If i have a simply supported J Section beam, when i'm calculating the max deflection, what value of I do i use???(adsbygoogle = window.adsbygoogle || []).push({});

I have already had to calculate Ix, Iy and Ixy.

I would imagine that as deflection occurs along the y axis that i would use Iy.

Or do i use Imin? I have already calculated this too.

Any help would be gratefully appreciated as i'm completely stuck!!!
