The wheel and axle is a simple machine consisting of a wheel attached to the smaller axle so that these two parts rotate with each other in which a force is transferred from one to the other. The wheel and axle can be viewed as a version of the Lever, with a drive force applied tangentially to the perimeter of the wheel, and a load force applied to the axle supported in a bearing, which serves as a fulcrum.
