A 6.0 - m long rod has a mass of 1⁄3kg. Its moment of inertia from an axis at one of its end is (in kg. m2)
If body is assume to be continuous, then one can use the technique of integration to obtain the moment of inertia of the body about given axis or line. The elements should be choosen that the perpendicular from different points of element to given line differ only infinitesimal amounts... Please comment if you have any doubts..
