structural dynamics, Civil Engineering

Assignment Help:
A machine of 850 kg mass is acted upon by an external force of 1355 N at a frequency of 650 rpm. To reduce the effects of vibrations on the supporting structure, isolators having static deflection of 3 mm under the machine load are used. The damping factor of 0.44 is considered. Determine i) the force transmitted to the supporting structure ii) amplitude of vibration iii) phase angle.
