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?
