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!
