A uniform, 255 N rod that is 2.10 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. 1. Find W. 2. If W is now moved 20.0 cm to the right, how far must the fulcrum be moved to restore balance? 3. If W is now moved 20.0 cm to the right, in what direction must the fulcrum be moved to restore balance?
EXERCISE HINTS: GETTING STARTED I'M STUCK! A man ties one end of a strong rope 7.68 m long to the bumper of his truck, 0.534 m from the ground, and the other end to a vertical tree trunk at a height of 3.86 m. He uses the truck to create a tension of 7.73 x 10 N in the rope. Compute the magnitude of the torque on the tree due to the tension in the rope, with the base of the tree acting as the reference point. N. m
