Q.1 (d) An instrument package having mass of 125 kg is to be mounted in a train
on console that experiences a vibration amplitude of 10 mm at a frequency
of 35 Hz while the train is running. Determine (a) the spring constant
necessary for a mount in order to achieve 80% isolation and (b) the
resulting vibration amplitude of the instrument package. Neglect the
damping in the system.
