Question:

Assuming that the 120-kip load is removed from the truss in Figure P9.24, compute the reactions and bar forces if the temperature of bars $A B$ and $B C$ increases $60^{\circ} \mathrm{F}$; the coefficient of temperature expansion $\alpha=6 \times 10^{-6}$ (in./in.) $/{ }^{\circ} \mathrm{F}$.
