A steel rails have a small gap between them to allow thermal expansion. If the length of each steel rail is 40 feet, determine the following: a. The required gap so that the rails just touch one another when the temperature is increased by 110°F. b. What would be the axial force in the rails if the temperature were to rise 110°F? Use a = 6.6 × 10-6/°F and E = 29 × 10³ksi. | 8+ A = 5.10 in?

Transcribed Image Text:A steel rails have a small gap between them to allow thermal expansion. If the length of each steel rail is
40 feet, determine the following:
a. The required gap so that the rails just touch one another when the temperature is increased by 110°F.
b. What would be the axial force in the rails if the temperature were to rise 110°F?
Use α =
6.6 x 10-6/°F and E = 29 x 103ksi.
A = 5.10 in?
