Using the techniques outlined in Appendix A, Example A.5 or A.6, the Z section has principal moments of inertia of Iy = 0.060(10-3) m4 and Iz = 0.471 (10-3) m4. computed about the principal axes of inertia y and z respectively. If the section is subjected to an internal moment of M - 250 N • m directed horizontally as shown, determine the stress produced at point B. Solve the pioblem using Eq. 6-17.
