# Rotor unbalance force
# Scope: Single-plane unbalance force at operating speed.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

eccentricMass = 1 g
radius = 20 mm
speed = 3000 rpm

unbalance := eccentricMass*radius [g*mm]
force := eccentricMass*radius*speed^2 [N]

check unbalance force budget: force <= 3 N

scenario alternative: eccentricMass = 0.8 g
