The 2nd moment of area, also known as moment of inertia of plane area, area moment of inertia, or second area moment, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis.

The moment of inertia, I, is a measure of the way the mass is distributed on the object and determines its resistance to angular acceleration. Every rigid object has a de nite moment of inertia about a particular axis of rotation. The moment of inertia of a collection of masses is given by: I= mir i 2 ()

The moment of inertia calculates the rotational inertia of an object rotating around a given axis. It represents how difficult it overcomed to change its angular motion about that axis. Moment of inertia of a same object will change against different axis. The more far away from the axis, the more moment of inertia the object has.
