The rails of a railroad track are welded together at their ends (to form continuous rails and thus eliminate the clacking sound of the wheels) when the temperature is 60^∘ F. What compressive stress σis produced in the rails when they are heated by the sun to 120^∘ F if the coefficient of thermal expansion α=6.5 ×10^-6 /^∘ F and the modulus of elasticity E=30 ×10^6 psi ? | Numerade

One of the most pleasant experiences riding the Cumbres & Toltec Scenic Railroad is listening to the “clickity-clack” the train makes as it passes over the rails. This is because, unlike Amtrak or urban railroads, the rails on the C&TSRR are not welded together. Modern railroads use Continuous Welded Rails (CWR) where each rail length is welded together to make one continuous rail that can be miles long. This creates a smoother ride, but trains on these rails make more of a “whining” noise than
