Iin a flexural test of a standard 2 by 2 by 30-in. douglas-fir specimen (28-in. span), the deflection at midspan was 0.125 in. when the center load was 800 lbs., the load still being within the elastic range. the beam failed at a center load of 2,800 lbs. when the deflection was 0.600 in. compute the modulus of elasticity.
