A (50 mathrm{~kg}) machine is mounted on an isolator with a stiffness of (6 times 10^{5} mathrm{~N}

Question:

A $50 \mathrm{~kg}$ machine is mounted on an isolator with a stiffness of $6 \times 10^{5} \mathrm{~N} / \mathrm{m}$. During operation, the machine is subject to a harmonic excitation with a frequency of $140 \mathrm{rad} / \mathrm{s}$.

(a) What is the frequency ratio?

(b) Does this isolator actually isolate the vibrations?
