Forced Damped Vibrations A machine weighing 900 kg rests on a spring support base of stiffness 60 kN/m along with a damper between the machine and the support with a damping coefficient of 5kN s/m. The support is subjected to an externally harmonic disturbing force represented by F=1500sin(30t). Determine the following steady state response of the damped mass-spring system: a. The amplitude of the machine mass. b. The phase angle. c. Identify the conditions needed for mechanical resonance and measures that are taken to prevent this from occurring.
