A D -0.5 m- 400 KN ?AD, ?CF, ?BE = B E -0.5 m- C 0.4 m CL F The assembly consists of two posts AD and CF made of A-36 steel and having a cross-sectional area of 1000 mm2, and a 2014-T6 aluminum post BE having a cross-sectional area of 1700 mm2. If a central load of 400 kN is applied to the rigid cap, determine the normal stress in each post. There is a small gap of 0.09 mm between the post BE and the rigid member ABC. (Figure 1)
