Detailed explanation-1: -A fixed pulley is a pulley that is attached to a structure, it can not move relative to the structure. A moveable pulley is a pulley that can change position relative to the structure. Pulleys can also be combined into what is known as a pulley system. A pulley system is when you combine two or more pulleys.
Detailed explanation-2: -A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag. A movable pulley is a pulley that is free to move up and down, and is attached to a ceiling or other object by two lengths of the same rope.
Detailed explanation-3: -Answer: There are three types of pulleys, namely, fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are those pulleys that are attached to a single point. As the name suggests that this pulley is stationary and is fixed to support like wall or ceiling and the rope/chain passes through it.
