A uniform, 255 N rod that is 1.90 mm long carries a 225 N weight at its right end and an unknown weight W toward the left end (Figure 1). When W is placed 60.0 cmcm from the left end of the rod, the system just balances horizontally when the fulcrum is located 75.0 cmcm from the right end. Find W. Express your answer with the appropriate units.   If W is now moved 20.0 cmcm to the right, how far must the fulcrum be moved to restore balance? Express your answer with the appropriate units.   If W is now moved 20.0 cmcm to the right, in what direction must the fulcrum be moved to restore balance?
