A built-up beam made from fastening two channels to a wide flange section carries
loads` as shown. The fasteners are 12mm∅ bolts with allowable shear stress τ= 110 MPa. For
bearing, σb= 220MPa for single shear, and σb= 275 MPa for double shear. E=200 GPA. Fy=420
MPa. Do not round off between solution
