Problem 49P

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 (?Fig. P11.47?). When W is placed 50.0 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. (a) Find W. (b) If W is now moved 25.0 cm to the right, how far and in what direction must the fulcrum be moved to restore balance?

Step-by-Step Solution:

Solution to 49P Step 1 of 3 The rod is horizontally balanced. The fulcrum at 0.75m from the right end applies a force normal to the rod. The weight of the rod is situated at the centre of mass which is at the centre of the uniform rod. Step 2 of 3 Free body diagram, (a) 0.75W+225(0.25)-255(0.75)=0 0.75W=-225(0.25)+255(0.75) W=140N upwards
