Consider two masses, one at A & other at D be placed arbitrarily.

Let

$I_3 =\text{Distance of mass placed at D from a,} \\\\ I_1 =\text{New mass movement of Inertia of the two masses,} \\\\ k_1 =\text{New radius of gyration,} \\\\ α=\text{Angular acceleration the body;} \\\\ I=\text{Mass moment of inertia …
