Which of the following components is NOT part of a typical vibratory system?

• Rigidity

• Damping

• Temperature

• Mass

What is the purpose of using the Fast Fourier Transform (FFT) in vibration analysis?

• To convert vibration into sound

• To amplify the vibration signal

• To visualize vibration in the frequency domain

• To measure the temperature of the machine

How do you convert a frequency from RPM to Hertz?

• Multiply by 60

• Divide by 60

• Multiply by 100

• Divide by 100

What is the unit of measurement for cycles per second?

• CPM

• RPM

• Radians

• Hertz

What is the relationship between frequency and period?

• Period is the square of frequency

• Frequency is the square of period

• Period is the reciprocal of frequency

• Frequency and period are unrelated

Which unit is commonly used to measure the amplitude of vibrations?

• Meters per second squared (m/s²)

• Meters (m)

• Millimeters per second (mm/s)

• Hertz (Hz)

Why is the unit 'g' used in vibration analysis?

• It is a standard unit for frequency

• It represents the acceleration due to gravity

• It is used to measure velocity

• It measures the amplitude of vibrations

What does the envelope of acceleration help identify in vibration analysis?

• The overall energy of the vibration

• High-frequency defects like lubrication issues

• Defects in the machine's structure

• Low-frequency vibrations

In which spectrum would you look for defects related to the machine's rotation?

• Frequency spectrum

• Acceleration spectrum

• Velocity spectrum

• Displacement spectrum
