The assembly shown in figure (5) consists of two posts AD and CF made of a steel (Ast = 1000 mm2,
Est = 200 Gpa) and one post BE made of aluminum (AAI = 1500 mm?, EAI = 73.1 Gpa). If a central
load of 459 kN is applied to the rigid cap, determine the normal stress in each post. There is a
small gap of 0.1 mm between post AD and post CF with the rigid member ABC.
