What Is a Movable Pulley?

Answer

A movable pulley is an object that moves with the load allowing for the handler to use less effort. It acts as a second class lever but does not change direction of the effort force. However, its main disadvantage is that it has to be pulled or pushed up or down since the load is between the fulcrum and the effort.
