 DIY pulley block crane kids diy physics learning resources

A pulley is a kind of simple mechanic device which is used to lift heavy materials and save energy. Pulley can be divided into fixed pulley and movable pulley. The center axle of a fixed pulley doesn’t change. The center axle of a movable pulley is moveable. Utilizing fixed pulley can’t save force nor save distance but can chance the direction of force. Utilizing movable pulley can save half force but can’t change the direction of force and cost twice distance. While assemble fixed pulleys and movable pulleys together and form a pulley blocks can both save force and change the direction of force.
