Understanding the 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 ...
In a state of bewilderment one fine day, I asked a group of three mechanical engineers at this company where I was then employed if they could please explain to me the concept of “moment of inertia ..
Users select a general beam shape, type in dimensions, and hit calculate. Results include moments and product of inertia ... Poisson's ratio, mass density, and so on. Hitting Calculate solves ...
But what about the moment of inertia? It might make more sense to also call this the rotational mass. It the property of the object that makes it more difficult to change the angular velocity.
But to really understand the moment of inertia you need to look at mass. You can think of mass as the amount of "stuff" in an object—but it also has to do with the change in motion (inertial mass).
