Steel railroad rails 10 m long are laid with end-to-end clearance of 3 mm at a temperature of 15°C. (a) At what temperature will the rails just come in contact? (b) What stress would be induced in the rails at that temperature if there were no initial clearance? Use a = 11.7 x 10-6 PC and E = 200 GPa.
