In order to evaluate mass moment of inertia of a connecting rod, the following observations were made during experimentation:
Mass of the connecting rod = 50kg
Distance between big end bearing and small end bearing centtres = 1000mm
Diameter of big end bearing = 100mm
Diameter of small end bearing = 50mm
Time period of oscillation while connecting rod was suspended from big end = 1.75 second
Time period of oscillation while connecting rod was suspended from small rod = 2.0 second.
Evaluate radius of gyration of the connecting rod about an axis through the centre of mass perpendicular to the plane of oscillation as well as mass moment of inertia of the rod about the same axis.
