1. What is the primary purpose of preventive maintenance?
A. To eliminate all equipment failures
B. To reduce the likelihood of unexpected equipment failure
C. To increase equipment operating temperature
D. To avoid keeping maintenance records
Answer: B. To reduce the likelihood of unexpected equipment
failure
Rationale: Preventive maintenance uses scheduled inspections,
servicing, adjustment, and replacement to reduce failures and
extend equipment life.
2. Which maintenance strategy is based on monitoring actual
equipment condition?
A. Corrective maintenance
B. Run-to-failure maintenance
C. Predictive maintenance
D. Emergency maintenance
,Answer: C. Predictive maintenance
Rationale: Predictive maintenance uses condition-monitoring
techniques such as vibration analysis, thermography, and oil
analysis.
3. What should be done before servicing energized industrial
equipment?
A. Increase the equipment speed
B. Apply lockout/tagout procedures
C. Remove all warning labels
D. Start the equipment remotely
Answer: B. Apply lockout/tagout procedures
Rationale: Lockout/tagout controls hazardous energy and helps
prevent unexpected startup during maintenance.
4. Which device is commonly used to measure electrical
resistance?
A. Ammeter
B. Voltmeter
C. Ohmmeter
D. Tachometer
Answer: C. Ohmmeter
Rationale: An ohmmeter measures resistance, normally in
ohms.
,5. What is the SI unit of electrical current?
A. Volt
B. Watt
C. Ohm
D. Ampere
Answer: D. Ampere
Rationale: Electrical current is measured in amperes (A).
6. According to Ohm's law, voltage equals:
A. Current divided by resistance
B. Current multiplied by resistance
C. Resistance divided by current
D. Power multiplied by resistance
Answer: B. Current multiplied by resistance
Rationale: Ohm's law is expressed as V = I × R.
7. Which tool is best suited for accurately measuring the
outside diameter of a shaft?
A. Pipe wrench
B. Micrometer
C. Cold chisel
D. Level
, Answer: B. Micrometer
Rationale: A micrometer provides highly accurate dimensional
measurements of shafts and other components.
8. What is the main purpose of a bearing?
A. Increase friction
B. Support moving components and reduce friction
C. Increase electrical resistance
D. Store compressed air
Answer: B. Support moving components and reduce friction
Rationale: Bearings support rotating or moving parts while
minimizing friction and wear.
9. What is a common indication of bearing failure?
A. Reduced noise
B. Increased vibration and temperature
C. Lower friction
D. Improved alignment
Answer: B. Increased vibration and temperature
Rationale: Excessive vibration, heat, noise, and abnormal
lubrication conditions are common signs of bearing problems.
10. What is shaft alignment intended to accomplish?
