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