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 Numerical Data Item Green Dry English Bending Strength 10164 15844 psi Density 35 lbs/ft3 Hardness 995 lbs Maximum Crushing Strength 3916 6397 psi Shearing Strength 1221 psi Stiffness 1358 1568 1000 psi Weight 34 27 lbs/ft3 Item Green Dry Metric Bending Strength 714 1113 kg/cm2 Density 560 kg/m3 Hardness 451 kg Maximum Crushing Strength 275 449 kg/cm2 Shearing Strength 85 kg/cm2 Stiffness 95 110 1000 kg/cm2 References Brown, W.H.,1978,Timbers of the World, No. 2 South America,TRADA, Red Booklet Series Chaturvedi, M.D., Kobuski, C.E.,1969,Determinacion de las propriedades Mecanicas de algunas Maderas de,Impotancia Comercial en Chile,Instituto Forestal Chile Informe Tecnico,36 Chilean Forestry News,1979,Chilean Woods - Tineo (Weinmannia trichosperma Cav.,Chilean Forestry News 2(15) p14 France - Centre Technique du Bois,1971,Le Tineo (Weinmannia trichosperma,CTB Bulletin d'information techniques No.58 Guyana Forest Department,1967,Recopilacion de Propiedadas mecanicas de Maderas Creciendo en,Chile,Inst.
