Square Tube Center Calculator

The section properties like Inertia, Modulus, Area and Radius for a Square at center position cab be calculated though online Square Tube Section Properties Calculator.
Square Tube Center Calculator
A (Exterior Side) : mm
B (Interior Side) : mm
Inertia : mm4
Modulus : mm3
Radius : mm
Area : mm2
 
Formula
Inertia = (a4- b4) / 12
Modulus = (a4 - b4) / 6 * a
Radius = ((a2 + b2) / 12)1/2 Area = a2 - b2
Structural or mechanical tube is(at least, externally) dimensionally accurate and has a bright finish. It is also made from mild steel, and sometimes rolled and welded too.

Example:
Calculate the Square Tube Section properties for the given details.
A (Exterior Side) mm = 25
B (Interior Side)mm = 5

Solution:
Apply Formula:
Inertia = (a4- b4) / 12
Modulus = (a4 - b4) / 6 * a
Radius = ((a2 + b2) / 12)1/2 Area = a2 - b2

Inertia = 32500 (mm4)
Modulus = 78000 (mm3)
Radius = 2.124591463996994 (mm)
Area = 600 (mm2)
