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 ...

Two features of the section are used to determine the shape factor for bending, the overall area of the section, A, and the way the material is distributed about an axis of interest - the geometric ...

When I was talking about balancing a stick, I mentioned the moment of inertia. Moment of inertia is different than mass, but I like to call it the “rotational mass”. What does mass do?

Angular momentum (I will refer to its traditional name) also depends upon two things: the angular velocity and the moment of inertia. Typically, textbooks use the letter L to represent the angular ...
