A movable pulley is a pulley where when you go a weighty object, the drum moves with it. There is no modify in the path of the drive you need to have to utilize, but the load will “come to feel” lighter than it truly is. For example, if you might be hauling a weighty hay bale up the barn’s attic, a moveable pulley will make the load come to feel a whole lot lighter, even though you are pulling in the identical course.
