I suspect that the greater the inertia and effective mass of the arm, the greater the skating force is on the deflection of the cantilever. I also imagine that the performance over warps should also be affected by the location of the counterweight.
In general, however, the value of effective mass depends on the purpose for which it is used, and can vary depending on a number of factors. For electrons or electron holes in a solid, the effective mass is usually stated as a factor multiplying the rest mass of an electron, me (9.11 × 10 −31 kg).
