Question
Three bars each made of different materials are connected together and placed between two walls when the temperature is 7, 12°C. Determine the force exerted on the (rigid) supports when the temperature becomes T 18 C. The material properties and cross-sectional area of each bar are given in the figure.
•4-69. Three bars each made of different materials are Brass E- 100 GPu a = 12(10*)C - 21(10 ")/C a= 17(10)/C Steel Copper connected together and placed between two walls when the temperature is T = 12 C. Determine the force exerted on the (rigid) supports when the temperature becomes T; = 18'C. The material properties and cross-sectional area of each bar are given in the figure. E = 200 GPa = 120 GPa Au - 515 mm A = 200 mm A450 mm 300 mm- -200 mm 100 mnt
