A steel beam used in the construction of a brídge is 9.2 m long at 20 °C. On a hot summer day, the temperature increases to 40 °C What is the change in length due to línear expansion? The coefficient of linear expansion for steel is 11 x 10-/°C.

At a temperature of 22.00°C the hole in a steel plate has a diameter of 1.030 cm. If a steel rod with a diameter of 1.037 cm has to just slip through this hole, to what temperature should the plate be heated? The coefficient of area expansion of steel is 24 x 10-6/°C. °C

A steel pole is 660 m long on a cold day when the temperature is 32.0 °F.  How much longer (in cm) is the pole on a hot day when the temperature is 103 °F? (The linear expansion coefficient of steel is 12 × 10–6 °C–1)  ΔL =    cm

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.

A steel rod and a bronze rod are heated. At zero degree Celsius, the steel rod has a Ls  and the bronze rod has a length of Lb. When the rods are heated or cooled, the difference between their length stays constant at 5.00 cm. Determine the values of Ls and Lb.

A metal rod has a starting length of 240 cm. When the temperature changes from 25 °C to 110 °C, the length of the rod changes 0.115 cm. What is the linear expansion coefficient of the rod?
