In this session, Jayaram.V will discuss Introduction to Area Moment of Inertia. It will be helpful for the aspirants preparing for GATE/ ISRO/ KPSC (Technical)/B.Tech Exams. This session will be conducted in Malayalam and the notes will be provided in English The moment of inertia thru the centroid is always the smallest you will calculate along that axis. The moment calculated about any other point must be larger. So the moment of inertia increases no matter which way you move from the centroid, and I = Io + A x^2. I >Io whether x is positive or negativ The moment of inertia must be specified with respect to a chosen axis of rotation. For a point mass, the moment of inertia is just the mass times the square of perpendicular distance to the rotation axis, I = mr 2. That point mass relationship becomes the basis for all other moments of inertia since any object can be built up from a collection of point masses. Common forms: Examples: General. Product of Inertia: The area product of inertia is defined as (4) The x and y terms inside the integral denote the centroidal position of the differential area measured from the y and x axes, respectively.
