... measuring the time taken for 20 oscillations. By using the equation 1 the moment of inertia of the bar about the axis through its center of mass can be calculated. The same procedure is followed for the connecting rod and its moment of inertia about the axis passing through its center of mass was found. After that the connecting rod was suspended by a one end from a knife-edge, and given a small angular displacement. The time taken for 20 oscillations was measured and the periodic time was found. By using equation 2 the moment of inertia of the rod about the axis through the point of suspension can be found. The same procedure was followed, by suspending the rod by the other end. Using equation 2, moment of inertia of the rod about the axis through the point of suspension can be found. Finally by using the parallel axis theorem ...
