Which pulley system can make work easier?
Asked by Wiki User
A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.
