고체역학 (Beer) — Pure Bending: Problem 4.4

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. 4.4 Solve Prob. 4.3, assuming that the wide-flange beam is bent about the \(y\) axis by a couple of moment \(M_y\).
