Depends on the load, but I'm assuming you mean under deflection. If so, the
square post is stronger as it has a larger surface area associated to the
top and bottom chords. This assumes all corners have been broken for stress
concentration relief. If you mean a load under tension, it's strictly a
matter of cross sectional area (assuming a consistent modulus of elasticity
across the section) thus the square section again would win...as it would
under compression.

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.
