,Q1
Which maintenance strategy runs equipment to failure and then repairs or replaces it?
A) Preventive maintenance
B) Predictive maintenance
C) Run-to-failure maintenance CORRECT
D) Proactive maintenance
Rationale
Run-to-failure (reactive) maintenance allows equipment to operate until it fails, then performs repair or
replacement.
Q2
What is the primary goal of preventive maintenance?
A) To detect the onset of failure through condition monitoring
B) To service equipment on a time- or usage-based schedule before failure CORRECT
occurs
C) To eliminate all maintenance activities
D) To correct failures after they happen
Rationale
Preventive maintenance is interval-based, servicing equipment according to calendar time or operating
hours regardless of current condition.
Q3
Predictive maintenance relies primarily on:
A) Calendar-based servicing intervals
B) Condition monitoring data to determine when maintenance is needed CORRECT
C) Fixing equipment after failure
D) Operator intuition alone
2
,Rationale
Predictive maintenance uses condition monitoring (oil analysis, vibration, thermography) to predict when
failure will occur and schedule maintenance accordingly.
Q4
Proactive maintenance focuses on:
A) Responding quickly after a failure occurs
B) Eliminating the root causes of failure before they cause damage CORRECT
C) Increasing maintenance frequency regardless of condition
D) Monitoring only vibration
Rationale
Proactive maintenance identifies and removes root causes of failure, such as contamination and
misalignment, to extend equipment life.
Q5
Reliability-Centered Maintenance (RCM) is best described as:
A) A strategy that applies the most appropriate maintenance approach for each
CORRECT
failure mode based on its consequences
B) A strategy that runs all equipment to failure
C) A strategy that replaces all components on a fixed schedule
D) A strategy that ignores failure consequences
Rationale
RCM systematically evaluates failure modes and their consequences to select the most effective
maintenance strategy for each.
Q6
What is the primary purpose of a lubricant in a machine?
A) To increase friction between surfaces
B) To reduce friction and wear, cool components, and transport contaminants CORRECT
3
, C) To serve as a structural component
D) To increase operating temperature
Rationale
Lubricants separate moving surfaces, reduce friction and wear, remove heat, and carry away debris.
Q7
Tribology is the study of:
A) Friction, wear, and lubrication CORRECT
B) Only lubrication
C) Only friction
D) Electrical systems
Rationale
Tribology encompasses the science of interacting surfaces in relative motion, including friction, wear, and
lubrication.
Q8
Which lubrication regime occurs when a full fluid film completely separates the surfaces?
A) Boundary lubrication
B) Mixed lubrication
C) Hydrodynamic lubrication CORRECT
D) Dry lubrication
Rationale
In hydrodynamic lubrication, a complete fluid film separates the surfaces, preventing asperity contact.
