Problem 1: Three vertical posts AD, BE, and CF are held between two horizontal rigid plates. Posts AD and CF are made of steel (Es = 200 GPa) and have cross sectional areas of 1000 mm² each. Post BE is made of aluminum (Ea = 73.1 GPa) and has a cross sectional area of 1500 mm². Initially, there is a small gap of 0.1 mm between BE and the top horizontal plate. Then a vertical force of P = 410 kN is applied, which is more than sufficient to close the gap completely. A D -0.5 m- P -0.5 m 0.4 m F Determine the normal stresses in posts AD, BE, and CF (both magnitude and sign).
