A reciprocating compressor of mass 20 Kg runs at a constant speed

of 3000 rpm. After installation the forcing frequency is found to be too

closer to the natural frequency of the system. Design a dynamic

vibration absorber such that (a) the natural frequency of the main

system is equal to that of the absorber and (b) the ratio of the

operating frequency to the natural frequency is 0.75.
