# Bolt torque and preload estimate
# Scope: Torque-factor preload estimate with supplied nut factor.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

torque = 10 N*m
diameter = 6 mm
nutFactor = 0.2

preload := torque/(nutFactor*diameter) [N]

check preload budget: preload <= 10000 N

scenario alternative: torque = 8 N*m
