It has strong cellulosic fibers running along the grain and weaker lignin holding the fibers together in the transverse direction. This is why it splits more readily along the grain. Low Young's modulus does not make a material weak, but rather flexible. Elasticity is derived from atomic scale bond strength while bulk strength is derived from microstructural features. Otherwise good answer! | |
