Question

Three bars each made of different materials are connected together and placed between two walls when the temperature is 20 ℃. Determine the force exerted on the (rigid) supports when the temperature becomes 30 ℃. The material properties and cross-sectional area of each bar are given in the figure.

7. 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 exerted on the (rigid) supports when the temperature becomes T1 = 18°C. The material properties and cross-sectional area of each bar are given in Figure 7. Steel Brass Сорper Es = 200 GPa 12(10¬°)/°C abr = Epr = 100 GPa 21(10-)/°C acu = 17(10-6)/°C Ecu = 120 GPa ast = Acu = 515 mm² A = 200 mm² Apr = 450 mm² 300 mm -200 mm 100 mm Figure 7
