With each part being the same length, and a cross-sectional area of 5.25 in^2, being made of A992 steel, when the temp goes from -10F to 100F how large should the gap be so the rails don't touch?
Determine the stress if temp rose to 110F based on gap size
Determine if rails would fail with max shear or normal stress
