Area Moment of Inertia Section Properties of Square Tube at Center Calculator and Equations
This engineering calculator will determine the section modulus and Area Moment of Inertia Section Propertiesfor the given crosssection. This engineering data is often used in the design of structural beams or structural flexural members. There are two types of section moduli, the elastic section modulus (S) and the plastic section modulus (Z).
Description 
Equation 
Area Moment of Inertia Section Properties = I 

Section Modulus = Z = I/y 

Radius of Gyration 

A = area 

y = distance from axis to extreme fiber
