A device that makes work easier

Simple machine consisting of a large wheel rigidly secured to a smaller wheel or shaft.

This pulley does not rise or fall with the load being moved.

This pulley rises and falls with the load being moved.

Can be composed of one or two inclined planes, and used for separating devices.

The force you apply:

The force which is applied to the task:

The ratio of a force produced by a machine, to the force applied to it:
