A pulley is a wheel on an axle or shaft that is designed to support motion and change of route of a taut cable or belt, or transfer of vitality between the shaft and wire or belt. In the case of a pulley reinforced by a body or shell that 
will not transfer power to a shaft, but is employed to guide the cable or exert a induce, the supporting shell is called a block, and the pulley may be called a sheave.
A pulley might have a grooveor grooves between flanges around its circumference to locate the cable or belt. The drive component of a pulley program could be a rope, cable, 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) determined the pulley as you of six simple devices 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 likewise assembled within belt and chain drives so that you can transmit power from one rotating shaft to some other.
The pulley, a simple machine, really helps to perform work by changing the path of forces and producing easier the moving of huge objects. … With this kind of pulley – called a set pulley – pulling down on a rope makes an object surge off the ground. There are also movable pulleys and pulley devices.
