A uniform circular disc of radicu R lies in the XY -plane with its centre at the orgin of co-oridinate system. Its moment of inertia about an axis, lying in the xy-plane, parallel to the x-axis and passing through a point on the y-axis at a distance y - 2R is I_(1) . Its moment of inertia about an axis lying in a plane perpendicular to xy-plane passing through a point on the x-axis at a distance x - d is I_(2) . If I_(1)= I_(2)the value of .d. is: |
