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