A 200 kg machine is attached to a şırınga of stifness 4×10^5 N/m . During operation the machine is subjected to a harmonic excitation of magnitude 500 N and frequency 50 rd/s. 1. Design an undamped vibration absorber such that the steady state amplitude of the primary mass is zero and the steady state amplitude of the absorber mass is less than 2 mm. 2. What are the natural frequencies of the system with the absorber in place ?
