a) Replace the loading system acting on the post by an equivalent resultant force and couple moment at point A. b) Replace the loading system acting on the post by an equivalent resultant force and couple moment at point B. c)Replace the loading acting on the beam by a single resultant force. Specify where the force acts, measured from C.

Determine the distance between points D and B after the loads are applied. Consider that the bars have a cross-sectional area of 50 mm2, and E = 200 GPa. The size of the couplings B, C, and D is 0.00001 mm.
