An old wooden telephone pole with a single cross member wasblown off center during a recent storm. To temporarily stabilizethe telephone pole, a repair crew has attached a cable from the endof the cross member to an eye-ring stake anchored in the ground.(Figure 3) If the origin O of a coordinate system is placed wherethe pole meets the ground, the point where the cross member isattached to the pole is A(−2.00,1.80,23.4)ft and the point wherethe cable is attached to the end of the cross member isB(−2.00,−3.20,26.4)ft. The cable's direction is {1.00i−1.00j−1.00k}and it has a tension of 195 lb . What is Ma, the moment that tendsto twist the telephone pole due to the tension in the cable appliedat point B?
