The 40-ft-long A-36 steel rails on a train track are laid with a Part A small gap between them to allow for thermal expansion. The cross-sectional area of each rail is 5.00in2. Determine the required gap δ so that the rails just touch one another when the temperature is increased from T1​=−18∘F to T2​=9∘F. (Figure 1) Express your answer to three significant figures and include the appropriate units. Part B Using this gap, what would be the axial force in the rails if the temperature were to rise to T3​=110∘F ? Express your answer to three significant figures and include the appropriate units. Figure 1 of 1 X Incorrect; Try Again; 5 attempts remaining
