Question: Pr . 4 . A beam with the given cross - section is subjected to a resultant internal moment of M = 2 6 0

Pr.4. A beam with the given cross-section is subjected to a resultant internal moment of M=260kN-m directed as shown below.
a) Determine the bending stress at points A,B,D, and E on the given section.
b) Specify the orientation of the neutral axis.
Note: The location of the centroid C of the cross-sectional area must be determined first. Then find the moments of inertia about the principal axes.
