A load P = 50 kN is applied to a rolled steel angle (Ix = Iy = 570 × 103 mm4, Ixy = −332.5 × 103 mm4, and A = 1148 mm4) by means of a 76 mm by 6 mm plate riveted to the angle (Figure P7.32). The action line of load P coincides with the ccntroidal axis of the plate. Determine the maximum stress at a section, such as AA, of the angle. Hint: Resolve the load P into a load (equal to P) at the centroid of the angle and a bending couple.
