Section modulus of RHS
public
Section modulus of square hollow section (RHS)
Input
External height
$ H = 100 \; \; mm $
Internal height
$ h = 90 \; \; mm $
External width
$ B = 100 \; \; mm $
Internal width
$ b = 90 \; \; mm $
Result
Section modulus
$$ W_{y_{RHS}} = {{\left({ B \cdot H ^ 3 - b \cdot h ^ 3 }\right) \over \left({ 6 \cdot H }\right)}} \; \; , {mm ^ 3} $$
