Question
The cantilevered beam uses a W36ox79 wide-flange section. The geometric properties of
the section are given by the table. The beam is subjected to the concentrated load P and
to the couple moment Mo clockwise such that the bending moment just to the right of
point B is M = 11.7 kN.m. What is the bending stress at the uppermost point C of
the web at this cross section?
