Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

1. A steel railroad track is laid at a temperature of 15 °F with gaps of 0.18 inch between the ends of
the rails. The rails are 34 feet long. If they are prevented from buckling, what stress will result from
a temperature of 115 °F? Coefficient of linear expansion is 6.5 x 10-6 /°F, and E = 30 x 10$ psi.
