4. A machine with a rotating shaft has a total weight of 200lb and is supported by springs. The damping constant for the system is found to be 3lbsec/in. The resonant speed is determined experimentally to be 1200rpm, and the corresponding amplitude of the main mass of the machine is 0.50in. Determine the amplitude for a speed of 2400rpm. Also determine the fixed value the amplitude will eventually approach at high speed.
