WebProblem: Determine the moment of inertia of a hollow sphere of mass 55 kg. The sphere has a radius of 0.120 m. Solution: The solution requires the following expression for calculation: I = (2/3)MR 2 Substituting the values in the above equation: I = (2/3) (55.0 kg) (0.120 m) 2 I = (55.0 kg) (0.0144 m 2) I = (2/3) (0.792 kg.m 2) WebA moment of inertia of a hollow sphere will be the same as any axis passing through its center.
