![]() ![]() ![]() From perpendicular axis theorm the MI through center. The unit of dimension of the second moment of area is length to fourth power, L 4, and should not be confused with the mass moment of inertia. This holds true for all regular polygons. So,MI about any axis through its centre parallel to both perpendicular sides will be (ma/12). The second moment of area, also known as area moment of inertia, is a geometrical property of an area which reflects how its points are distributed with respect to an arbitrary axis. ![]() ![]() The result is valid for both a horizontal and a vertical axis through the centroid, and therefore is also valid for an axis with arbitrary direction that passes through the origin. ![]()
