During the construction of the LRT railroad track, hot rolled structural steel A36 of 10-m-long rails were used. The steel rails were laid on the track with a 5-mm gaps between the rails during the night when the temperature of the steel was 20°C. Determine the normal stress in the steel rails when the temperature of the steel is 40°C. E = 200 GPa and a = 11.7 x 10-6 m/(m °C)

Older railroad tracks in the U.S. are made of 12-m-long pieces of steel. When the tracks are laid, gaps are left between sections to prevent buckling when the steel termally expands. If a track is laid at 16*C, how large should the gaps be if the track is not to buckle when the temperature is as high as 50*C?
