A 15 m tall utility pole is located at a 40° bend in a set of power lines. The tension in each line is 15 kN, and due to sag of the lines, the tension forces act along directions 10° below horizontal. A guy wire has been installed, as shown in the photo and the top-view sketch, to keep the pole upright. What should be the tension in the guy wire to minimize the magnitude of the moment reaction required from the ground at the bottom of the pole? With that tension, what are the reaction forces and moments required at the ground? Assume that the forces from the guy wire and all incoming and outgoing lines act at a single point on the top of the pole itself.
