| Moisture Content: Weight of moisture in a piece of wood shown as a percentage of its oven dry weight. |
Specific Gravity: Ratio of density of wood to that of water. |
Modulus of Rupture: The maximum load-bearing capacity of a wood in bending and proportional to maximum movement borne by a specimen. |
Modulus of Elasticity: A measurement designed to show the ability of a wood to recover from deformations produced by low stress once the loads are removed. |
Compression Parallel to Grain: Maximum measurement of stress that a parallel-to-grain specimen (with a ratio of length to least dimension less than 11) of wood is able to withstand. |
Shear Parallel to Grain: Wood's ability to resist slipping of one internal part upon another part along the grain. |
Density: Weight of the wood per cubic foot. Determines the strength of the wood, varies depending on species. |
