### METHOD FOR EVALUATING SHEAR PROPERTIES OF WOOD

shear properties of wood where the shear streas is in radial or tangential planes. If the shear force is across the grain, it is often termed "rolling" because of the tendency for the shearing forces to roll the wood fibers. The specimen is not difficult to fabricate, and the test gives a state of almost pure shear.
