A pulley is a simple contraption which is used as a base for many complicated machines. It is one of the six simple machines. It consists of a wheel which has a furrow along its rim, also referred to as a sheave, that is created to hold a rope or a cable. Pulleys are generally used in groups devised to decrease the quantity of force necessary to lift a load. Nonetheless, the same quantity of work is required for the load to attain the same height as it would with no use of the pulleys. The magnitude of the force is decreased, but it must perform through more distance. The attempt required to pull a load upwards is approximately the weight of the load divided by the amount of wheels present.

Basically, a
pulley changes the direction of an applied force. Thus, for instance,
you can pull on the cable of the pulley, and it will pull a weight.
