While measuring the Strength of wood there are few qualities of wood that are checked. These qualities are its density, compressive resistance, and resistance against bending and hardness by pounds-force (IBF). Its density gives the idea of its weight in specific volume; its compressive resistance shows how much weight a plank of wood can bear before it ruptures up; its bending resistance shows either it has the power to stay in shape for long while. A dense wood with packed fibers is always best in strength.
Scale for measuring the hardness of Wood Janka hardness scale is used to measure the hardness of the wood. This indicates how many pounds of force (IBF) are needed to put a 0.444 inches steel ball into the surface of the wood. It exactly shows how much force any wood needs, more forces required will increase Janka rating which indicates more strength.
