Pulleys functions by reducing the total work done, to increase the power of the work. For example: in a 2x pulley (the pulley system provided in the kit), each 1 ft pull of the rope, only moves the pulley ½ ft. Pulleys are used for many activities. Sailor use pulleys to pull in the boom and sail. The Egyptians used pulleys to pull the large stone blocks up the sides of the

Basic Pulley Mechanisms : 17 Steps (with Pictures

Most pulley systems are friction based, which means that if the one side of a belt and pulley system jams,the belt can slip against the pulley if it needs to. Although this may sound bad, it is actually beneficial because it prevents the system from stalling out the motor by taking on too much torque. Band saws are a great example of this. The blade of the band saw is a large
