Max. crushing strength = medium 0 Bending strength (MOR) = medium Modulus of Elasticity (stiffness) = low Shrinkage, Tangential = large Shrinkage, Radial = fairly large Hardness (side grain) = soft Bending strength (MOR) = low Bending strength (MOR) = high Work Maximum Load = Low Shrinkage, Volumetric = moderate Shrinkage, Radial = large Shearing strength (parallel to grain) = medium Modulus of Elasticity (stiffness) = very low Max. crushing strength = high Density (dry weight) = 46-52 lbs/cu. ft. Density (dry weight) = 38-45 lbs/cu. ft. Toughness-Hammer drop (Impact Strength) = low Toughness (total work) = medium Shrinkage, Volumetric = small Shrinkage, Volumetic = fairly large Shrinkage, Tangential = moderate Shrinkage, Tangential = fairly large Resists denting and marring Heavy Hardness = medium Hardness (side grain) = very soft Dnesity (dry wieght) = 53-60 lbs/cu. ft.
