Torsion Constant for Rectangle Cross-section
Torsion Constant for Rectangle Cross-section formula
| \(\large{ J = a\;b^3 \left[ \frac{1}{3} - 0.21 \; \frac{b}{a} \; \left(1- \frac{b^4}{12\;a^4} \right) \right] }\) |
Where:
| Units | English | Metric |
| \(\large{ J }\) (Greek symbol alpha) = torsion constant | \(\large{\frac{lbf-ft}{rad}}\) | \(\large{\frac{N-m}{rad}}\) |
| \(\large{ a }\) = length of long edge of an rectangle | \(\large{in}\) | \(\large{m}\) |
| \(\large{ b }\) = length of short edge of an rectangle | \(\large{in}\) | \(\large{m}\) |
