A movable pulley is a pulley exactly where when you go a hefty item, the drum moves with it. There is no change in the direction of the force you need to have to apply, but the load will “truly feel” lighter than it truly is. For case in point, if you happen to be 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 are pulling in the exact same direction.
