(Missed earlier postings; if no one mentioned it, the extant data
divides between wood-on-trees and commercial boards, etc.)

I did a little work on the subject a few years ago, looking at the
ratio of flexural to torsional stiffness, which meant that I measured
some E's and G's. The data apply to lengths of tree-trunks tested
within an hour of cutting - in short, to nature's normal stuff.

See Vogel, S. (1995) Twist-to-Bend ratios of woody structures. J.
Exp. Bot. 46: 981-85.

On commercial wood, the best thing I know of is a compendium...
