Chapter 17 Maintenance and Reliability
17.1 End-of-Chapter Problems
1) The Pickering Nuclear Power Station in Ontario uses a proper maintenance management program, and
devotes significant dollar and labour resources to power plant maintenance, because the costs of
unexpected failure are incredibly high.
Answer: TRUE
Diff: 1 Type: TF
Skill: knowledge
Learning Outcome: LO1 Describe how to improve system reliability
2) Maintenance includes all activities involved in keeping a system's equipment in working order.
Answer: TRUE
Diff: 1 Type: TF
Skill: knowledge
Learning Outcome: LO1 Describe how to improve system reliability
3) Reliability is the probability that a machine part or product will function properly for a specified time
regardless of conditions.
Answer: FALSE
Diff: 1 Type: TF
Skill: knowledge
Learning Outcome: LO2 Determine system reliability
4) The product failure rate is the percentage of failures among the total number of products tested.
Answer: TRUE
Diff: 1 Type: TF
Skill: knowledge
Learning Outcome: LO1 Describe how to improve system reliability
5) The MTBF (mean time between failures) is calculated as the reciprocal of the number of failures during
a period of time.
Answer: TRUE
Diff: 2 Type: TF
Skill: comprehension
Learning Outcome: LO3 Determine mean time between failures (MTBF)
6) If the mean time between failures has been calculated to be 2,000 hours, then FR(N) = 0.0005
failures/unit-hour.
Answer: TRUE
Diff: 2 Type: TF
Skill: comprehension
Learning Outcome: LO3 Determine mean time between failures (MTBF)

, 7) The reliability of a system in which each individual component must function in order for the entire
system to function, and in which each component has its own unique reliability, independent of other
components, is the product of the probabilities of each of those components.
Answer: TRUE
Diff: 2 Type: TF
Skill: comprehension
Learning Outcome: LO2 Determine system reliability
8) Adding an additional part to a component or product ordinarily reduces reliability by introducing an
additional source of failure.
Answer: TRUE
Diff: 2 Type: TF
Skill: comprehension
Learning Outcome: LO2 Determine system reliability
9) A redundant part or component increases reliability because it is connected in parallel, not in series.
Answer: TRUE
Diff: 2 Type: TF
Skill: comprehension
Learning Outcome: LO2 Determine system reliability
10) A redundant part decreases reliability if the reliability of the redundant part is lower than that of the
part it is backing up.
Answer: FALSE
Diff: 2 Type: TF
Skill: comprehension
Learning Outcome: LO2 Determine system reliability
11) Preventive maintenance is reactive.
Answer: FALSE
Diff: 1 Type: TF
Skill: knowledge
Learning Outcome: LO4 Distinguish between preventive and breakdown maintenance
12) Preventive maintenance is nothing more than keeping the equipment and machinery running.
Answer: FALSE
Diff: 1 Type: TF
Skill: knowledge
Learning Outcome: LO4 Distinguish between preventive and breakdown maintenance
13) Preventive maintenance implies that we can determine when a system needs service or will need
repair.
Answer: TRUE
Diff: 1 Type: TF
Skill: knowledge
Learning Outcome: LO4 Distinguish between preventive and breakdown maintenance
