## Helix Angle in terms of Pressure Angle Solution

STEP 0: Pre-Calculation Summary
Formula Used
helix_angle = acos(tan(Normal Pressure Angle)/tan(Transverse Pressure Angle))
α = acos(tan(αn)/tan(α))
This formula uses 3 Functions, 2 Variables
Functions Used
cos - Trigonometric cosine function, cos(Angle)
tan - Trigonometric tangent function, tan(Angle)
acos - Inverse trigonometric cosine function, acos(Number)
Variables Used
Normal Pressure Angle - Normal Pressure Angle is defined as the angle between the tooth face and the gear wheel tangent. (Measured in Degree)
Transverse Pressure Angle - Transverse Pressure Angle is defined as the angle of the projection of the load into the plane to the shaft axis. (Measured in Degree)
STEP 1: Convert Input(s) to Base Unit
Normal Pressure Angle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
Transverse Pressure Angle: 30 Degree --> 0.5235987755982 Radian (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
α = acos(tan(αn)/tan(α)) --> acos(tan(0.5235987755982)/tan(0.5235987755982))
Evaluating ... ...
α = 0
STEP 3: Convert Result to Output's Unit
0 Radian -->0 Degree (Check conversion here)
FINAL ANSWER
0 Degree <-- Helix Angle
