Pulleys are simple machines that make lifting loads easier. Ropes and pulleys allow people to lift objects much higher than they could with just their arms, provided there is a supporting structure to hang the pulley from and the rope is long enough. Using a system of multiple pulleys makes it easier to lift heavy loads. This course focuses on compound pulley assemblies called block and tackles.
