A pulley is a wheel on an axle or shaft that is designed to support movements and change of route of a taut wire or belt, or transfer of electric power between the shaft and wire or belt. Regarding a pulley 
reinforced by a frame or shell that does not transfer power to a shaft, but is utilized to guide the cable or exert a pressure, the helping shell is named a block, and the pulley may be called a sheave.
A pulley might have a grooveor grooves between flanges around its circumference to find the cable or belt. The drive factor of a pulley system can 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 one of six simple devices used to lift weights.[3] Pulleys happen to be assembled to form a prevent and tackle to be able to offer mechanical advantage to apply significant forces. Pulleys are likewise assembled within belt and chain drives as a way to transmit power in one rotating shaft to some other.
The pulley, a straightforward machine, helps to perform work by changing the way of forces and making easier the moving of huge objects. … With this kind of pulley – referred to as a set pulley – pulling down on a rope makes an object go up off the ground. Additionally, there are movable pulleys and pulley systems.
