Two wood box beams (beams A and B) have the same outside dimensions (200mm x 360mm) and the same thickness (t=20 mm) throughout, as shown in the Figure (3). Both beams are formed by nailing, with each nail having an allowable shear load of (250 N). The beams are designed for a shear force (V = 4.0 kN). (A) What is the maximum longitudinal spacing (SA) for the nails in beam (A)? (B) What is the maximum longitudinal spacing (SB) for the nails in beam (B)? (C) What is the largest shearing stress
