What Does Movable Pulley Mean?
A movable pulley is a kind of pulley which moves with the load. A pulley can be defined as a simple device that involves a chain, rope or belt running around a wheel. The main function that pulleys are involved in is lifting heavy loads. The most important advantage of a movable pulley is that the effort involved is much less than compared to the load’s weight. The movable pulley performs the function of acting as a sort of second class lever. The load is contained between the effort and the fulcrum. The addition of a second pulley can help reduce the effort involved even further. In a movable pulley one end of the rope or chord is attached to a fixed place, it then runs around the pulley and the other end is free to apply effort. The movable pulley directly attaches to the load.
