1. Two tractors pull on the three with the forces shown. Represent each force as a Cartesian vector and then determine the magnitude and coordinate direction angles of the resultant force. Refer to Figure 1. 2. Collar A is connected as shown to a 50-lb load and can slide on a frictionless horizontal rod. Determine the magnitude of the force P required to maintain the equilibrium of the collar when (a) x = 4.5 in., (b) x = 15 in. Refer to Figure 2. 3. A sailor is being rescued using a boatswain's chair that is suspended from a pulley that can roll freely on the support cable ACB and is pulled at a constant speed by cable CD. Knowing that a 5 30" and b 5 10" and that the combined weight of the boatswain's chair and the sailor is 900 N, determine the tension (a) in the support cable ACB, (b) in the traction cable CD. Refer to Figure 3. 20 in. Fa- 150 Fac = 100 lb 30 ft 50 lb 20 ft 10 f- Figure. 1 Figure. 2 Figure 3.
