MASS MOMENT OF INERTIA OF A HOLLOW SPHERE

"Mass Moment of Inertia of a Hollow Sphere Calculator" has been developed to calculate mass moment of inertia (rotational inertia) of a hollow spherical shell about its center of the mass.

Equations used for mass moment of inertia calculations for a hollow sphere are given in the "List of Equations" section.
