Direction of Greatest Wood Stiffness
Easywoodanisotropy
For clear wood, stiffness is generally greatest in which direction?
- ATangential to growth rings
- BLongitudinal, parallel to grain
- CRadial to growth rings
- DEqual in all directions

Answer: B. Longitudinal, parallel to grain
Wood is orthotropic. Its modulus parallel to the grain (longitudinal) is roughly 10–20 times the radial or tangential modulus. It is not isotropic.
