At room temperature (200C) a 0.5-mm gap exists between the ends of the rods shown. At a later time when the temperature has reached 1400C, determine (a) the normal stress in the aluminum rod, (b) the change in length of the aluminum rod. (c) If the temperature is allowed to go up continuously, which rod would fail first? At what temperature would failure occur? Given the ultimate stress (in compression) for steel is 500 MPa for steel and 350 MPa for aluminum (Typo in figure: Coefficient of thermal expansion for aluminum is 23 x 10-6/0C). 0.5 mm 300 mm - 250 mm B Aluminum Stainless steel A = 2000 mm E = 75 GPa a = 23 × 16-°C A = S00 mm E = 190 GPa a = 17.3 x 10-6/°C
