Windlass

Description

A Windlass or Wheel and Axle is seen wherever there is a winding handle type arrangement (e.g. on a Winch). They can be regarded as two different diameter pulleys locked together: the large one, described by the sweep of the handle, being used to apply the effort and the smaller one, being the diameter of the axle, used to lift the load.

Features and Applications

The Mechanical Advantage of the Wheel and Axle therefore can be calculated as the diameter swept by the handle divided by the diameter of the axle
