# Moment of Inertia Calculator

M * D2

## Formula

Moment of inertia = M * D2

Where,
M = Angular Mass of the Hollow material
D = Distance between axis and rotation

Moment of Inertia refers to a measure of an object's resistance to change its rotation. Moment of Inertia is also called as mass moment of inertia, rotational inertia, polar moment of inertia of mass, or the angular mass. The SI unit of moment of inertia is kgm2. The moment of inertia is measured as the inertia of a rotating body with respect to its rotation. Moment of Inertia is denoted by the symbol 'I'.

Moment of Inertia is a scalar (a number), with dimensions of distance squared times mass. Moment of Inertia is always relative to a given axis. This advanced online Moment of Inertia Calculator tool is used to calculate the moment of inertia of a rotating object.

Example:
Calculate the Moment of Inertia for the rotating object by the given details.
Enter the mass of hollow material: 5 (lbm,kg)
Distance between axis and rotation: 10 (ft,m)

Solution:
Apply Formula:
Moment of inertia = M * D2
Moment of inertia = 5*102
Moment of inertia = 5*100
Moment of inertia = 500
