Strategy

Use the equation for linear thermal expansion to calculate the change in length , **Î”L** . Use the coefficient of linear expansion, **Î±** ,for steel from Table 13.2, and note that the change in temperature, **Î”T** , is **55ÂºC**

**(b)** convert the change in temperature if Kelvin and Fahrenheit degrees. *****this section is not included in the Reference material*

Discussion

Although not large compared with the length of the bridge, this change in length is observable. It is generally spread over many expansion joints so that the expansion at each joint is small.
