When a washing machine, of mass \(200 \mathrm{~kg}\) and an unbalance \(0.02 \mathrm{~kg}\) - \(\mathrm{m}\), is mounted on an isolator, the isolator deflects by \(5 \mathrm{~mm}\) under the static load. Find (a) the amplitude of the washing machine and (b) the force transmitted to the foundation at the operating speed of \(1200 \mathrm{rpm}\).
