A uniform, 257-{\rm N} rod that is 2.05 {\rm m} long carries a 225-{\rm N} weight at its right end and an unknown weight W toward the left end (see the figure ). When W is placed 46.5 {\rm cm} from the left end of the rod, the system just balances horizontally when the fulcrum is located 72.7 {\rm cm} from the right end. Part A: Find W Part B: If W is now moved 26 cm to the right, how far must the fulcrum be moved to restore balance?
