The horizontal steel rod 2.5m long and 1200mm^2 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 of 0.5mm. Use E=200GPa, α=11.7x10^-6/°C.
