Pulley systems are simple machines used to lift heavy burdens. Image on the left describes 2-to-1 pulley. With this pulley, it takes roughly half of the force to lift the weight. But to lift the weight by 1 meter, you must take 2 meters of the slack as illustrated by arrows and colored parts of the rope. | |||
