A steel railroad track has a length of 24 m when the temperature is 8◦C. What is the increase in the length of the rail on a hot day when the temperature is 36 ◦C? The linear expansion steel is 11 × 10−6 (◦C)−1. Answer in units of m. 004 (part 2 of 2) 10.0 points Suppose the ends of the rail are rigidly clamped at 8◦C to prevent expansion. Calculate the thermal stress in the rail if its temperature...

Given a steel railroad track which was installed at 30 F. Let E
= 29 x 10^6 psi and α = 6.5 x 10^-6 / F
If the temperature reaches 125 F,
a) Find the normal stress in the rails which are welded together
to form a continuous track.
b) Find the normal stress in the rails assuming the rails are 39
ft. long with 1/4" gap between them
