H.W : The 500 kg engine is suspended from the crane boom in the Figure. Determine: 1- The resultant reactions at point D and A. 2- The resultant internal loadings acting on the cross section of the boom at point E 1.5 m A JE -1 m--1 m--1 m-

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
