Elastic Section Modulus of a Circle

 

Elastic Section Modulus of a Circle formula

\( S \;=\;   \dfrac{  \pi \cdot r^3 }{ 4 } \) 
Symbol English Metric
\( S \) = elastic section modulus \( in^3 \) \( mm^3 \)
\( \pi \) = Pi \(3.141 592 653 ...\) \(3.141 592 653 ...\)
\( r \) = radius \( in \) \( mm \)

Elastic section modulus of a circle is a geometric property used in structural engineering to calculate the maximum stress in a circular cross-section under bending.
