A pulley is a wheel on an axle or shaft that's designed to support motion and change of route of a taut cable or belt, or transfer of electricity between the shaft and cable or belt. In the case of a pulley supported by a body or shell that will not transfer capacity to a shaft, but is employed to guide the wire or exert a push, the assisting shell is named 
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 travel factor of a pulley system could be a rope, cable, belt , or chain .
The earliest evidence of pulleys date back again to Mesopotamia in the first 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) identified the pulley as you of six simple equipment used to lift weights.[3] Pulleys are assembled to create a prevent and tackle in order to offer mechanical advantage to use large forces. Pulleys are likewise assembled within belt and chain drives to be able to transmit power in one rotating shaft to another.
The pulley, a straightforward machine, helps to perform work by changing the course of forces and producing easier the moving of significant objects. ... With this type of pulley - named a fixed pulley - pulling down on a rope makes an object grow off the ground. There are also movable pulleys and pulley systems.
