Solution:

A delicate instrument which weighs 450 N is to be spring mounted to the floor of a test slab which occasionally vibrates with a frequency of 10Hz and maximum amplitude of 2.5mm. Determine the stiffness of the isolation spring required to reduce the vertical amplitude of the instrument to 0.025mm if the instrument is isolated with dampness with a damping ratio of 2%
