A wheel is a circular component that is intended to rotate on an axle bearing. The wheel is one of the key components of the wheel and axle which is one of the six simple machines. Wheels, in conjunction with axles, allow heavy objects to be moved easily facilitating movement or transportation while supporting a load, or performing labor in machines. Wheels are also used for other purposes, such as a ship's wheel, steering wheel, potter's wheel, and flywheel.
A water wheel is a machine for converting the energy of flowing or falling water into useful forms of power, often in a watermill. A water wheel consists of a wheel, with a number of blades or buckets arranged on the outside rim forming the driving car. Water wheels were still in commercial use well into the 20th century but they are no longer in common use. Uses included milling flour in gristmills, grinding wood into pulp for papermaking, hammering wrought iron, machining, ore crushing and pounding fibre for use in the manufacture of cloth.
John Archibald Wheeler was an American theoretical physicist. He was largely responsible for reviving interest in general relativity in the United States after World War II. Wheeler also worked with Niels Bohr to explain the basic principles of nuclear fission. Together with Gregory Breit, Wheeler developed the concept of the Breit–Wheeler process. He is best known for popularizing the term "black hole" for objects with gravitational collapse already predicted during the early 20th century, for inventing the terms "quantum foam", "neutron moderator", "wormhole" and "it from bit", and for hypothesizing the "one-electron universe". Stephen Hawking called Wheeler the "hero of the black hole story".
William Morton Wheeler was an American entomologist, myrmecologist and professor at Harvard University.
Four-wheel drive, also called 4×4 or 4WD, refers to a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges.

The Wheeler–Feynman absorber theory, named after its originators, the physicists, Richard Feynman, and John Archibald Wheeler, is a theory of electrodynamics based on a relativistic correct extension of action at a distance electron particles. The theory postulates no independent field.
Wire wheels, wire-spoked wheels, tension-spoked wheels, or "suspension" wheels are wheels whose rims connect to their hubs by wire spokes. Although these wires are considerably stiffer than a similar diameter wire rope, they function mechanically the same as tensioned flexible wires, keeping the rim true while supporting applied loads. The term suspension wheel should not be confused with vehicle suspension.
A kugelblitz is a theoretical astrophysical object predicted by general relativity. It is a concentration of heat, light or radiation so intense that its energy forms an event horizon and becomes self-trapped. In other words, if enough radiation is aimed into a region of space, the concentration of energy can warp spacetime so much that it creates a black hole. This would be a black hole whose original mass–energy was in the form of radiant energy rather than matter, however as soon as it forms, it is indistinguishable from an ordinary black hole.
Two-Fisted Law is a 1932 American pre-Code Western film directed by D. Ross Lederman for Columbia Pictures, starring Tim McCoy and featuring John Wayne playing a character named "Duke". The picture also features Alice Day, Wheeler Oakman, Tully Marshall, Wallace MacDonald, and Walter Brennan.
In automobiles, the axle track is the distance between the hub flanges on an axle. Wheel track, track width or simply track refers to the distance between the centerline of two wheels on the same axle. In the case of an axle with dual wheels, the centerline of the dual wheel assembly is used for the wheel track specification. Axle and wheel track are commonly measured in millimetres or inches.
Clarence is a 1922 American silent comedy drama, based on the 1919 play by Booth Tarkington, produced by Famous Players–Lasky and distributed through Paramount Pictures. It was directed by William C. deMille and starred Wallace Reid in his penultimate screen appearance.
The Imperial Austrian Exhibition world's fair was held at Earl's Court in London in 1906. It opened on 20 June and closed on 6 October.
The Wheel of Life is a 1929 American pre-Code romantic drama sound film directed by Victor Schertzinger and starring Richard Dix and Esther Ralston. It was produced and distributed by Paramount Pictures.
The Wyoming United States House election for 1896 was held on November 3, 1896. Democratic John Eugene Osborne defeated Republican incumbent Frank Wheeler Mondell with 49.14% of the vote making Mondell the third incumbent Representative from Wyoming to lose reelection and was the third time in a row that the incumbent had lost. It was the first time that the House election was won with only a plurality of the votes.
The family firm John Pilling and Sons Ltd, made hand, dandy and power looms from 1819. It started in Trawden making hand, dandy and then wooden framed wiper power looms and moved to Colne to make cast iron Lancashire Looms in 1849/50. They continued manufacturing until 1980. The firm also owned several weaving mills and remained in business until 2005 as a mill premises management company. During the wars it made huge quantities of shells, grenades, tank and aircraft parts.
The 1876 United States presidential election in Oregon took place on November 7, 1876, as part of the 1876 United States presidential election. Voters chose three representatives, or electors to the Electoral College, who voted for president and vice president.
