WebBending results from a couple, or a bending moment M, that is applied. 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. csshl championships 2023

Web10 mrt. 2024 · The bending strength of a piece of wood is measured by applying a force perpendicular to the wood’s grain. In this configuration, the strength of a wood board is maximized to incur a force. The reason for this is that wood fibers run through the grain in elongated strands.
