The formula to calculate the torque (M) provided by a spiral spring is:
\[ \text{M} = \frac{\pi \cdot E \cdot b \cdot t^3 \cdot \theta}{6 \cdot L} \]
Where:
Spiral torsion is the measure of torque of the moment about an axis caused by a helical spring and twisting force.
Let's assume the following values:
Using the formula to calculate the Torque:
\[ \text{M} = \frac{\pi \cdot 200 \cdot 10 \cdot 1^3 \cdot 0.5}{6 \cdot 100} = \frac{3141.59}{600} \approx 5.24 \text{ Nm} \]
The Torque is approximately 5.24 Nm.
