The horizontal steel rod, 2.5 m long and 1200 mm² in cross-sectional area, is secured between two walls as shown in the figure. If the rod is stress-free at 20°C, compute the stress when the temperature has dropped to -20°C. Assume that (1) the walls do not move and (2) the walls move together a distance 0.5mm. Use α= 11.7x10-6/°C and E=200GPa.
