Mechanical <strong>Properties</strong> Factors Affecting Strength Defects that disturb fiber continuity and direction, most notably knots, adversely affect the strength of individual pieces. A 2” knot on the edge of a 2 X 8 reduces its strength by 43% . A 2” knot in the center of a 2 X 8 reduces its strength by only 24% .
