A uniform rod of length l is suspended from any point P. It is then made to undergo small oscillations. If P is the

T=2πImgl. Here, l s distance of point P from centre of mass.When P is the centre, l = 0. Therefore, T = ∞, i.e. rod will not oscillate.When P is end point, I=ml23∴                               T=2πml23mgl=2πl3g
