For the section, lz, = 31.7(10-5) m4, lY’ = 114(10-5) m4, Iy,z' = -15.8(10-6) m4. Using the techniques outlined in Appendix A, the member’s cross-sectional area has principal moments of inertia of lz = 28.8(10-6) m4 and ly = 117(10-6) m4, calculated about the principal axes of inertia y and z, respectively. If the section is subjected to the moment M = 15 kN · m, determine the stress at point A using Eq. 6-17.
