The beam in the figure below is fabricated by attaching a C180x14.6 channel to a W250x17.9 shape with 15-mm-dia rivets at uniform spacing “s". The maximum shear force in the beam is 65 kN. Given properties: C180x14.6: A = 1850 mm^2; d = 178 mm; xcg= 13.8 mm I, = 0.405x10^6 mm^4; tw = 5.3 mm; tf= 9.3 mm W250x17.9: A = 2270 mm^2; d= 251 mm; I = 22.4x10^6 mm^4 ty = 4.8 mm; tf= 5.3 mm C180 × 14.6 - W250 × 17.9
