A rod is composed of three segments, as shown in the figure. Compute the stress induced in each material by a temperature drop 30 °C if (a) the walls are rigid and (b) the walls spring together by 0.3mm. Assume E,=70 GPa, a,=23.0 µm/m-°C, A=1200 mm², Es=83 GPa, a,=18.9µm/m-°C, A=2400 mm², E=200 GPa, a,=11.7 µm/m-°C and A=600 mm². 800 mm 500 mm 400 mm Bronze Aluminum Steel A=1200 mm² E=70 GPa A=2400 mm? A=600 mm² E=83 GPa E=200 GPa
