Web31 Oct 2024 · In general, knots have a greater effect on strength in tension than compression; in bending, the effect depends on whether a knot is in the tension or … Compression of wood and wood-based materials plays an important role in almost any construction projects. If the compression strength or bending strength of a 2-inch by 4-inch beam is not known, deflection due to bearing a load may cause significant deformation, which could even lead to its failure during service … See more In contrast to metals and plastics, wood is an orthotropic material, meaning its properties will be independent in three directions – longitudinal, tangential and radial, as illustrated in … See more In the case of bending a beam, we are dealing with modulus of elasticity (MOE) and modulus of rupture (MOR) to evaluate its load resistance. While MOE is a measure of the stiffness of a body, MOR is related to maximum … See more Detailed information about mechanical properties of wood and wood products also can be found in the following literature: Wood Handbook (1999). Wood as an engineering … See more The moisture content of wood also is an important parameter influencing almost all mechanical properties. Strength properties of wood increase with its decreasing moisture content. For example, air-dried wood with average … See more
