Torsional Stiffness FORMULA |
||
| \(\large{ k = \frac{ G \; J }{ l } }\) | ||
| Symbol | English | Metric |
| \(\large{ k }\) = torsional stiffness | \(\large{\frac{lbf-ft}{deg}}\) | \(\large{\frac{N-m}{rad}}\) |
| \(\large{ l }\) = length | \(\large{in}\) | \(\large{mm}\) |
| \(\large{ G }\) = shear modulus | \(\large{\frac{lbf}{in^2}}\) | \(\large{Pa}\) |
| \(\large{ J }\) = torsion constant (polar momentum of inertia) | \(\large{in^4}\) | \(\large{mm^4}\) |
