The steel bar AB has a 3 8 3 3 8-in. square cross section
Chapter 10, Problem 10.41(choose chapter or problem)
The steel bar AB has a \(\frac{3}{8} \times \frac{3}{8}-\mathrm{in}\) square cross section and is held by pins that are a fixed distance apart and are located at a distance e = 0.03 in. from the geometric axis of the bar. Knowing that at temperature \(T_{0}\) the pins are in contact with the bar and that the force in the bar is zero, determine the increase in temperature for which the bar will just make contact with point C if d = 0.01 in. Use \(E=29 \times 10^{6} \mathrm{psi}\) and a coefficient of thermal expansion \(\alpha=6.5 \times 10^{-6} /{ }^{\circ} \mathrm{F}\).
