Hiya,
Can anyone tell me the relationship of the design values in the Wood Handbook to the stress ratings for calculating beam sizing? In particular, if we have an species for which the Modulus of Rupture is given, can the allowable fiber stress in bending be calculated from that?

Even the Modulus of Elasticity in the Wood Handbook, given in megapascals, doesn't convert to psi and make sense with the published E values in the NDS.

I'm missing something here, so if anyone can steer me to a reference if the answer is not easily posted here, thanks.
