Pulleys can multiply the force you apply. Example: I pull down on a pulley with TWO Pulleys THREE supporting Strands and the force is Multiplied by a factor of TWO, but you have to pull TWICE the length of Rope as the Distance the Object is Raised. Therefore you can LIFT more WEIGHT than you normally could.
The relationship of Supporting Strands to the Force Multiplier is:
(the number of Supporting Strands) - 1
So a Pulley system with 5 Supporting Strands with Multiply YOUR input Force by 4 times. This type of System is referred to as "Block and Tackle".
