Moment of Inertia Calculator: Solid Rectangular Section

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
:90mm



B
:50mm


Outputs

Moment of inertia


Ixx
:3.04e+6mm4



Iyy
:9.38e+5mm4


Dimensions


Area
:4500mm2



xc
:25mm



yc
:45mm


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}
