1. The problem statement, all variables and given/known data Finding the maximum allowable force P before failure 2. Relevant equations Shear /normal stress = Force / Area 3. 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 factor of safety, from the failure stresses given and therefore, determine which P is lower which shall be the maximum allowable P. However, I do not see there the distance b come into play. Am i missing something?
