Pressure Vessels

The term pressure vessel refers to a closed container that contains gas or liquid at a different pressure than environment pressure. The pressure vessels have a wide scale of applications in our day-to-day lives and other industrial places. Some common examples of pressure vessels are gas cylinders, autoclaves, compressor vessels, etc.

Question

1) Steel railroad reels 10 m long are laid with a clearance of 3 mm at a temperature of
15°C. At what temperature will the rails just touch? What stress would be induced in the
rails at that temperature if there were no initial clearance? Assume a = 11.7 um/(m-°C)
and E = 200 GPa.
