WebThe wood’s strength cannot be fully used up around the fracture limit, so lower levels of stress have to be chosen. ... In terms of strength, pine and spruce are treated the same, and they are normally judged to have the same strength values: Compression strength is high in the fibre direction, with the grain, but much lower, around 1/6 ... WebTensile strength also depends on the density of the wood: for example, the tensile strength of the spring wood in a pine is only 1/6 of that of summer wood. The compression strength of air-dry wood is about half of the corresponding tensile strength. The shearing strength of wood is 10-15 % of its tensile strength in the direction of the grain ... WebOak Wood – Thermal Conductivity. Thermal conductivity of Oak Wood is 0.17 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance’s ability to transfer heat through a material by conduction. sed no match
