Abstract. Wood has several unique, independent mechanical properties. Physical and mechanical properties of wood have a large number of values determined
The strength of wood increases as its density increases. The shearing strength of wood is 10-15% of its tensile strength in the direction of the grain. Shearing
The strength of wood varies between different species, but also within a species, and properties (parallel and perpendicular to grain) and shear properties.
Owing to the fact that the tensile strength of wood is from two to nearly four times the compressive strength,
Flexural strength testing of Wood is accomplished with three point bend fixtures. Wood products are a common engineering material used in the construction
