A pulley is a wheel on an axle or shaft that’s designed to support activity and change of route of a taut cable or belt, or transfer of vitality between the shaft and cable or belt. In the case of a pulley reinforced by a frame or shell that does not transfer capacity to a shaft, but is used to guide the cable or exert a force, the supporting shell is named a prevent, and the pulley may be called a sheave.

Pulleys are likewise assembled within belt and chain drives in order to transmit power in one rotating shaft to another.
The pulley, a straightforward machine, helps to perform work by changing the way of forces and producing easier the moving of significant objects. … With this sort of pulley – known as a fixed pulley – pulling down on a rope makes an object surge off the ground. There are also movable pulleys and pulley systems.
