Moment of Inertia of Circular Ring about Perpendicular Axis through its Center Calculator

Calculate Moment of Inertia





Formula

The formula to calculate Moment of Inertia (I) is:

\[ I = M \cdot r^2 \]

Where:

Definition

Moment of Inertia is the measure of the resistance of a body to angular acceleration about a given axis.

Mass of body is the quantity of matter in a body regardless of its volume or of any forces acting on it.

Radius of body is a radial line from the focus to any point of a curve.

How to calculate Moment of Inertia of Circular Ring about Perpendicular Axis through its Center

Let's assume the following values:

Using the formula:

\[ I = M \cdot r^2 \]

Evaluating:

\[ I = 12.6 \cdot 2.1^2 \]

The Moment of Inertia is 55.566 kg·m².
