Using the example above. If the load is lifted 2 metres, above the pulley wheel-the rope on the right hand side must be shortened by one metre and this also applies to the left hand side. Therefore, the effort can be seen to move twice as far as the load. A pulley system with the effort applied from above is very difficult to use. The most comfortable way to use a single moving pulley is combine it with a fixed pulley, seen below.
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell which does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain. Hero of Alexandria identified the pulley as one of six simple machines used to lift weights.
