1. The problem statement, all variables and given/known data Demonstrate using free body diagrams and equations that, using the same force, a heavier load can be lifted with a rope and pulley system than with a rope alone. 2. The attempt at a solution To lift something off the ground without a pulley, the applied force must be greater than the gravitational force. With a pulley, the force you apply still must be great, but the pulley just changes the direction of the force/motion?? Thanks.
