A 250-mm length of steel tubing (with properties of E = 207 x 109 Pa and α = 12 x 10-6 per degree Celsius) having a cross-sectional area of 625 mm2 is installed with "fixed" ends so that it is stress-free at 26°C. In operation, the tube is heated throughout to a uniform 249°C. Careful measurements indicate that the fixed ends separate by 0.20 mm. What loads are exerted on the ends of the tube, and what are the resultant stresses?
