In a steel railroad, the 12 meters long rails are laid with a clearance of 5 mm at a temperature of 20 degrees centigrade. The modulus of elasticity of steel is 200 GPa. a) At what temperature will the rails just touch if the coefficient of linear expansion is 11.7x10^-6/°C.? b) Determine the stress in the rails at 65 °C
