The 40-ft long A-36 steel rails on a train track are laid with a small gap between them to allow for thermal expansion. Determine the total required gap, 2*6, so that the rails just touch one another when the temperature is increased from T1 -20°F to T2 90 °F. If the rails were installed at -20 °F with this gap, what would be the axial force in the rails if the temperature were to rise to T3 = 110 °F....
