1. The problem statement, all variables and given/known data A man is trying to lift a box using three pulleys and two peices of rope. Each pulley can turn without friction and has negligible mass.The first rope, attached to the man, paases down under pulley A, up over pulley B and down to the frame of pulley C. The second rope is tied to the frame of pulley A and passes down under pulley C and up to the ceiling. If the box weighs 60N with what force must the man pull on the first rope to lift the box? 2. Relevant equations 3. The attempt at a solution To start off i know i have to draw an FBD. but would there be 3 FBDs for the pulleys or just one for the mass?
