Density (dry weight) = 31-37 lbs/cu. ft. 0 Density (dry weight) = 38-45 lbs/cu. ft. Shearing strength (parallel to grain) = low Modulus of Elasticity (stiffness) = very low Max. crushing strength = medium Bending strength (MOR) = low Shrinkage, Tangential = moderate Shrinkage, Radial = small Shrinkage, Radial = moderate Modulus of Elasticity (stiffness) = low Density (dry weight) = 23-30 lbs/cu. ft. Shrinkage, Tangential = small Shrinkage, Tangential = large Shrinkage, Tangential = fairly large Shrinkage, Radial = large Shrinkage, Radial = fairly large Shearing strength (parallel to grain) = very low
