A pulley is a wheel on an axle or shaft that’s designed to support motion and change of course of a taut cable or belt, or transfer of ability between your shaft and wire or belt. In the case of a pulley reinforced by a frame or shell that will not transfer power to a shaft, but is utilized to guide the cable or 
exert a push, the helping shell is called a block, and the pulley may be called a sheave.
A pulley may have a grooveor grooves between flanges around its circumference to find the wire or belt. The drive component of a pulley program can be a rope, cable, belt , or chain .
The earliest proof pulleys date back to Mesopotamia in the early 2nd millennium BCE,[1] and Ancient Egypt in the Twelfth Dynasty (1991-1802 BCE).[2] In Roman Egypt ,Hero of Alexandria (c. 10-70 CE) discovered the pulley as you of six simple equipment used to lift weights.[3] Pulleys happen to be assembled to create a prevent and tackle in order to present mechanical advantage to use large forces. Pulleys are as well assembled within belt and chain drives so that you can transmit power from one rotating shaft to some other.
The pulley, a simple machine, helps to perform work by changing the direction of forces and producing easier the moving of large objects. … With this type of pulley – named a fixed pulley – pulling down on a rope makes an object surge off the ground. There are also movable pulleys and pulley systems.
