Movable Pulley: A pulley that rotates and translates according to the motion of the pulley or belt. This is normally employed in blocking and deal with systems, which I will make clear later.
In a compound pulley method, there is both a movable pulley and a fastened pulley. This implies that not only does the load “truly feel” lighter, but you can also modify the path of the drive. Even though this type of configuration can shift large hundreds extremely very easily, it comes at the value of necessitating fairly a bit of motion to do the work.
