Problem 11.51 - Enhanced - with Feedback
A uniform, 255 N rod that is 2.00 m 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 cm from the left end of the
rod, the system just balances horizontally when the fulcrum is
located 75.0 cm from the right end.
Part A
