A wood box beam is constructed of two 260 [mm] x 50 [mm] boards and two 260 [mm] x 25 [mm] boards (sec figure). The boards are nailed at a longitudinal spacing. b=100 [mm].  If each nail has an allowable shear force F=1200 [N], and Vmax=10652.6 [N]. What is the magnitude of the shear stress at the midpoint of either top or bottom plank?
