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 the sections to prevent buckling when the steel thermally expands.
1.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?
