A movable pulley is a pulley the place when you move a weighty item, the drum moves with it. There is no adjust in the course of the power you want to apply, but the load will “really feel” lighter than it actually is. For illustration, if you’re hauling a large hay bale up the barn’s attic, a moveable pulley will make the load really feel a great deal lighter, even even though you might be pulling in the very same route.
