    2. b)

      Rails of 12 m length each are laid on the track in the morning when the atmospheric temperature was 12ºC, a gap of 3 mm was kept between two consecutive rails. i) At what maximum temperature the rails will remain stress-free. ii) If temperature is raised further by 10ºC than the atmospheric temperature, what will be the magnitude and stress induced in the rails. Take E as 200 GPa and  = 12 × 10 –6 /ºC.
