In the theoretical determination of the moment of inertia with the additional masses, it was assumed that the masses are points. The radius of the added cylindrical masses is 2.85 cm and the mass of a single added mass is 1350 g. Convert to SI units. Using the parallel-axis theorem, calculate the moment of inertia taking into account the diameter (radius) of the masses. Determine the percentage difference between this and the previous value. Is it a good approximation to assume that the masses are points in this particular case?
