Asection of pipe pertaining to a certain machine vibrates with large amplitude of compressor speed of 220 rp*. for arralyztng this system; spring mass system was suspended from the pipe to ict as an absoiber, a 1 kg absorber mass tuned to 220 cpm resulted in two resonant frequencies 188 and 258 cpm. what must be the mass and the spring stif& ress of the absorber if the resonant frequencies are to lie outside the range of 150 to 310 cpm?
