8. Area moment of Inertia
The area moment of inertia (also called the second
moment of area) defines the resistance of a cross-section
to bending, due to the shape of the cross-section. It is a
key parameter for the analysis of beams and columns.

9. The area moment of inertia reflects how the area of the cross-
section is distributed relative to a particular axis.
