torsion constant rectangle 1Torsion 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:

\(\large{ J }\)  (Greek symbol alpha) = torsion constant

\(\large{ a }\) = length of long edge of an rectangle

\(\large{ b }\) = length of short edge of an rectangle
