Reference no: EM131011187

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. The cross- sectional area of each rail is 5.90 in^2 .

Part A Determine the required gap delta so that the rails just touch one another when the temperature is increased from T1 = -26 degree F to T2 = 90 degree F? Express your answer to three significant figures and include the appropriate units.
