... compared to that obtained using the trifilar suspension. In the case of connecting rod, the above formula cannot be used since it does not have a regular shape; hence a second estimate is obtained by swinging the connecting rod as a compound pendulum. The connecting rod is suspended from a knife edge by means of the small-end bearing and the time is noted for its periodic time. This is then repeated with connecting rod suspended from the knife edge with the big-end bearing. The average of the two is then taken to get the moment of inertia. The moment of inertia with respect to the point of suspension is given by the following expression. I = T2 . M.g.l 4?2 Where; T = Periodic time M = Mass g = Acceleration due to gravity l = Distance from point of suspension to mass centre. The parallel axes theorem for both the small and ...
