Question

In the figure above, a beam meant to support a balcony is built up from Douglas Fir boards. The screw spacing is required for the design, as well as a maximum rating for the design load P. The screws to be used are standard 3? long #8 deck screws rated at 150 lbs working load in shear. Also, the allowable bending stress must not be exceeded. The design (resistance factor) factor is = .75 for wet wood, and a safety factor of 5 is required by code. Calculate the max load P and minimum fastener spacing S that meets the requirements given
