Wheel and Axel
The wheel and axle is one of six simple machines identified by Renaissance scientists drawing from Greek texts on technology. The wheel and axle is generally considered to be a wheel attached to an axle so that these two parts rotate together in which a force is transferred from one to the other. In this configuration a hinge, or bearing, supports the rotation of the axle.
Hero of Alexandria identified the wheel and axle as one of five simple machines used to lift weights. This is thought to have been in the form of the windlass which consists of crank or pulley connected to a cylindrical barrel that provides mechanical advantage to wind up a rope and lift a load such as a bucket from a well.
This system is a version of the lever with loads applied tangentially to the perimeters of the wheel and axle, respectively, that are balanced around the hinge, which is the fulcrum. The mechanical advantage of the wheel and axle is the ratio of the distances from the fulcrum to the applied loads, or what is the same thing the ratio of the radial dimensions of the wheel and axle.
