MOR—modulus of rupture: strength measurement of the load required to break a test sample. MOE—modulus of elasticity: stiffness measurement. COMP—compression perpendicular to grain. Impact Bending—drop distance in in. for a 50-lb hammer to break sample. SP. GR.—specific gravity. ¹Burr oak figures from Wood Handbook (USDA Ag. Handbook #72).
