Question: A piece of machinery can be regarded as a rigid mass with two reciprocating rotating unbalanced masses such as that in Fig. The total mass of the system is 12 kg and each of the unbalanced masses is equal to 0.5 kg. During normal operation, the rotation of the masses varies from 0 to 600 rpm. Design a support system so that the maximum vibration amplitude will not exceed 10 percent of the rotating masses; eccentricity.
