Figure 1 below shows a thin uniform rod OA of length 2m and weight 40N that rests on the intersection of three walls at O and is supported by two cables AB and AC attached to the walls at B(0,2.5, 1.5) and C(1, 2.5, 0), where the coordinates are in meters. Find the coordinates of A if the cables are each of length 2 meters and hence find the tensions in the cables. Figure 1 A. B.
