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.
Common examples are found in transport applications. A wheel greatly reduces friction by facilitating motion by rolling together with the use of axles. In order for wheels to rotate, a moment needs to be applied to the wheel about its axis, either by way of gravity, or by the application of another external force or torque.

Famous quotes containing the word wheel:
“So I was glad of the fogs
Taking me to you
Undetermined summer thing eaten
Of grief and passage where you stay.
The wheel is ready to turn again.”

“Helpless, unknown, and unremembered, most human beings, however sensitive, idealistic, intelligent, go through life as passengers rather than chauffeurs.

—Ralph Harper (b. 1915)
“The wheel and the brake have different duties, but also one in common: to hurt one another.”
