Just like torsion, in pure bending there is an axis within the material where the stress and strain are zero. This is referred to as the neutral axis. And, just like torsion, the stress is no longer uniform over the cross section of the structure – it varies. binary b - 520 mrtx 230 4x4 new priceWebNo. His suggestion is absolutely idiotic. The shear modulus of wood is just as variable as the bending strength and much less likely to be published, which means even if you have the shear modulus, it wouldn't do any good to resolve which bending strength to use.
