Consider steel railroad rails, which have a thermal coefficient of linear expansion of 1.20 × 10-5 / °C. How large an expansion gap, in meters, should be left between such rails if they may reach a maximum temperature 36°C greater than when they are laid? Assume their initial length is 10.0 m

A long steel I-beam used in bridge construction has a length of 19.1 m and is made of an element which has a coefficient of linear expansion of 11.0 X 10-6 (°C)-1. The beam may be exposed to temperatures as low as -18°C in the winter and as high as 35.5°C in the summer. What is the difference in length of the beam between these two temperature extremes? (Give the absolute value of the difference. Enter your answer in mm.)

The height of the Washington Monument is measured to be 170 m on a day when its temperature is 35.0°C. What will the change in its height be on a day when its temperature falls to -4.5°C? Although the monument is made of limestone, take the thermal coefficient of expansion to be the same as for marble, which is 2.50 x 10-6/°C. (Be sure to include the appropriate sign with your answer.). Enter a number. length and temperature are always defined as final value minus the initial value. Therefore be sure to consider the cign quantities om

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.
