Expansion joints are used to allow for thermal expansion bridges. A steel bridge with a single expansion joint must operate between temperature extremes -50 F and 150 F, the gap in the joint is fully closed and the bridge is 100 m long. The linear expansion coefficient of steel is 12 x 10^-6 (Celcius). What is the gap at -50 F? Express your answer in centimeters.

The bridges often have expansion joints to account for the
changes in size due to temperature changes. Suppose a bridge is
supported by steel girders; the central span has a girder that is
30 m long.If the girder warms from 0∘C to 28 ∘C, by how much does its
length increase? Please include units.

In this example we see how thermal expansion can actually throw off the accuracy of a length-measuring device—namely, a tape measure. A surveyor uses a steel measuring tape that is exactly 50.000 m long at a temperature of 20 ∘C. What is its length on a hot summer day when the temperature is 35 ∘C?
