Question 4 10 pts FOR THE MATERIAL The wood specie is Yakal w/ 63% stress grade. Bending loads will be about the strong axis of the cross-section. The members are braced so buckling is not a concern. The moisture content is < 19%. Normal temperature conditions apply. Assume no incising was incorporated for addition of preservatives and that a fire retardant factor = 1.0 is applied. Use 95% exceedence for MOE such that Ep.05 = E [ 1-1.645COVE] where COVE = 0.25 for VSG lumber and COVE = 0.11 for MSG lumber. Furthermore, the adjusted modulus of elasticity is given by E' = Ecos x (product of all applicable adjustment factors). Use appropriate Cp used based on the provided load combination (D+L). FOR THE SECTION Floor beams with nominal size of 6" X 16" support floor loads such that adjacent floor beams are spaced on-centers (O.C.-spacing) at 1.20m. Determine the Adjusted Compressive Design Value (Parallel to Grain), F for the member for the load combination, D+L. 04.940 MPa 4.792 MPa 12.000 MPa 11.640 MPa
