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.

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:

    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)

    To sum up:
    1. The cosmos is a gigantic fly-wheel making 10,000 revolutions a minute.
    2. Man is a sick fly taking a dizzy ride on it.
    3. Religion is the theory that the wheel was designed and set spinning to give him the ride.
    —H.L. (Henry Lewis)

    The wheel is come full circle.
    William Shakespeare (1564–1616)
