A structure of two welded plates is fixed at point A by a ball joint, at point B by a cylindrical hinge, and at points by a supporting rod. Two forces (according to Loading Diagram number) and a couple M = 4 km are acting on the structure. Dimension a = 0.6 m. Not taking into account the deadweight of the plates, determine the reactions of the supports A, B, and C. Verification of solution and also free body diagram
