Calculate the Moment of Inertial

You can calculate the moment of inertia by navigating to [Tools] tab → [Analysis].

From the [Analysis] dialog, under the [Moments of Inertia] tab, you can calculate the moment of inertia for assemblies or parts.

The moment of inertia is a measure of an object's resistance to rotational motion.

It follows the formula:

Torque = Moment of Inertia × Angular Acceleration

By calculating the moment of inertia, you can determine the torque required to achieve a certain angular acceleration.

For example, when manually rotating a large tire versus a small tire, it intuitively feels like more effort is required to rotate the larger one.

This increased effort indicates a larger moment of inertia.

Note that the moment of inertia is a separate concept from the second moment of area or section modulus used in bending calculations in strength of materials.

IRONCAD also allows you to calculate the moment of inertia about any arbitrary axis of rotation.
