Welcome to our calculator for moment of inertia for a solid rectangular section. Enter the height (H) and width (B) of your section below, and see the results in the output section below.

This tool calculates Ixx and Iyy about the centroidal axis.


Calculation

Inputs



H
:100mm​



B
:120mm​


Outputs

Moment of inertia


Ixx
:10000000mm4​



Iyy

Explanation

The moment of inertia of a solid rectangular section can be calculated using the equations show to the right. B represents the section's width, and H is its height.

Ixx=BH312 Iyy=B3H12I_{xx} = \frac{BH^3}{12} \\\ \\ I_{yy} = \frac{B^3H}{12}
