Question: For the tree of Prob. 2.73, knowing that the tension in cable AC is 980 lb and that the resultant of the forces exerted at

For the tree of Prob. 2.73, knowing that the tension in cable AC is 980 lb and that the resultant of the forces exerted at A by cables AB and AC lies in the yz plane, determine (a) The tension in AB, (b) The magnitude and direction of the resultant of the two forces. Problem 2.73: To stabilize a tree partially uprooted in a storm, cables AB and AC are attached to the upper trunk of the tree and then are fastened to steel rods anchored in the ground. Knowing that the tension in cable AB is 950 lb, determine

(a) The components of the force exerted by this cable on the tree,

(b) The angles θx, θy, and θz that the force forms with axes at A which are parallel to the coordinate axes.
