Detailed explanation-1: -The movable pulley allows the effort to be less than the weight of the load. The movable pulley also acts as a second class lever. The load is between the fulcrum and the effort. The main advantage of a movable pulley is that you use less effort to pull the load.
Detailed explanation-2: -There are three main types of pulleys: fixed, movable, and compound.
Detailed explanation-3: -A movable pulley is a type of pulley which is free to move up and down, and its one end is attached to a ceiling or other object by two lengths of the same rope. Movable pulleys are used in construction cranes, modern elevators, and some types of weight lifting machines at the gym.
Detailed explanation-4: -A single fixed pulley is defined as a pulley with its axis of rotation fixed in place. It’s used to shift the effort’s direction. Whereas, a movable pulley is one that can move up and down and is connected to a ceiling or another object by two lengths of the same rope.
