In Reply to: Mark I think your equation is correct and a personal reflection. posted by tubesforever on November 17, 2005 at 14:35:46:
Mark do you think that the change in the moment of inertia or the effective mass is more in play for the extra detail I am hearing in the cartridge?Unless you changed the arm length the effective mass and the moment of inertia must have equal effect because they are the same thing.
What effect does silicone dampening make on the moment of inertia or effective mass of the arm
Silicone damping has no effect on the actual moment of inertia. It does however slow down the response of the tonearm to an applied force. To simulate the effect mathematically it is necessary to add a velocity dependent negative term to the simple harmonic motion equations describing the cartridge / arm combination. The addition of this term increases the period of each oscillation which is superficially similar to added effective mass, but it also reduces the amplitude of each successive oscillation, which is not.
