A 13 in length of aluminum tubing (with E = 11.4 x 106 psi and  = 12 x 10-6 /deg F) having a cross-sectional area of 1.6 in2 is installed with “fixed” ends so that it is stress-free at 70 deg F. In operation, the tube is heated throughout to a uniform 500 deg F. Careful measurement at the higher temperature indicates that the fixed ends separate to 13.008 in. What loads are exerted on the ends of the tube, and what are the resultant stresses?

A rigid bar is supported by two copper ro ds and the gap (A) between the aluminu m rod and the bar is 1.50 mm. If the temp erature for all materials is increased by 4 0 degrees Celsius, will the aluminum rod touch the rigid bar or not? Prove your ans wer by stating computed data. Disregard the weight of the rigid bar. For each copper bar, A = 500 mm^2, E = 120 GPa, and a = 1 6.8 μm/(m. C). For the aluminum bar, A = 400 mm^2, E = 70 GPa, and a = 23. 1 μm/(m.
