. To maintain these aerodynamic properties balls are usually inspected for dirt before play, and washed if required.Ball washers can be operated either manually or electronically. Ball washers for cleaning individual balls consist of a cylindrical housing, in which the ball to be cleaned is inserted. The cleaning of the ball takes place via circulating brushes. For cleaning a larger number of golf balls, machines are used which suck up the balls like a vacuum cleaner, wash them, and put them in a separate net afterward.

A ball bearing motor is an unusual electric motor that consists of two ball-bearing-type bearings, with the inner races mounted on a common conductive shaft, and the outer races connected to a high current, low voltage power supply. An alternative construction fits the outer races inside a metal tube, while the inner races are mounted on a shaft with a non-conductive section (e.g. two sleeves on an insulating rod). This method has the advantage that the tube will act as a flywheel. The direction of rotation is determined by the initial spin which is usually required to get it going.S. Marinov suggests that the device produces motion from electricity without magnetism being involved, operating purely by thermal means. The same explanation is given by Watson, Patel and Sedcole for rotating cylinders (instead of balls). However, H. Gruenberg has given a thorough theoretical explanation based on pure electromagnetism (and neglecting the thermal effects completely). Also, P. Hatzikonstantinou and P. G. Moyssides claim to have found an excellent agreement between the results from the electromagnetic theory and the experiments measuring the total power and efficiency of the motor.

Ball badminton is a sport native to India. It is a racket game, played with a yellow ball made of wool, on a court of fixed dimensions (12 by 24 metres) divided by a net. The game was played as early as 1856 by the royal family in Tanjore, the capital of Thanjavur district in Tamil Nadu, India. It enjoys the greatest popularity in India. Ball badminton is a fast-paced game; it demands skill, quick reflexes, good judgment, agility, and the ability to control the ball with one's wrist.Games are usually played outdoors during the day. As a result, weather conditions wield a considerable influence, and ball badminton's rules allow the effects of weather conditions to be distributed more-or-less evenly between both teams. More recently, indoor versions of the game have been played under artificial lighting. All-India tournaments are conducted regularly using floodlights in Tamil Nadu, Puducherry, Andhra Pradesh, Telangana and Karnataka. Ball Badminton sport is managed by " Ball Badminton Federation of India" Now Ball badminton game is officially recognised game in India. Total 34 units are affiliated to "Ball badminton federation of india " in which 26 are States units, 5 Public sector units and 3 provisional affiliated units.

The ball and beam system consists of a long beam which can be tilted by a servo or electric motor together with a ball rolling back and forth on top of the beam. It is a popular textbook example in control theory.The significance of the ball and beam system is that it is a simple system which is open-loop unstable. Even if the beam is restricted to be very nearly horizontal, without active feedback, it will swing to one side or the other, and the ball will roll off the end of the beam.

Ball bearings

Ball pen

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other.Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.

A ball and chain was a physical restraint device historically applied to prisoners, primarily in the British Empire and its former colonies, from the 17th century until as late as the mid-20th century.A ball and chain believed to date to the 17th century was found in the United Kingdom in 2009. It consists of a sphere of high-grade iron approximately 15 centimetres (5.9 in) across and weighing around 8 kilograms (18 lb). The chain is of some 90 centimetres (35 in) in length and terminates in a leg iron or shackle. The weight of the ball makes it difficult for the restrained person to walk.

It is a popular textbook example in control theory.The significance of the ball and beam system is that it is a simple system which is open-loop unstable. Even if the beam is restricted to be very nearly horizontal, without active feedback, it will swing to one side or the other, and the ball will roll off the end of the beam. To stabilize the ball, a control system which measures the position of the ball and adjusts the beam accordingly must be used.In two dimensions, the ball and beam system becomes the ball and plate system, where a ball rolls on top of a plate whose inclination can be adjusted by tilting it frontwards, backwards, leftwards, or rightwards.

A ball turret was a spherical-shaped, altazimuth mount gun turret, fitted to some American-built aircraft during World War II. The name arose from the turret's spherical housing.It was a manned turret, as distinct from remote-controlled turrets also in use. The turret held the gunner, two heavy machine guns, ammunition, and sights. The Sperry Corporation designed ventral versions that became the most common version, thus the term "ball turret" is most specific to these versions.

Ball splines (Ball Spline bearings) are a special type of linear motion bearing that are used to provide nearly frictionless linear motion while allowing the member to transmit torque simultaneously. There are grooves ground along the length of the shaft (thus forming splines) for the recirculating ground balls to run inside. The outer shell that houses the balls is called a nut rather than a bushing, but is not a nut in the traditional sense—it is not free to rotate about the shaft, but is free to travel up and down the shaft.By increasing the contact area of the ball bearings on the shaft to approximately 45 degrees, the side load and direct load carrying capabilities are greatly increased. Each nut can be individually preloaded at the factory to decrease the available radial play to ensure rigidity. This process not only increases the contact area, increasing direct loading capabilities, but it also restricts any radial movement, increasing the overhung moment capabilities. This creates a sturdier structure that can handle a very strenuous working environment.

In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles. They are used on virtually every automobile made and work similarly to the ball-and-socket design of the human hip joint.A ball joint consists of a bearing stud and socket enclosed in a casing; all these parts are made of steel. The bearing stud is tapered and threaded, and fits into a tapered hole in the steering knuckle. A protective encasing prevents dirt from getting into the joint assembly. Usually, this is a rubber-like boot that allows movement and expansion of lubricant. Motion-control ball joints tend to be retained with an internal spring, which helps to prevent vibration problems in the linkage.The "offset" ball joint provides means of movement in systems where thermal expansion and contraction, shock, seismic motion, and torsional motions, and forces are present.

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary.

Ball transfer units are omnidirectional load-bearing spherical balls mounted inside a restraining fixture. They are identical in principle to a computer trackball (pointing device). Typically the design involves a single large ball supported by smaller ball bearings.They are commonly used in an inverted ball up position where objects are quickly moved across an array of units, known as a ball transfer table, a type of conveyor system. This permits manual transfer to and from machines and between different sections of another conveyor system. They are used in airports for luggage delivery, or in industry as part of manufacturing systems. Prior to the invention of the ball transfer unit, first patented by Autoset Production Ltd in 1958, these applications were solved by the use of inverted casters. However, casters recognise a trail, meaning that the wheels had to align before directional change could be achieved.Ball transfer units can also be used in a non-inverted ball down position as a type of caster, however this use is restricted by load-bearing limitations and the type of floor. Manufacturers have addressed this problem with ball transfer units incorporating re-circulating ball principles, however the inverted position is still the most common application and the least problematic.

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary. The ball assembly acts as the nut while the threaded shaft is the screw. In contrast to conventional leadscrews, ballscrews tend to be rather bulky, due to the need to have a mechanism to re-circulate the balls.Another form of linear actuator based on a rotating rod is the threadless ballscrew, a.k.a. "rolling ring drive". In this design, three (or more) rolling-ring bearings are arranged symmetrically in a housing surrounding a smooth (thread-less) actuator rod or shaft. The bearings are set at an angle to the rod, and this angle determines the direction and rate of linear motion per revolution of the rod. An advantage of this design over the conventional ballscrew or leadscrew is the practical elimination of backlash and loading caused by preload nuts.

The Ball of the Century, also referred to as the Gatting Ball or simply That Ball, is the name given to a cricket delivery bowled by Australian spin bowler Shane Warne to English batsman Mike Gatting on Day Two during the first Test of the 1993 Ashes series (4 June 1993), which took place at Old Trafford, Manchester. With his first ball against England, in his first Ashes Test, Warne produced a spectacular delivery that bowled Gatting out.

The Ball and Roller Bearing Company, also known as American Family Crafts and the Joseph Nutt House and Machine Shop, is a historic industrial complex at 20-22 Maple Avenue in Danbury, Connecticut. The complex includes three buildings, two of which are wood frame and one which is brick. The two wood frame buildings include the Queen Anne-style former home of Joseph Nutt, who established a machine shop providing services to Danbury's hat making industry in 1886. Nutt's home also served as his company's office, and is attached to a single-story monitor-roofed brick structure. The factory is most notable as the location where Lewis Heim, owner of the Ball and Roller Bearing Company, invented the modern centerless grinding machine in 1917.The complex was listed on the National Register of Historic Places on August 25, 1989.

A ball chain is a type of chain consisting of small sheet metal balls connected via short lengths of wire.The balls are hollow and have two small antipodal holes. These holes accept a short length of wire deformed on the end like a rivet so that the end is bound inside the ball. The wire is then connected to another ball using the same method. Many of the balls and wires are joined together to form a chain. Because of the connection method, the chain can swivel on itself unrestrictedly, which helps prevent kinking. However, the chain has a relatively low strength. Ball chains are also sometimes known as snake link.The most common ball chain accessories are connectors. Each end of a connector is able to surround a ball at the end of a chain and snap over its wire connection, which holds it secure. These can be used to connect two lengths of chain, or to connect the ends of the same chain to form a loop. The connectors require no tools to apply or remove and are reusable.Other common accessories include other terminations similar to the connectors, but with a different connection on one end, such as a screw hole for semi-permanent affixing of a chain.Common uses of ball chain are for pull cords on light fixtures and ceiling fans, keychains, as retaining chains for things such as counter pens, and dogtag chains.A typical width is Size #3, or 2.4mm steel ball chain. In the jewelry industry, pure 925 Sterling Silver may be in 1mm, 1.2mm, 1.5mm, 1.8mm, and 2.2mm ball chain.

The ball tie or balltie is a bondage position in which a person is bound tightly into a ball position. A ball position (also called a fetal position) is one where the legs are bent double so the heels press against the bottom; the legs should also be brought up so that the thighs are pressed against the chest. Pressing the thighs against the abdomen may restrict breathing.The hands may be tied either in front or behind the back, however behind the back is more typical.

A ball and chain was a physical restraint device historically applied to prisoners, primarily in the British Empire and its former colonies, from the 17th century until as late as the mid-20th century.A ball and chain believed to date to the 17th century was found in the United Kingdom in 2009. It consists of a sphere of high-grade iron approximately 15 centimetres (5.9 in) across and weighing around 8 kilograms (18 lb).

Ball bonding is a type of wire bonding, and is the most common way to make the electrical interconnections between a chip and the outside world as part of semiconductor device fabrication.Gold or copper wire can be used, though gold is more common because its oxide is not as problematic in making a weld. If copper wire is used, nitrogen must be used as a cover gas to prevent the copper oxides from forming during the wire bonding process.

Ball clays are kaolinitic sedimentary clays that commonly consist of 20–80% kaolinite, 10–25% mica, 6–65% quartz. Localized seams in the same deposit have variations in composition, including the quantity of the major minerals, accessory minerals and carbonaceous materials such as lignite. They are fine-grained and plastic in nature, and, unlike most earthenware clays, produce a fine quality white-coloured pottery body when fired, which is the key to their popularity with potters.Ball clays are relatively scarce deposits due to the combination of geological factors needed for their formation and preservation. They are mined in parts of the Eastern United States and from three sites in Devon and Dorset in South West England. They are commonly used in the construction of many ceramic articles, where their primary role, apart from their white colour, is to either to impart plasticity or to aid rheological stability during the shaping processes.

Ball de bastons (Catalan pronunciation: [ˈbaʎ də βəsˈtons], stick dance) is the name of a ritual weapon dance spread throughout Europe and the rest of the Iberian area (cossiers in Majorca, Portuguese pauliteiros, Aragonese palotiau, Basque ezpatadantza and Spanish paloteo or troqueado) but mostly in Catalonia. English and Welsh Morris dances are well-known relatives to these traditions.

The ball-flower (also written ballflower) is an architectural ornament in the form of a ball inserted in the cup of a flower, which came into use in the latter part of the 13th, and was in great vogue in the early part of the 14th century. It is generally placed in rows at equal distances in the hollow of a moulding, frequently by the sides of mullions. The earliest known is said to be in the west part of Salisbury Cathedral, where it is mixed with the tooth ornament.

In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles. They are used on virtually every automobile made and work similarly to the ball-and-socket design of the human hip joint.A ball joint consists of a bearing stud and socket enclosed in a casing; all these parts are made of steel. The bearing stud is tapered and threaded, and fits into a tapered hole in the steering knuckle.

Ball propellant is a form of nitrocellulose used in small arms cartridges. It has been trademarked as Ball Powder by Olin Corporation and marketed as spherical powder by Hodgdon Powder Company. Ball propellant can be manufactured more rapidly with greater safety and lesser expense than extruded propellants. Ball propellant was first used to load military small arms cartridges during World War II and has been manufactured for sale to handloading civilians since 1960.

A ball head is a metal or plastic apparatus placed on top of a tripod that increases stability and provides faster, more accurate rotation for the photographer. They are also lighter than traditional three-way pan-tilt tripod heads. With fewer parts and a much simpler mechanism, ball heads are usually preferred by more advanced photographers. However, they are usually quite expensive due to the precision-made pieces inside and the detailed finish outside -- most professional-quality heads are more than $200 USD, although some heads are available for less than $100.

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races.The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft).

Balla (pronounced Bal) (Irish: Balla, meaning "wall"), is a village in County Mayo, Ireland on the N60 National secondary road, the main road between Castlebar and Claremorris. The economy of the village survives mainly on passing trade, from the busy N60 which carries over 7,000 vehicles through the village every day. Balla has only one street. It is notable for its round tower. It used to be a significant shop and market centre. It fell into decline and lost its railway station, but has enjoyed something of a revival as a residential area for people working in Castlebar.In early times the village was known as 'Ros Dairbhreach', meaning 'The Height of the Oak Wood'. The continuing importance of the oak to the local community is reflected in the appropriately named "Dawn Oak 2000" project. At the beginning of the 21st century, 2000 oak trees were planted, creating a new wood in Balla's town park.

Ball of Fire is a 1941 American screwball comedy film directed by Howard Hawks and starring Gary Cooper and Barbara Stanwyck. This Samuel Goldwyn Productions film (originally distributed by RKO) concerns a group of professors laboring to write an encyclopedia and their encounter with a nightclub performer who provides her own unique knowledge.The supporting cast includes Oskar Homolka, S. Z. Sakall, Henry Travers, Richard Haydn, Dana Andrews, and Dan Duryea.

Ball v. United States, 163 U.S. 662 (1896), is one of the earliest United States Supreme Court case interpreting the Double Jeopardy Clause.In 1889, defendants Millard Fillmore Ball, John C. Ball, and Robert E. Boutwell were indicted for the murder of William T. Box. The jury acquitted Millard Fillmore Ball and convicted John C. Ball and Robert E. Boutwell. The convicted defendants appealed to the Supreme Court, which reversed their convictions in 1891, holding that the indictment was insufficient. All three were indicted for the murder a second time. All three plead prior jeopardy. The trial court rejected all three pleas, and all three were convicted the second time.On the second appeal, the Supreme Court reversed Millard Fillmore Ball's conviction. Departing from the common law rule of the England, and from early decisions of the state supreme courts of New York and Massachusetts, the Court held that–under the Double Jeopardy Clause—the insufficiency of the first indictment could not remove the jeopardy bar of acquittal, as long as the first court had jurisdiction.The Court rejected John C. Ball and Robert E. Boutwell's double jeopardy arguments, holding that they could be retried after their prior convictions were reversed on appeal. The court also rejected their remaining arguments.

Ball im Savoy (Ball at the Savoy) is an operetta in three acts and a prelude by Paul Abraham to a libretto by Alfred Grünwald and Fritz Löhner-Beda.It premiered on 23 December 1932 at the Großes Schauspielhaus, Berlin The English language premiere was on 8 September 1933 at the Drury Lane Theatre, London, under the title Ball At The Savoy. This was Abraham's last major success.Although Ball im Savoy is a relatively recent operetta, its characters follow the classic scheme: Aristide (tenor) is a rueful rake, excruciated by the possible betrayal. Madeleine (soprano) is a more modern person, ready to give as good as she gets, albeit plagued by scruples: a feminist before the term existed, who receives approval from the other women. Mustafa represents the stock comic. More interesting is Daisy (soubrette): sly, brave, she knows what she wants and how to get it.

On 20 August 2006, during the fourth day of the fourth Test between England and Pakistan at The Oval, Darrell Hair and fellow umpire Billy Doctrove ruled that the Pakistani team had been involved in ball tampering. They awarded five penalty runs to England and offered them a replacement ball. The Pakistani players refused to take the field after the tea break in protest at the decision. The umpires left the field, directed the Pakistani players to resume play and returned once more 15 minutes later. After waiting two more minutes the umpires removed the bails and declared England winners by forfeiture. This was the first such end to a Test match in over 1000 tests. The Pakistani team did take to the field 25 minutes later, 55 minutes after the umpires first took to the field for a resumption of play, but by then it was Hair and Doctrove themselves who pointed out that the game had already ended with a Pakistani forfeiture the moment the bails were removed, even though both teams were willing to continue the match. The Test was abandoned, with the match awarded to England.

Ball back is a piece of terminology in both codes of rugby football.In both codes of rugby, if the ball enters touch, then play is restarted (either by a line-out in rugby union or a scrum in rugby league) level with the point where the ball left the field of play. The exception to this is if the ball is kicked into touch without first bouncing inside the field of play (on the full).

Ball games (or ballgames), also ball sports, are any form of game or sport which feature a ball as part of play. These include games such as association football (soccer), baseball, basketball, and American football. Such games have diverse rules and histories and are of mostly unrelated origins. Ball games can be defined in several broad types:Bat-and-ball games, such as baseball and cricket.Racquet and ball games, such as tennis, squash and badminton.Hand and ball-striking games, such as various handball codes, rebound handball and four square.Goal sports, usually team sports such as basketball and all forms of football, lacrosse, and hockey (the derived sport of ice hockey, which uses a puck rather than a ball, is classified with the goal, team ball sports for some purposes).Non-racquet net sports, such as volleyball and sepak takraw.Target sports or precision sports, such as bowling, lawn bowls, croquet, and golf, as well as cue sports, including snooker, pool, and other forms of billiards (the sport of curling, which uses a stone rather than a ball, is classified with target or precision sports for some purposes).

For the type of end mill, see Ball nose cutter.A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls. The grinding media is the balls, which may be made of steel (chrome steel), stainless steel, ceramic, or rubber. The inner surface of the cylindrical shell is usually lined with an abrasion-resistant material such as manganese steel or rubber. Less wear takes place in rubber lined mills. The length of the mill is approximately equal to its diameter.The general idea behind the ball mill is an ancient one, but it was not until the industrial revolution and the invention of steam power that an effective ball milling machine could be built. It is reported to have been used for grinding flint for pottery in 1870.

A ball detent is a simple mechanical arrangement used to hold a moving part in a temporarily fixed position relative to another part. Usually the moving parts slide with respect to each other, or one part rotates within the other.The ball is a single, usually metal sphere, sliding within a bored cylinder, against the pressure of a spring, which pushes the ball against the other part of the mechanism, which carries the detent - which can be as simple as a hole of smaller diameter than the ball.

The ball tie or balltie is a bondage position in which a person is bound tightly into a ball position. A ball position (also called a fetal position) is one where the legs are bent double so the heels press against the bottom; the legs should also be brought up so that the thighs are pressed against the chest. Pressing the thighs against the abdomen may restrict breathing.The hands may be tied either in front or behind the back, however behind the back is more typical. If behind, there may also be elbow bondage, or the arms may be in a reverse prayer position, with ropes round the arms and torso (or arms and legs) to hold the arms firmly against the back. If in front, the arms may be tied hugging the legs, or possibly with each wrist bound to the opposite elbow. The ankles may also be tied together, as well as the knees. Typically the ankles are tied to the thighs in a Frogtie, unlike the image at right.Sometimes the bound person wears high-heeled shoes and has ropes wrapped round the heels and fixed to the wrists. This adds to the visual impact, but should only be used as a supplement to other secure bondage; if it takes the main strain, the shoes may come off or the heels may break off. When tied this way the shoes usually cannot be removed.The head may be pulled back in some way, such as in head bondage. However, some purists argue that this goes against the idea of binding into a ball. Alternatively, the head can be pulled forward to force the chin to press against the chest.The position is both very stringent and (some would argue) stimulating. At the same time it is a comfortable position so that the subject may remain in it for quite some time.The ball tie is one of the positions possible in self-bondage, but mobility is so limited that several independent escape mechanisms should be used, in addition to the usual bondage safety advice.
