Shearing strength (parallel to grain) = low Density (dry weight) = 46-52 lbs/cu. ft. Bending strength (MOR) = medium Shrinkage, Radial = fairly large Shearing strength (parallel to grain) = medium Max. crushing strength = high Density (dry weight) = 38-45 lbs/cu. ft. Density (dry weight) = 31-37 lbs/cu. ft. Shrinkage, Tangential = large Shrinkage, Radial = small Modulus of Elasticity (stiffness) = high Density (dry weight) = 53-60
