Where is the point of maximum compressive stress in bi-axial bending?

[DrVirz]

Hi all,

I've attempted this question however my solution seems too simple..? I have taken the point 'A' (bottom right corner of beam) as the point with max compressive stress, I am not sure if this is correct. I have just assumed this by observation.

Everything looks OK. You caught the typo in the units for the moments of inertia; very good.

Well that's great news! For some reason I thought my solution seemed to simple!

Thanks for clearing that up!
