In practical terms, the number itself isnt all that meaningful, but it becomes useful to use in comparison with other woods. Medium to coarse texture, with moderate natural luster. The only difficulties typically arise if the wood is being stained, as it can sometimes give blotchy resultsusing a sanding sealer prior to staining, or using a gel-based stain is recommended. Common Uses: Boatbuilding, docks, decking, posts, fishing rods, pool cues, and other turned wood items. The Youngs modulus of elasticity is the elastic modulus for tensile and compressive stress in the linear elasticity regime of a uniaxial deformation and is usually assessed by tensile tests. For instance, Ipe is known to have excellent strength properties among imported species, and has a crushing strength of 13,510 lb f /in 2 (93.1 MPa). Values for wood adjusted to 12% moisture content may be assumed to be approximately of the same magnitude. They are real-world examples that parallel totally separate wood tests (modulus of rupture, modulus of elasticity, and crushing strength, respectively). For example, air-dried wood with average moisture content of 12-13 percent will have higher strength properties than that of wood with 20 percent moisture content. Size.
