Density (dry weight) = 31-37 lbs/cu. ft. Modulus of Elasticity (stiffness) = low Hardness (side grain) = soft Density (dry weight) = 38-45 lbs/cu. ft. Bending strength (MOR) = medium Crushing strength = medium Shearing strength (parallel to grain) = very low Shearing strength (parallel to grain) = low Bending strength (MOR) = high
