Determine the allowable load (in pounds) on the shore based on end-bearing stresses between the shore
and the stringer, if you are using 4- by 4-inch stringers and 6- by 6- by 10-inch shores. The stringers can carry
350 pounds per square inch in compression perpendicular (CY) to their grain. Both members are made with
rough lumber.
