A movable pulley is a pulley the place when you move a weighty object, the drum moves with it. There is no adjust in the path of the power you need to have to implement, but the load will “really feel” lighter than it actually is. For example, if you’re hauling a weighty hay bale up the barn’s attic, a moveable pulley will make the load really feel a lot lighter, even though you might be pulling in the identical direction.
