A pulley is a wheel on an axle or shaft that is designed to support movement and change of way of a taut wire or belt, or transfer of vitality between your shaft and wire or belt. Regarding a pulley reinforced by a frame or shell that will not transfer capacity to a shaft, but is employed to guide the cable or exert a force, the assisting 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 locate the wire or belt. The drive component of a pulley system can 
be a rope, wire, 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) identified the pulley as one of six simple devices used to strength train.[3] Pulleys will be assembled to form a block and tackle in order to provide mechanical advantage to apply significant forces. Pulleys are as well assembled as part of belt and chain drives as a way to transmit power in one rotating shaft to some other.
The pulley, a simple machine, helps to perform work by changing the path of forces and making easier the moving of huge objects. … With this sort of pulley – named a fixed pulley – pulling down on a rope makes an object rise off the ground. There are also movable pulleys and pulley devices.
