Question 1

What is moment of inertia?

Accepted Answer

Moment of inertia measures how difficult it is to rotate an object around an axis. It depends on mass distribution relative to the rotation axis.

Question 2

How do I calculate moment of inertia for different shapes?

Accepted Answer

Each shape has a specific formula. This calculator provides moment of inertia for common shapes like cylinders, spheres, rods, and plates.

Question 3

What units are used for moment of inertia?

Accepted Answer

SI unit is kg·m² (kilogram-meter squared). Other units include g·cm², lb·ft², and slug·ft². This converter handles all common unit conversions.

Question 4

Why is moment of inertia important?

Accepted Answer

It determines rotational dynamics, angular acceleration, and stored rotational energy. Essential in mechanical engineering, physics, and vehicle dynamics.
