Introduction

Welcome to our calculator for moment of inertia, also known as a rotational inertial calculator for a solid circular section. Enter the diameter (D) of your section below, and see the results in the output section below.
This tool calculates Ixx and Iyy about the centroidal axis.

Explanation

The moment of inertia of a solid circular section can be calculated using the equations shown to the right. D represents the section's diameter

Enter your inputs, and see outputs for Ixx and Iyy and section dimensions below!
