Pulley is a mechanical component that helps transfer motion and power through a wheel turned. Pulley is the most used simple machine wherever we go in everyday life. We use pulleys to reduce the force needed to move or pull heavy objects. It is a very cost-efficient, simple machine. The best thing about this system is that there is no noise. The pulley is relatively safe as we are far away from the heavy object. Pulley requires less maintenance than any other machine. There are several types of it. The most commonly used is the movable pulley. There are also compound pulleys, cone pulleys, and fixed pulleys.
