5. Differential pulley - Wikipedia

   en.wikipedia.org/wiki/Differential_pulley

   The two sections of chain carrying the single pulley exert opposing and unequal torques on the connected pulleys, such that only the difference of these torques has to be compensated manually by pulling the loose part of the chain. This leads to a mechanical advantage: the force needed to lift a load is only a fraction of the load's weight. At ...
