# Section Modulus of Rectangular Tube Calculator

A section modulus is the property for a cross section used in the designing of beams. A tube in the shape of a rectangle is called as the rectangular tube. In this calculator, the section modulus of the rectangular tube is calculated. Enter the breadth and height of the inner and outer rectangle to find the section modulus.

A section modulus is the property for a cross section used in the designing of beams. A tube in the shape of a rectangle is called as the rectangular tube. In this calculator, the section modulus of the rectangular tube is calculated. Enter the breadth and height of the inner and outer rectangle to find the section modulus.

#### Formula:

S = ( B * H2 / 6 ) - ( ( b * h3 ) / ( 6 * H ) ) Where, B = Breadth of the Outer Rectangle H = Height of the Outer Rectangle b = Breadth of the Inner Rectangle h = Height of the Inner Rectangle

#### Example

If the breadth, height of inner and outer rectangle are 4,3,2,1 mm
S = ( ( 4 * 32 ) / 6 ) - ( ( 2 * 13 ) / ( 6 * 3 ) )
=5.889mm
