Question:

The center post  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, determine the average normal stress in each post. The posts are made of aluminum and have a cross-sectional area of 400mm2.Modulus of elasticity is Eα = 70GPa
