Max. crushing strength = medium Shearing strength (parallel to grain) = low Hardness (side grain) = soft Modulus of Elasticity (stiffness) = very low Modulus of Elasticity (stiffness) = low Bending strength (MOR) = medium Bending strength (MOR) = low Toughness-Hammer drop (Impact Strength) = medium Shrinkage, Tangential = moderate Density (dry weight) = 46-52 lbs/cu. ft. Shrinkage, Radial = very small Density (dry weight) = 38-45 lbs/cu. ft. Shrinkage, Volumetric = small Shrinkage, Tangential = small Shrinkage, Radial = small Shrinkage, Radial = moderate Shearing strength (parallel to grain) = medium
