All members of the aluminum truss have the same cross-sectional area. Member AD and CD are made of steel and member BD is made of aluminum. If the truss is stress-free at 20 °C, determine the stresses in the members at 80 °C. For steel, 11.7 x 10-6/°C and E = 200 GPa and for aluminum, alpha = 23.1 x 10- 6/°C and E = 70 GPa. alpha = %3!
