A vibration isolation block is to be installed in a laboratory so that the vibration form adjacent factory operations will not disturb certain experiments. If the weight of the isolation block is 800 lb and it vibrates vertically with an amplitude of 0.03 in at 20 Hz, determine the stiffness of the isolation system required to reduce the vertical-motion amplitude to 0.005 in. Neglect damping.
