An air compressor of mass 100 kg is mounted on an elastic foundation. It has been observed that, when a harmonic force of amplitude 100 N is applied to the compressor, the maximum steady-state displacement of 5 mm occurred at a frequency of 300 rpm. Determine the equivalent stiffness and damping constant of the foundation.
What is the compressor's steady state response when a 30kg absorber with a stiffness of 1.3*10^5 N/m is added to the end of the beam? Please determine how to change the absorber to minimize the response of the beam.
