    What Factors Determine the Maximum Allowable Force on a Wooden Beam?

    Homework Statement Finding the maximum allowable force P before failure Homework Equations Shear /normal stress = Force / Area The Attempt at a Solution I know that I can resolve the force P to be along and normal to the end of the wooden beam to find the respective forces separately,applying...
