Specific gravity of balsa wood

WebA gallon of water is 3.786 liters or 3785.41 milliliters to me more exact. 1 mL of water at 4 degrees Celsius or 39.4 degrees F, it’s most dense temperature, is exactly 1.0 gram. Therefore a gallon of water at standard temperature is 3785.41 grams divided by 453.59 grams per pound which is 8.345 pounds per gallon. WebMean air dried specific gravity is 0.53 (ranged from 0.487 to 0.518), while mean oven dried specific gravity is 0.424 (ranged from 0.410 to 0.437). Specific gravity among logs significantly different, and it tends to decrease from bottom to higher in melina stem.

WebIn general, depending on the species, wood has MOE and MOR values of 800,000–2,500,000 psi and 5,000–15,000 psi, respectively. If a Red Oak with an approximate MOE value of 2,000,000 psi is used to make the bookshelf mentioned above, its deflection deformation will be less than that of Aspen, which has a lower MOE. 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.
