C-Channel Shape Elastic Section Modulus Calculator

This calculator calculates the section modulus for a channel section. This is done with the equation below.

S=BH26−bh36HS = \frac{BH^2}{6}-\frac{bh^3}{6H}

The following are the variables for the equations...

  1. 
    
    = the section modulus
  2. 
    
    = the breadth, i.e. the breadth of the channel section.
  1. 
    
    = the height, i.e. the height of the channel section.
  1. 
    
    = the total breadth, i.e. the breadth of the channel section.
  1. 
    
    = the total height, i.e. the height of the channel section.
