Wood beam Question.
A simply supported #1 DF-L (Douglas Fir-Larch) beam 8 foot in length has a point load of 2K at mid span. The beam is 4 x 8 in the strong axis orientation, and is fully braced, the moisture content is less than 19% and the max deflection is L/360. (include the weight of the beam in your calculations)

Find the Tabulated stresses.
Find the Allowable stresses
Find the Actual stresses
Is the member adequate.

Using the same parameters as above calculate assuming a moisture content above 19%.

Using the same parameters as problem #1, your supplier has advised you that DF-L is not available, the only wood available in a 4 x 8 is Western Cedars, is this acceptable alternative?
