Explanations
Question 1: When checking machine vibration with a hand probe,
what is the FIRST precaution that must be taken?
A. Verify the data collector battery level
B. Ensure the machine guards are in position and secured
C. Calibrate the vibration sensor
D. Notify the production supervisor
CORRECT ANSWER: B. Ensure the machine guards are in position
and secured
Rationale: Safety is the paramount concern before any predictive
maintenance activity. Before approaching rotating equipment with a hand
probe, the technician must verify that all machine guards are properly
installed and secured to prevent entanglement or contact with moving
parts.
Question 2: Vibration analysis is primarily used in predictive
maintenance because vibration results in which of the following?
A. Increased energy efficiency
B. The majority of all rotary equipment failures
C. Reduced lubricant consumption
D. Improved bearing alignment
CORRECT ANSWER: B. The majority of all rotary equipment
failures
Rationale: Vibration is a leading indicator of mechanical degradation.
Studies and industry practice recognize that excessive vibration contributes
to the majority of failures in rotating machinery, making it a critical
parameter for condition monitoring.
,Question 3: A graphic representation of amplitude as a function of
time is known as what?
A. Spectrum
B. Waveform
C. Phase diagram
D. Bode plot
CORRECT ANSWER: B. Waveform
Rationale: A waveform displays amplitude on the vertical axis and time on
the horizontal axis. This time-domain representation is fundamental to
vibration analysis and is distinct from frequency-domain plots such as
spectra.
Question 4: Acceleration parameters are particularly useful at high
frequencies for detecting which condition?
A. Misalignment
B. Bearing failure
C. Soft foot
D. Looseness
CORRECT ANSWER: B. Bearing failure
Rationale: High-frequency vibration, measured as acceleration, is
characteristic of impacting events such as those occurring in deteriorating
rolling element bearings. Acceleration measurements are more sensitive to
these early-stage defects than velocity or displacement.
Question 5: Vibration velocity is typically measured in which unit?
A. Mils
B. Gs
C. In/sec
D. Microns
CORRECT ANSWER: C. In/sec
Rationale: Velocity is the rate of change of displacement with respect to
time. In customary industrial vibration measurement, velocity is expressed
,in inches per second (in/sec). Mils measure displacement, while Gs
measure acceleration.
Question 6: Routes for vibration data collection need to be exactly
defined for which primary reason?
A. To reduce travel time between machines
B. Because data are loaded to computers in a specific order
C. To ensure the same technician collects all data
D. To minimize sensor wear
CORRECT ANSWER: B. Because data are loaded to computers in a
specific order
Rationale: Consistent, repeatable measurement locations and sequences
are essential for trend analysis. Defined routes ensure that data is collected
in a predetermined order that matches the database structure, allowing
valid comparisons over time.
Question 7: Machines in good condition generally exhibit a fairly
stable vibration pattern referred to as what?
A. Baseline spectrum
B. Signature analysis
C. Trending curve
D. Alarm threshold
CORRECT ANSWER: B. Signature analysis
Rationale: The stable vibration pattern of a healthy machine is its signature.
Signature analysis involves comparing current vibration data against this
established reference to detect changes indicative of developing faults.
Question 8: Historical vibration data should include readings from
which three axes?
A. Vertical, radial, and tangential
B. Horizontal, vertical, and axial
, C. Radial, axial, and torsional
D. X, Y, and Z
CORRECT ANSWER: B. Horizontal, vertical, and axial
Rationale: To fully characterize a machine's vibration, measurements must
be taken in three orthogonal directions: horizontal, vertical, and axial. This
allows detection of faults that may manifest more strongly in one direction.
Question 9: Static unbalance exists under which condition?
A. The weight distribution axis intersects the axis of rotation
B. The weight distribution axis is parallel to and does not lie on the axis of
rotation
C. Two equal weights are placed 180 degrees apart in different planes
D. The rotor has no eccentricity
CORRECT ANSWER: B. The weight distribution axis is parallel to
and does not lie on the axis of rotation
Rationale: Static unbalance occurs when the principal axis of inertia is
displaced parallel to the shaft axis. This creates a centrifugal force that acts
in a single direction as the rotor turns.
Question 10: As the speed of rotation of a machine approaches the
object's natural frequency, what condition occurs?
A. Harmonic distortion
B. Resonance
C. Damping
D. Modulation
CORRECT ANSWER: B. Resonance
Rationale: Resonance is the phenomenon where the excitation frequency
matches the natural frequency of the system, resulting in greatly amplified
vibration amplitudes. This condition is potentially destructive and must be
avoided.
