not sure if I am in the right place or not but nevertheless need some help
I am trying to figure the correct steel to use for sign support. I am trying to determine if a 5 x 5 inch with .25 wall is as strong or stronger than a 6 x inch tube with a 3/16 wall. Can't find any formulas to help me out. thanks

Check out the AISC Steel Construction Manual 14th edition.
It usually governs for steel design/capacities in the public works arena.

The evaluate the square tube vs. round tube made of the same material, you need to look at their second moment of area also (somewhat erroneously) known as the beam moment of inertia.
