Transcribed Image Text: An electric motor is mounted on a steel table. The deflection of the table under the weight of the
motor is observed to be 4 mm. the mass of the motor added to the effective mass of the table is 50
kg. The rotating parts of the motor have a mass of 10 kg and have an eccentricity of 12 mm.
During free vibration, it is observed that the displacement of 40 mm is reduced to 2 mm in 1
second. Find the amplitude of motion if the operating speed of the motor is 1750 rpm. Assume the
damping is viscous.
