Elastic Section Modulus of a Circle Segment formula |
||
| \( S \;=\; \dfrac{ I_x }{ C_y - r \cdot cos \left( \dfrac{ \Delta }{ 2 } \right) } \) | ||
| Symbol | English | Metric |
| \( S \) = elastic section modulus | \( in^3 \) | \( mm^3 \) |
| \( C_x, C_y \) = distance from centroid | \( in \) | \( mm \) |
| \( \Delta \) = angle | \( deg \) | \( rad \) |
| \( I \) = moment of inertia | \(lbm\;/\;ft^2-sec\) | \(kg\;/\;m^2\) |
| \( r \) = radius | \( in \) | \( mm \) |
