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:

    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 word “revolution” itself has become not only a dead relic of Leftism, but a key to the deadendedness of male politics: the “revolution” of a wheel which returns in the end to the same place; the “revolving door” of a politics which has “liberated” women only to use them, and only within the limits of male tolerance.
    Adrienne Rich (b. 1929)

    The wheel of fortune guide you,
    The boy with the bow beside you
    Run aye in the way
    Till the bird of day
    And the luckier lot betide you.
    Ben Jonson (1572–1637)
