Question:

A machine is excited at a frequency of $30 \mathrm{~Hz}$ by a force with an amplitude of $200 \mathrm{~N}$. It is desired to eliminate steady-state vibrations of the machine by addition of a vibration absorber.

(a) What frequency should the absorber be tuned?

(b) If the mass of the absorber is $3 \mathrm{~kg}$, what is the stiffness of the absorber?

(c) When the machine is excited at $30 \mathrm{~Hz}$, what is the amplitude of vibration of the absorber?

(d) What is the frequency of the absorber vibrations?
