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. (Eigure 3) 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(-1.50, 2.10, 23.9) ft and the point where the cable is attached to the
end of the cross member is B(-1.50,-2.90, 26.9) ft. The cable's direction is
(1.00-1.00-1.00k) and it has a tension of 145 lb. What is M₁, the moment that tends to
twist the telephone pole due to the tension in the cable applied at point B?
Express your answer numerically in pound-feet to three significant figures.
