Determine the bending stress at point A of the beam, and the orientation of the neutral axis.

Question:

Determine the bending stress at point A of the beam, and the orientation of the neutral axis. Using the method in Appendix A, the principal moments of inertia of the cross section are I_z' = 8.828 in⁴and I_y' = 2.295 in⁴, where z' and y' are the principal axes. Solve the problem using Eq. 6€“17.
