Moment of Inertia calculators. Here is a list of the available calculation tools relative to the moment of inertia of a shape. More accurately, these tools calculate the second moment of area, which is a purely geometric property of a planar shape (not related to its mass). The second moment of area is commonly used in engineering disciplines ...

The moment of inertia list is given below with their formulas. 1. A System of Particles’ Moment of Inertia. I = Σ m i r i 2. This is the primary equation of the moment of inertia. 2. Rigid Bodies’ Moment of Inertia. I = ∫ r 2 d m. Here, dm = mass of the element.

I = mr². For a rigid body moving about a fixed axis, the laws of motion have the same form as those of rectilinear motion, with the moment of inertia replacing mass, angular replacing linear velocity, angular momentum replacing linear momentum, etc. Hence the kinetic energy of a body rotating about a fixed axis with angular velocity ω is ...
