A movable pulley is a pulley the place when you move a weighty item, the drum moves with it. There is no alter in the course of the power you need to have to use, but the load will “truly feel” lighter than it really is. For illustration, if you are hauling a heavy hay bale up the barn’s attic, a moveable pulley will make the load truly feel a lot lighter, even although you might be pulling in the same direction.
