A built-up beam made from fastening two channels to a wide flange section carries loads as shown. The
fasteners are 12mmØ bolts with allowable shear stresst = 110 MPa. For bearing 0h= 220 MPa for
single shear, and op= 275 MPa for double shear. E= 200 GPa. F= 420 MPa
a. Determine the maximum bending stress on the section
b. Determine the maximum shearing stress at Neutral Axis.
