Table 4 provides mechanical properties for many softwoods and hardwoods.
Mahogany, Africa at 12% Moisture content Modulus of Rupture, 10,700 psi
and Modulus of Elasticity 1,400,000 psi
Mahogany, Honduras at 12% Moisture content Modulus of Rupture, 11,500 psi
and Modulus of Elasticity 1,500,000 psi
Teak at 12% Moisture content Modulus of Rupture, 14,600 psi and Modulus
of Elasticity 1,550,000 psi
MOR & MOE is based on static bending of small, clear, straight grained
specimens. Values should be adjusted for Knots, Slope of grain,
Wet-conditions of use for exterior deck. Also use duration of load and
safety factor. See the NDS for appropriate factors.
