The direction cosines of the crane’s cable are cos θx = 0.588, cos θy = 0.766, cos θz = 0.260. The y axis is vertical. The stationary caisson to which the cable is attached weighs 2000 lb and rests on horizontal ground. If the coefficient of static friction between the caisson and the ground is μs = 0.4, what tension in the cable is necessary to cause the caisson to slip?
