The joint between a diagonal and a chord in a timber truss is shown. The compressive force P in the diagonal s 20 kN. Determine the compressive stress in the diagonal, the bearing stress on plane ab, and the shear stress on plane ac. Both the chord and the diagonal are 150 mm by 150 mm (full nominal size) in cross section.
