Section II.1-1 Rectangular Moments and Product of Inertia

The second moments of an area, or rectangular moments of inertia, of an area with respect to the x and y axes - shown in the figure above - are defined as

The product of inertia of this general shape is defined as

In this course, the cross-sectional areas consist of simple geometric shapes, therefore, their moments of inertia can be calculated by a simple summation as opposed to the integral equations shown. More about this later!
