Q1) Three bars each made of different materials are connected together and placed between two walls when the temperature is T, = 10°C. Determine the force exerted on the (rigid) supports when the temperature becomes T, = 25°C. The material properties and cross-sectional area of each bar are given in the figure. Copper Brass Fixed Support Steel B с D 100 mm 200 mm Fixed Support 300 mm A.- 150 mm Est = 200 GPa Abr = 300 mm Er = 100 GPA Olbr=21x101/C Acu = 450 mm Ecu = 120 GPa ast=12x101/°C Qcu = 17x101/C
