Solve Prob. 6€“111 using the equation developed in Prob. 6€“106.

Data from 6-106

For the section, I_z' = 31.7(10^ˆ’6) m⁴, I_y' = 114(10^ˆ’6) m⁴, I_y'z' = ˆ’15.8(10^ˆ’6) m⁴. Using the techniques outlined in Appendix A, the member€™s cross-sectional area has principal moments of inertia of I_z = 28.8(10^ˆ’6) m⁴ and I_y = 117(10^ˆ’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.
