Wheel
A wheel is a circular component that is intended to rotate on an axial bearing. The wheel is one of the main 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.

Famous quotes containing the word wheel:
“A wheel that can be turned though nothing else moves with it, is not a part of the mechanism.”
—Ludwig Wittgenstein (1889–1951)
“Helpless, unknown, and unremembered, most human beings, however sensitive, idealistic, intelligent, go through life as passengers rather than chauffeurs. Although we may pretend that it is the chauffeur who is the social inferior ... most of us, like Toad of Toad Hall, would not mind a turn at the wheel ourselves.”
—Ralph Harper (b. 1915)
“It might become a wheel spoked red and white
In alternate stripes converging at a point
Of flame on the line, with a second wheel below,
Just rising, accompanying, arranged to cross,
Through weltering illuminations, humps
Of billows, downward, toward the drift-fire shore.”
—Wallace Stevens (1879–1955)
