The center post B of the assembly has an original length of 124.7mm, whereas posts A and C have a length of 125 mm. If the caps on the top and bottom can be considered rigid, what is the magnitude of the sum of the forces exerted by bars A, B, and C on the top plate? The posts are made of aluminum and have a cross-sectional area of 400 mm2. Eal=70 GPa. Answer should be in kN.
