I found this question in another group (misc.rural)...
Which is stronger, a round post or square post? Assume the posts are
both made from the same wood and are both equivalent in width.

As another poster indicated, assuming we're talking about bending, the
moment of intertia of a square cross-section is L^4/12.

I had a moment of inertia shortly after finishing my lunch, but then
I went back to work.
