Moment of inertia m.i. : definition
The second moment of area, or second area moment, or quadratic moment of area and also known as the area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis. The second moment of area is typically denoted with either an (for an axis that lies in the plane of the area) or with a (for an axis perpendicular to the plane). In both cases, it is calculated with a multiple integral over the object i… 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.
