Hankinson Formula


The bearing strength of wood depends on the direction of grain with respect to the direction of the applied load. Wood is stronger in compression parallel to grain than in compression perpendicular to grain. The variation in strength at various angles to grain between 0 and 90 degrees is determined by the Hankinson Formula
