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!
