  1. In-Class Problem 3-1A bulldozer has gotten stuck in the mud. Cables from two recovery vehicles are attached to the bulldozer’s tow hook, and these cables exert the forces shown below. Calculate the resultant force on the tow hook.

  2. In-Class Problem 3-2After the bulldozer is pulled out of the mud, its engine must be removed from the vehicle for repair. The engine has a mass of 20 slugs. Several mechanics are pulling on one rope with F1=500 lb of force at the angle shown below. How much force, F2, and at what angle, q, must the other mechanics pull on the other rope in order to suspend the engine above the ground?
