Chapter 6, Problem 55TS

Suppose the $1300\text{-meter}$ steel span of the Golden Gate Bridge had no expansion joints (as in Figure 6.19). Show that an increase in temperature of $20°\text{C}$ would make the bridge nearly $0.3\text{ m}$ longer ( $\alpha$ for steel is $11\times {10}^{-6}/°\text{C}$).
