A pulley is a wheel on an axle or shaft that is designed to support motion and change of path of a taut cable connection or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley backed by a body or shell that will not transfer power to a shaft, but can be used to guide the wire or exert a induce, the supporting shell is called a prevent, 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 travel factor of a pulley system could be a rope, wire, belt , or chain .
The earliest evidence of pulleys date back 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 devices used to lift weights.[3] Pulleys are assembled to create a block and tackle in order to provide mechanical advantage to use significant forces. Pulleys are likewise assembled within belt and chain drives in order to transmit power in one rotating shaft to another.
The pulley, a straightforward machine, helps to perform work by changing the direction 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 rise off the ground. There are also movable pulleys and pulley systems.
