A small rotating machine with mass m-75 kg is lying on an elastic foundation. The steady state excitation provided when the machine is operating is a simple harmonic force F = 1020 N. Design the foundation (i.e. calculate the pair k and c) such that the steady state displacement is 50% of the static deflection. Hint: In your calculation ignore the static deformation due to the weight of the system. Use the curve of the magnification factor provided below to identify the natural frequency of the system.
