# Gear-tooth bending screening
# Scope: Pitch-circle tangential and radial forces; no tooth strength calculation.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

torque = 5 N*m
pitchDiameter = 50 mm
pressureAngle = 20 deg

tangential := 2*torque/pitchDiameter [N]
radial := tangential*tan(pressureAngle) [N]

check tangential force budget: tangential <= 300 N

scenario alternative: torque = 4 N*m


# Diagram dimensions are illustrative; teeth are schematic, not manufacturing profiles.
teeth = 25
module := pitchDiameter/teeth [mm]
check whole teeth: abs(teeth-round(teeth)) <= 0
check positive teeth: teeth >= 3
