The calculation
M = Marm + Mcartridge + Mfixings fres = 1000 / (2π√(M × C)) M in grams; C in µm/mN
Assumptions & limits
An undamped single-axis approximation. Use mass and compliance for the same plane. Manufacturer effective-mass conventions vary; this is an estimate, not a compatibility guarantee.
