Rotation Rack
Rotation or rotational/rotary motion is the circular movement of an object around a central line, known as an ''axis of rotation''. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a ''center of rotation''. A solid figure has an infinite number of possible axes and angles of rotation, including chaotic rotation (between arbitrary orientations), in contrast to rotation around a axis. The special case of a rotation with an internal axis passing through the body's own center of mass is known as a spin (or ''autorotation''). In that case, the surface intersection of the internal ''spin axis'' can be called a ''pole''; for example, Earth's rotation defines the geographical poles. A rotation around an axis completely external to the moving body is called a revolution (or ''orbit''), e.g. Earth's orbit around the Sun. The ends of the external ''axis of revolution'' can be ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Billiards Table
A billiard table or billiards table is a bounded table on which cue sports are played. In the modern era, all billiards tables (whether for carom billiards, Pool (cue sports), pool, Russian pyramid, pyramid or snooker) provide a flat surface usually made of quarried slate, that is covered with cloth (usually of a tightly woven worsted wool called baize), and surrounded by vulcanized rubber cushions, with the whole thing elevated above the floor. More specific terms are used for specific sports, such as snooker table and pool table, and different-sized billiard balls are used on these table types. An obsolete term is billiard board, used in the 16th and 17th centuries. Parts and equipment Cushions Cushions (also sometimes called "rail cushions", "cushion rubber", or rarely "bumpers") are located on the inner sides of a table's wooden . There are several different materials and design philosophies associated with cushion rubber. These cushions are made from an elastic material suc ...

Rack (billiards)
A rack (sometimes called a triangle) is a piece of equipment that is used to place billiard balls in their starting positions at the beginning of a pocket billiards game. ''Rack'' may also be used as a verb to describe the act of setting billiard balls in their starting positions (e.g. "to rack the balls"), or as a noun to describe a set of balls that are in their starting positions (e.g. "a rack of balls", more often called a ''pack'' or a ''pyramid'' in British English). Traditional racks are in the form of triangular frames, usually made from wood, plastic or metal. A modern variation, called a ''template rack'', is made from a thin material (usually 0.14 mm or less) that contains precision cut-outs to hold the balls in place. Purported benefits of template racks include a more consistent racking, and their popularity has warranted specific inclusion in profession rules. Unlike traditional racks, template racks are left on the table during the break shot and removed at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Billiard Balls
A billiard ball is a small, hard ball used in cue sports, such as carom billiards, pool, and snooker. The number, type, diameter, color, and pattern of the balls differ depending upon the specific game being played. Various particular ball properties such as hardness, friction coefficient, and resilience are important to accuracy. History Early balls were made of various materials, including wood and clay (the latter remaining in use well into the 20th century). Although affordable ox-bone balls were in common use in Europe, elephant ivory was favored since at least 1627 until the early 20th century; the earliest known written reference to ivory billiard balls is in the 1588 inventory of Thomas Howard, 4th Duke of Norfolk. This is a revised version of ''The Story of Billiards and Snooker'', 1979. Dyed and numbered balls appeared around the early 1770s. By the mid-19th century, elephants were being slaughtered for their ivory at an alarming rate, just to keep up with the de ...

Kelly Pool
Kelly pool (also known as pea pool, pill pool, keeley, the keilley game, and killy) is a pool game played on a standard pool table using a standard set of 16 pool balls.

Pyramid Pool
Pyramid pool, or simply pyramids, is a form of Pool (cue sports), pool that was played mainly in the 19th century. It was one of several pool games that were popular at this time, and was forerunner to modern games such as eight-ball, Blackball (pool), blackball, straight pool, and Russian pyramid. Along with black pool, it was one of the progenitor cue sports of snooker. Rules were racked in a triangle with any remaining balls placed at the back of the triangle. It could be played by several players, with an agreed stake per ball pocketed, or with just two players in which case the winner is the one to first sink over half the balls. Teams were also allowed if there were an even number of players. In early versions of the game, when one object ball remained, the game shifted so one player took possession of the original cue ball, while the other used the object ball, as they attempted to sink the other player's designated ball. This rule was dropped in the United States during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
