For typical metals, modulus of elasticity is in the range between 45 GPa (6.5 x 10 6 psi) to 407 GPa (59 x 10 6 psi). Modulus of elasticity is also a measure of material's stiffness or resistance to elastic ...

WebA good indicator of a wood’s strength is its density — the weight for a given volume. This is measured by its specific gravity — the weight of a volume of wood divided by the weight of the same volume of water. Generally, the higher the ratio, the denser and stronger the wood. This is not always the case, but specific gravity is a useful ...
