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.)

All the components used in civil engineering and mechanical engineering applications undergo deformations due to induced internal stresses under the application of external loads. Under repeated application of loads, there is a high possibility of failure of the components. Hence, periodic monitoring of the components and determination of stresses are very important.
