The formula to calculate the Helix Angle is:
\[ \psi = \tan^{-1}\left(\frac{L}{C}\right) \]
Helix Angle is the angle between any helix and an axial line on its right, circular cylinder, or cone.
Let's assume the following values:
Using the formula:
\[ \psi = \tan^{-1}\left(\frac{0.011}{11.5}\right) \approx 0.00095652144741256 \text{ radians} \]
