Moment of Inertia Formula The moment of inertia formula is a fundamental concept in engineering and physics that describes the distribution of mass in an object and its resistance to rotational motion. It plays a crucial role in understanding the behavior of rotating bodies and is used in various areas, including mechanics, dynamics, and rigid body physics.
However, this formula is the most simple method for calculating or determining the moment of inertia of objects or shapes. There are a lot of other elaborate objects and we have to apply different formulas to get the desired result. We further use the calculus method of integration as well. Formulas For Calculating Moment Of Inertia Here are some of the popular objects or various shapes for ...
The moment of inertia can also be expressed using another formula when the axis of the rod goes through the end of the rod. In this case, we use;

The moment of inertia of the hollow sphere is 0.528 kg.m 2. Hollow Sphere Formula Derivation We will now understand the derivation of the moment of inertia formula for a hollow sphere. First, let us consider or recall the moment of inertia of a circle which is I = mr 2 If we apply differential analysis we get; dl = r 2 dm We have to find the dm,
