Pine Strength

This could have gone in with the discussion on the 2×4 contest for Jan ‘08 but I wanted to get a bit more clear about my individual question.

Does anyone know whether long-grain pine wood is strong enough at 1/2in. for most box building purposes?

Okay, that may be vague or confusing or both…

I know 3/4in. is good for plywood. I’m curious as to if I would be asking too much at 1/2 in. I would be resawing to 1/2in. thickness for my project as planned right now and I need a little guidance before I get to cutting and waste a bunch of time.

Any thoughts?
