A vibration isolation block will be installed in a laboratory so that the vibrations caused by the production in the adjacent factory do not affect the experiments inside. The mass of the insulation block is 1000 kg and the surrounding flooring and foundation vibrate at 1500 revolutions per minute. Calculate the required insulation stiffness for a movement amplitude less than 10% of the slab movement in the block. (Ignore damping.)
