80. When a wood shelf of mass 6.6 kg is fastened inside a slot in a vertical support as shown in Fig. 9–92, the support exerts a torque on the shelf. (a) Draw a free-body diagram for the shelf, assuming three vertical forces (two exerted by the support slot-explain why). Then calculate (b) the magni- tudes of the three forces and (c) the torque exerted by the support (about the left end of the shelf). - 32.0 cm 3.0 cm FIGURE 9-92 2.0 cm Problem 80.

Check Your Understanding A large ocean-going ship runs aground near the coastline, similar to the fate of the Costa Concordia, and lies at an angle as shown below. Salvage crews must apply a torque to right the ship in order to float the vessel for transport. A force of 5.0105Nacting at point A must be applied to right the ship. What is the torque about the point of contact of the ship with the ground (Figure 10.36)?
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
