# Thermal gap and assembly clearance
# Scope: Required free gap from uniform linear expansion plus tolerance.
# 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 = 60 K
tolerance = 0.2 mm
gap = 2 mm

required := length*coefficient*rise+tolerance [mm]

check gap sufficient: gap >= required

scenario alternative: length = 0.8 m
