고체역학 (Gere) — Stresses in Beams (Advanced Topics): Problem 6.10-10

6.10-10 Solve the preceding problem for an IPN 400 beam. Assume that \(\sigma_Y = 250 \text{ MPa}\). Obtain the cross-sectional dimensions and section modulus of the beam from Table F-2 in Appendix F. [Note: The preceding problem 6.10-9 requires determining the yield moment \(M_Y\), plastic moment \(M_p\), and shape factor \(f\).]
