Question

Figure 3 of 3 > An old wooden telephone pole with a single cross member was blown off center during a recent storm. To temporarily stabilize the telephone pole, a repair crew has attached a cable from the end of the cross member to an eye-ring stake anchored in the ground. (Figure 3) If the origin of a coordinate system is placed where the pole meets the ground, the point where the cross member is attached to the pole Is A 0.85, 1.10.12.2) m and the point where the cable is attached to the end of the cross member is B(-0.85, -1.40,13.7) m. The cable's direction is 1.00 -1.00 - 1.00k) and it has a tension of 975 N. What is M., the moment that tends to twist the telephone pole due to the tension in the cable applied at point B?
