Strength Properties of Wood for Practical Applications

Compression of wood and wood-based materials plays an important role in almost any construction projects. If the compression strength or bending strength of a 2-inch by 4-inch beam is not known, deflection due to bearing a load may cause significant deformation, which could even lead to its failure during service life.
