WebArea Moment of Inertia. The second moment of area, more commonly known as the moment of inertia, I, of a cross section is an indication of a structural member's ability to resist bending. (Note 1) I x and I y are the moments of inertia about the x- and y- axes, respectively, and are calculated by: I x = ∫ y 2 dA. I y = ∫ x 2 dA.
