2. Three bars each made of different materials are connected together and placed between two walls when the temperature is T₁ = 12°C. Determine the force 1 exerted on the (rigid) supports when the temperature becomes T2 = 18°C. Material and geometric properties are as shown. (Just set up the equation, you don't need to solve for the final answer) αst= Steel Brass Est = 200 GPa 12(10-6)/°C Ebr = 100 GPa Copper Ecu=120 GPa abr 21(10-6)/°C αcu = 17(10-6) Acu = 515 mm² Ast=200 mm2 Abr = 450 mm² 300 mm- 200 mm- 100 mm
