A uniform, 255-N rod that is 2 m long carries a 225-N weight at its right end and an unknown weight toward the left end as shown in Figure 1. When W is placed 50 cm from the left end of the rod, the system just balances horizontally when the fulcrum is located 75 cm from the right end. a. Find W. b. If W is now moved 25 cm to the right, how far and in what direction must the fulcrum be moved to restore balance?
