Question: 2 a shaft having a stiffiness of 375 mnm rotates...

Question details

2. A shaft, having a stiffiness of 3.75 MN/m, rotates at 3de the shaft. tor, having a mass of 60 k Determine (a) the steadystate whirl amplitude of the rotor (b) th onditions. Assume the damping ratio of the system as 0.05. (c) Discuss how the stationary and rotary damping can be increased. g and an eccentricity of 2000 microns, is mounted on the shaft. e maximum whirl amplitude of the rotor during start-up and stopping Shaft Rotor or disc
