# Thermal expansion and restraint
# Scope: Free linear thermal expansion at constant coefficient.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

length = 1 m
coefficient = 0.000023 K^-1
rise = 50 K

expansion := length*coefficient*rise [mm]

check expansion budget: expansion <= 2 mm

scenario alternative: length = 0.8 m
