(20%) Problem 4: A fence post of mass m = 8 kg supports a fence with three lengths of barbed wire. The bottom wire is a distance d-0.35 m from the ground and each wire is a distance 0.35 m above the previous one. Each of these three wires has the tension on it. For this problem, assume that the force exerted by these wires is purely horizontal. An additional guy wire is used to keep the pole upright with a tension of F= 460 N. The guy wire attaches to the post at a point h = 0.81 m above the ground and makes an angle of 0-55 with respect to the horizontal. 25% Part (a) Choose the correct free body diagram.
