The assembly has the diameters and material indicated. If it fits securely between its fixed supports when the temperature is T1=70℉, determine the average normal stress in each material when the temperature reaches T1=110℉. (Young’s Moduli are 10.6×10^6 kip/in^2, 15×10^6 kip/in2, and 28×10^6 kip/in^2 for aluminum, bronze, and steel, respectively. The coefficients of thermal expansion are 12.8 μstrain/°F, 9.60 μstrain/°F, 9.60 μstrain/°F for aluminum, bronze, and steel, respectively.)
