1. The problem statement, all variables and given/known data

a, Calculate centroid inclination of principal axis of section

b, Now calculate principal 2nd moment of area

c, Cargo nets produce a moment (my) about a section (Y axis only). If max bending at point A cannot exceed 380 N/mm^2, what is max my moment that can be applied to beam?

2. Relevant equations

3. The attempt at a solution

My attempt at this can be seen in the attached jpeg file.

I am not even 100% what I have done so far is on the right track, and how to make the next step. Any help would be really appreciated

thanks in advance
