* How the maximum whirl amplitude can be reduced?
* III .Identify the Possible Causes and Effects of Vibrations in Rotating Machinery.

QUESTION NO 2: Steam turbines are efficient but complex machines, meaning that there are a number of possible ways they may malfunction. One such malfunction is known as vibration, which imposes additional load on bearings and coupling components. A turbine shaft, has a stiffness of 3.75 MN/m, and the rotation speed is 3600 rpm. The turbine rotor, has a mass of 60,000 grams and an eccentricity of 2000 microns, is mounted on the shaft. The system is underdamped with a damping ratio of 0.05. I. Determine the steady state whirl amplitude of the rotor. II. When will the whirl amplitude of the rotor be maximum? Calculate the maximum whirl amplitude of the rotor. How the maximum whirl amplitude can be reduced? III. Identify the Possible Causes and Effects of Vibrations in Rotating Machinery. Figure 2: Turbine Shaft and Rotor
