Knots materially have an effect on cracking and warping, ease in Functioning, and cleavability of timber. They're defects which weaken timber and lower its price for structural reasons exactly where toughness is an important consideration. The weakening outcome is considerably more severe when timber is subjected to forces perpendicular into the grain and/or tension than when less than load alongside the grain and/or compression. The extent to which knots have an affect on the energy of a beam relies upon on their placement, size, variety, and situation. A knot about the higher facet is compressed, whilst one particular on the reduced aspect is subjected to stress.
