An aluminum rod is 30.0 cm long and a steel rod is 90.0 cm long when both rods are at a temperature of 15°C. Both rods have the same diameter. The rods are joined end-to-end to form a rod 60.0 cm long. The coefficients of linear expansion of aluminum and steel are 24 x 10-5 K-1 and 1.2 x 10-5 K-1, respectively. The temperature is raised to 70° C. The increase in the length of the joined rod, in mm, is closest to:

Older railroad tracks in the U.S. are made of Part A 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. 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? The coefficient of linear expansion of soft steel is 1.1 × 10-5 °C-1.
