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. If the origin O 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 (-1.5, 2.2, 24.6) ft and the point where the cable is attached to the end of the cross member is B (1.5, -2.8, 27.6) ft. The cable's direction is {1.00i - 1.00j - 1.00k} and it has a tension of 165lb. What is M_a ( the moment that tends to twist the telephone pole due to the tension in the cable applied at point B?)
