Question 1
For a pure single-frequency sinusoidal vibration waveform, what is the exact mathematical relationship between the Root Mean Square (RMS) amplitude and the Zero-to-Peak (Peak) amplitude?
Correct Answer:
RMS = Peak / 1.414 (or 0.707 x Peak)
Question 2
A rotating shaft operates at a constant speed of 3000 RPM. What is the fundamental rotational frequency in Hertz (Hz)?
Correct Answer:
50 Hz
Question 3
In a simple harmonic motion system, what is the phase relationship of acceleration relative to displacement?
Correct Answer:
Acceleration leads displacement by 180 degrees
Question 4
A machine running at 3000 RPM exhibits a pure 1X sinusoidal displacement amplitude of 100 µm peak-to-peak. What is the equivalent 1X peak velocity amplitude?
Correct Answer:
15.71 mm/s peak
Question 5
According to the natural frequency equation for a single degree of freedom (SDOF) spring-mass system (fn = (1 / 2pi) * sqrt(k / m)), what happens to the natural frequency if the system mass (m) is quadrupled while stiffness (k) remains constant?
Correct Answer:
The natural frequency is reduced by 50% (halved)
