Video for the introduction to the moment of inertia.
The video illustrates the concept of the moment of inertia. There are the moments of inertia, the second moment of area, and the mass moment of inertia; the difference between them lies in the fact that the second moment of Area is used for static regions and is used to determine various types of stress, such as bending moment and shear stress.
