Bull****. Wood is a very strong material when used appropriately.


Not according to any rational analysis. It's cheap & renewable to some
extent & still has some traditional uses but in actual structural
situations it's about the worst choice. However you are certainly
entitled to put your opinion, just so long as you don't deny me the same
right.


Bull****. Wood is an EXCELLENT structural medium. Even common fir, not
a particularly hard wood, has a bending stress capacity (Fb) of
somewhere in the vicinity of 1500 psi.
