# Wire-bundle fit through a bore
# Scope: Area-based circular bundle envelope at supplied packing fraction; no exact circle packing.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

count = 10
wireDiameter = 2 mm
packing = 0.7

area := count*pi*wireDiameter^2/(4*packing) [mm^2]
bundleDiameter := sqrt(4*area/pi) [mm]

check bundle diameter budget: bundleDiameter <= 10 mm

scenario alternative: count = 8
