A printed circuit board of mass \(1 \mathrm{~kg}\) is supported to the base through an undamped isolator. During shipping, the base is subjected to a harmonic disturbance (motion) of amplitude \(2 \mathrm{~mm}\) and frequency \(2 \mathrm{~Hz}\). Design the isolator so that the displacement transmitted to the printed circuit board is to be no more than \(5 \%\) of the base motion.
