Causes of fault

What is the definition of a fault?

• A) An unexpected event in a system
• B) An intentional disruption of a system
• C) A deviation from normal system operation
• D) A systematic problem in a process

Which of the following is a common cause of faults in mechanical systems?

• B) Software failure
• C) Human error
• D) Corrosion

Which of the following is not a type of fault?

• A) Transient fault
• B) Permanent fault
• C) Random fault
• D) Intermittent fault

What is the difference between a permanent fault and a transient fault?

• A) A permanent fault lasts longer than a transient fault
• B) A transient fault occurs more frequently than a permanent fault
• C) A permanent fault can be repaired more easily than a transient fault
• D) A transient fault is caused by a human error, while a permanent fault is caused by natural factors

Which of the following is an example of a systemic fault?

• A) A broken cable
• B) A clogged pipe
• C) An overheating engine
• D) A leaking roof

What is the role of fault analysis in the maintenance of a system?

• A) To prevent faults from occurring
• B) To repair faults after they occur
• C) To detect faults before they cause problems
• D) To ignore faults until they become critical

Given a specific mechanical system, how would you identify potential fault sources?

• A) Analyze system performance data
• B) Ask the system operator for their opinion
• C) Inspect the system visually
• D) Randomly test different parts of the system

Which of the following methods can be used to mitigate the effects of a fault in a software system?

• A) Replace the entire system with a new one
• B) Install a backup power source
• C) Implement a fault-tolerant design
• D) Increase the system's processing speed

How would you prioritize faults in a given system based on their impact on system performance?

• A) Fix faults in the order they are discovered
• B) Fix the most severe faults first
• C) Fix the most recent faults first
• D) Fix the easiest faults first

Given a specific mechanical system, how would you diagnose the root cause of a fault?

• A) Inspect the system visually
• B) Perform a fault tree analysis
• C) Conduct a system performance test
• D) Randomly test different parts of the system
