Answer →

Let us consider a uniform rod of mass (M) and length (l) as shown in figure. Let us find an expression for moment of inertia of this rod about an axis that passes through the center of mass and perpendicular to the rod. ... The moment of inertia (dI) of this mass (dm) about the axis is, dI = (dm) x^2.
