## Helix Angle WhenPitch Circle Diameter is Given Solution

STEP 0: Pre-Calculation Summary
Formula Used
helix_angle = acos(Number of teeth*Normal Module/Pitch Circle Diameter)
α = acos(z*mn/D)
This formula uses 2 Functions, 3 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
acos - Inverse trigonometric cosine function, acos(Number)
Variables Used
Number of teeth- The Number of teeth Value: Number of teeth
Normal Module - Normal Module is deifined as the unit of size that indicates how big or small a gear is. It is the ratio of the reference diameter of the gear divided by the number of teeth. (Measured in Millimeter)
Pitch Circle Diameter - Pitch Circle Diameter is the diameter of the pitch circle. (Measured in Millimeter)
STEP 1: Convert Input(s) to Base Unit
Number of teeth: 23 --> No Conversion Required
Normal Module: 0.001 Millimeter --> 1E-06 Meter (Check conversion here)
Pitch Circle Diameter: 0.001 Millimeter --> 1E-06 Meter (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
α = acos(z*mn/D) --> acos(23*1E-06/1E-06)
Evaluating ... ...
α = NaN
STEP 3: Convert Result to Output's Unit
NaN Radian -->NaN Degree (Check conversion here)
NaN Degree <-- Helix Angle
