    The moment of inertia of a rotating solid disk about an axis through its center of mass is ½ MR2 . Suppose instead that axis the rotation passes through a point on the edge of the disk. Will the moment of inertia be the same, larger, or smaller?

    Moment of inertia be minimum about the centre of mass.

    When axis shifted to another one, parallel to axis passing through the CM, moment of inertia is increased ...

    Solution Summary

    A problem discussing about change in moment of inertia of a disk, as it's axis is shifted from the centre to the edge.
