Algebraic Physics Question: Older railroad tracks in the USA are made of 12 meter long pieces of steel. When the tracks are laid, gaps are left between the sections to prevent buckling when the steel thermally expands. If a track is laid at 16 degrees C, how large should the gaps be if the track is not to buckle when the temperature is as high as 50 degrees C?
