1. Which of the following best describes the primary goal of
reliability engineering?
a) Minimize production costs
b) Maximize equipment uptime
c) Increase product variety
d) Reduce employee turnover
b) Maximize equipment uptime
Reliability engineering focuses on ensuring equipment operates
without failure to maximize uptime and productivity.
2. Mean Time Between Failures (MTBF) is used to measure:
a) Maintenance cost per unit
b) Average operating time before failure
c) Production throughput
d) Labor efficiency
b) Average operating time before failure
MTBF quantifies the average time a system functions before
experiencing a failure, helping predict reliability.
3. Which type of maintenance is performed based on actual
equipment condition rather than a fixed schedule?
a) Preventive
b) Predictive
c) Corrective
d) Reactive
, b) Predictive
Predictive maintenance uses condition monitoring to determine
when maintenance is needed, preventing unnecessary work and
failures.
4. A vibration analysis program is primarily used to detect:
a) Electrical faults
b) Misalignment and bearing defects
c) Hydraulic leaks
d) Operator errors
b) Misalignment and bearing defects
Vibration analysis identifies mechanical issues such as imbalance,
misalignment, or bearing wear before they cause failures.
5. Which of the following is a leading indicator of equipment
reliability?
a) Number of breakdowns
b) Number of safety incidents
c) Maintenance backlog
d) Equipment inspection findings
d) Equipment inspection findings
Leading indicators help predict failures before they occur, such as
trends observed in inspections and condition monitoring.
6. Which maintenance strategy is most suitable for critical
equipment with high failure consequences?
a) Run-to-failure
b) Preventive maintenance
c) Predictive maintenance
d) Corrective maintenance
c) Predictive maintenance
, Critical equipment benefits most from predictive maintenance, as
it reduces the risk of unexpected downtime and costly failures.
7. Reliability-Centered Maintenance (RCM) primarily focuses on:
a) Reducing labor costs
b) Ensuring safety, environmental compliance, and operational
continuity
c) Increasing inventory levels
d) Standardizing work schedules
b) Ensuring safety, environmental compliance, and operational
continuity
RCM is a structured approach to determine maintenance
strategies that protect safety, the environment, and production.
8. Which of the following is NOT a key element of a reliability
program?
a) Root cause analysis
b) Condition monitoring
c) Employee turnover tracking
d) Failure mode and effects analysis (FMEA)
c) Employee turnover tracking
Reliability programs focus on equipment and system performance,
not HR metrics.
9. Which failure analysis technique identifies all possible failure
modes and their impact?
a) Root cause analysis (RCA)
b) Failure Modes and Effects Analysis (FMEA)
c) Pareto analysis
d) Trend analysis
b) Failure Modes and Effects Analysis (FMEA)
, FMEA systematically evaluates potential failure modes, their
causes, and effects to prioritize corrective actions.
10. The primary purpose of root cause analysis (RCA) is to:
a) Assign blame for failures
b) Identify the underlying cause of a failure
c) Schedule maintenance tasks
d) Reduce operating costs
b) Identify the underlying cause of a failure
RCA looks beyond symptoms to prevent recurrence by addressing
the true cause of equipment problems.
11. Which of the following metrics indicates how often a system
fails during a specific period?
a) MTBF
b) MTTR
c) Failure rate
d) Reliability index
c) Failure rate
Failure rate measures the frequency of failures over time, helping
to assess system reliability.
12. Mean Time To Repair (MTTR) refers to:
a) Average time between failures
b) Average downtime to restore equipment to operation
c) Maintenance cost per hour
d) Average time equipment runs without repair
b) Average downtime to restore equipment to operation
MTTR measures the efficiency of maintenance teams in restoring
failed equipment.
13. Which of the following is a condition-based monitoring tool?
a) Thermography
