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}S=6BH2​−6Hbh3​
The following are the variables for the equations...
﻿﻿S
 = the section modulus
﻿﻿b
 = the breadth, i.e. the breadth of the channel section.
﻿﻿h
 = the height, i.e. the height of the channel section.
﻿﻿B
 = the total breadth, i.e. the breadth of the channel section.
﻿﻿H
 = the total height, i.e. the height of the channel section.
