PROBLEM 4.3 Using an allowable stress of 155 MPa, determine the largest bending moment M that can be applied to the wide-flange beam shown. Neglect the effect of fillets. PROBLEM 4.4 Solve Prob. 4.3, assuming that the wide-flange beam is bent about the y axis by a couple of moment My. PROBLEM 4.3. Using an allowable stress of 155 MPa, determine the largest bending moment M that can be applied to the wide-flange beam shown. Neglect the effect of fillets.
