# Gear module and diametral pitch
# Scope: Metric spur pitch module from diameter and tooth count.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

diameter = 60 mm
teeth = 30

module := diameter/teeth [mm]
circularPitch := pi*module [mm]

check module target: module <= 3 mm

scenario alternative: diameter = 48 mm
