For the section, I z' = 31.7(10 6 ) m 4 , I y ' = 114(10

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) m⁴and 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.
