1.	What is movable pulley and fixed pulley
Answer» Answer: A pulley is a mechanical device that can be USED to LIFT heavily objects more easily. ... A fixed pulley's wheel and axle STAY in one place. 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. Examples of movable pulleys include construction cranes, modern elevators, and some types of weight lifting machines at the GYM.
