Elastic Section Modulus of a Square I Beam

 

Elastic Section Modulus of a Square I Beam formulas

\( S_{x} \;=\;  \dfrac{ I_{x} }{ C_{y}   } \) 

\( S_{y} \;= \; \dfrac{ I_{y} }{ C_{x}   } \) 

Symbol English Metric
\( S \) = elastic section modulus \( in^3 \) \( mm^3 \)
\( C \) = distance from centroid \( in \) \( mm \)
\( I \) = moment of inertia \( in^4 \) \( mm^4 \)
