The bent rod is supported by a ball-and-socket joint at B and the cables attached to points A and C as shown in the figure. The cable at C is in z-direction. The rod is subjected to two forces, F applied at C and P applied at D. Force P is along line AD. Determine the tensions in the two cables, the magnitude of force P, and the components of the support reaction at B. 100 F = {-20i+30j} N 400 300 Dimensions in mm
