Assignment:
To determine the centroidal mass moment of inertia lc of a tire mounted on a hub, the wheel was suspended on a knife edge, as shown in Fig., and the natural period T was measured. Derive a formula for lc in terms of the mass m, the natural period 7' and the radius r from the center C to the support.
Provide complete and step by step solution for the question and show calculations and use formulas.
