Moment of inertia of a circular section can be calculated by using either radius or diameter of a circular section around centroidal x-axis or y-axis. Example Find the moment of inertia of a circular section whose radius is 8” and …

Moment of inertia is the product of first moment of area and the centroidal distance of the area from a given axis. If A.x is the first moment of area of certain section then (Ax).x is the moment of inertia (second …
