A movable pulley is a pulley the place when you move a heavy item, the drum moves with it. There is no alter in the route of the force you require to apply, but the load will “feel” lighter than it actually is. For instance, if you might be hauling a large hay bale up the barn’s attic, a moveable pulley will make the load feel a good deal lighter, even however you’re pulling in the exact same direction.
