I should probably know the answer to this but anyway....(adsbygoogle = window.adsbygoogle || []).push({});

I want to compute the critical buckling load for a simple 3D rectangular cross-section beam, though the thickness in the z-direction is small.

If a load is applied in the negative y direction, which direction do I use for my second moment of area value? Ixx or Iyy?

Thanks for any info.
