A pulley is a wheel on an axle or shaft that is designed to support movement and change of course of a taut cable connection or belt, or transfer of electric power between the shaft and wire or belt. In the case of 
a pulley backed by a body or shell that does not transfer capacity to a shaft, but is utilized to guide the wire or exert a pressure, the helping shell is named a prevent, and the pulley may be called a sheave.
A pulley might have a grooveor grooves between flanges around its circumference to locate the wire or belt. The drive component of a pulley system can be a rope, wire, belt , or chain .
The earliest evidence of 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) recognized the pulley as you of six simple equipment used to lift weights.[3] Pulleys will be assembled to create a block and tackle in order to give mechanical advantage to apply 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 straightforward machine, helps to perform work by changing the path of forces and producing easier the moving of significant objects. … With this type of pulley – named a set pulley – pulling down on a rope makes an object grow off the ground. There are also movable pulleys and pulley devices.
