NEST2017PhysicsOscillations
A thin rod of mass 0.3 kg and length 0.2 m is suspended horizontally by a metal wire which passes through its centre of mass and is perpendicular to its length. The rod is set to torsional oscillation with a period of 2 s . The thin rod is replaced by an equilateral triangular lamina which is suspended horizontally from its centre of mass. If its period of oscillations is found to be 10 s , the moment of inertia of t
