# Compression-spring solid-height clearance
# Scope: Helical compression spring approximate solid length using total coils.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

wire = 2 mm
totalCoils = 10
freeLength = 50 mm
travel = 20 mm

solid := wire*totalCoils [mm]
reserve := freeLength-travel-solid [mm]

check coil clearance: reserve >= 3 mm

scenario alternative: wire = 1.6 mm
