What are the mechanical properties of wood?

The mechanical properties of wood include strength in tension and compression (as measured in axial and transverse directions), shear, cleavage, hardness, static bending, and shock (impact bending and toughness).

What are the 5 physical properties of wood?

The main physical properties of wood include: color, luster, texture, macro-structure, odor, moisture, shrinkage, internal stresses, swelling, cracking, warping, density, sound – electro – thermal conductivity.

What are the two factors that determine the mechanical strength of wood?

Factors Influencing Wood Strength As we know, the strength of wood is different in each direction (i.e. tangential vs radial). Other factors that can influence the strength of a given piece of wood include: specific gravity, moisture content, knots, and slope of grain.

Relationship between Mechanical Properties and Anatomical Structure of Wood Property n A90/A0 Tensile strength 1.5–2 0.04–0.07 Compression strength 2–2.5 0.03–0.40 Bending strength 1.5–2 0.04–0.10 Modulus of elasticity 2 0.04–0.12

What are the three moduli of elasticity of wood?

The three moduli of elasticity, which are denoted by EL, ER, and ET, respectively, are the elastic moduli along the longitudinal, radial, and tangential axes of wood. These moduli are usually obtained from compression tests; how- ever, data for ERand ETare not extensive. Average values of

Why are mechanical property values based on speci-mens with interlocked grain?

Some mechanical property values in Table 4–5 are based on speci- mens with interlocked grain because that is a characteristic of some species. The presence of interlocked grain alters the relationship between bending strength and compressive strength of lumber cut from tropical hardwoods.
