1. The primary goal of a reliability program in an industrial facility is to:
A. Increase overtime hours
B. Reduce equipment availability
C. Maximize equipment performance while minimizing failures and
lifecycle costs
D. Eliminate preventive maintenance
Rationale: Reliability programs focus on improving asset availability,
reducing failures, and lowering total lifecycle costs through effective
maintenance and operational practices.
2. Reliability-centered maintenance (RCM) primarily determines:
A. Employee salaries
, B. Equipment purchase prices
C. The most effective maintenance strategy for each asset
D. Building construction methods
Rationale: RCM evaluates equipment functions, failure modes, and
consequences to identify the most appropriate maintenance strategy.
3. Which maintenance strategy is performed after equipment has failed?
A. Predictive maintenance
B. Preventive maintenance
C. Condition-based maintenance
D. Corrective maintenance
Rationale: Corrective maintenance restores equipment after failure has
occurred.
4. Predictive maintenance relies heavily on:
A. Random inspections
B. Equipment replacement schedules
C. Equipment condition monitoring
D. Employee attendance records
Rationale: Predictive maintenance uses condition-monitoring data to
detect developing faults before failure occurs.
, 5. Which instrument is commonly used for vibration analysis?
A. Hygrometer
B. Flow meter
C. Accelerometer
D. Thermocouple
Rationale: Accelerometers measure vibration levels that help identify
bearing, imbalance, and alignment problems.
6. Excessive vibration caused by unequal mass distribution is known as:
A. Misalignment
B. Resonance
C. Imbalance
D. Cavitation
Rationale: Imbalance occurs when rotating components have uneven mass
distribution around the axis of rotation.
7. Shaft misalignment most commonly causes:
A. Reduced electrical voltage
B. Lower oil viscosity
C. Excessive vibration and premature bearing failure
D. Increased fuel quality
Rationale: Misalignment places abnormal forces on bearings and
couplings, resulting in vibration and shortened equipment life.
, 8. Which bearing typically supports radial loads?
A. Thrust bearing only
B. Magnetic bearing
C. Ball bearing
D. Sleeve coupling
Rationale: Ball bearings are designed to support radial loads and moderate
axial loads.
9. Lubrication primarily reduces:
A. Voltage
B. Pressure
C. Friction and wear
D. Motor speed
Rationale: Lubricants minimize direct metal-to-metal contact, reducing
friction and extending component life.
10. Which lubricant property measures resistance to flow?
A. Density
B. Flash point
C. Viscosity
D. Acidity
Rationale: Viscosity indicates how easily a lubricant flows under specified
conditions.
