1. What is the primary responsibility of an industrial mechanic in a
manufacturing facility?
A. Designing new production products
B. Installing, maintaining, troubleshooting, and repairing industrial
equipment
C. Managing employee payroll records
D. Performing only electrical wiring installations
Answer: B. Installing, maintaining, troubleshooting, and repairing
industrial equipment
Rationale: Industrial mechanics are responsible for keeping
machinery operating safely and efficiently through preventive
maintenance, diagnostics, repairs, and equipment installation. Their
role combines mechanical skills, troubleshooting ability, and
knowledge of industrial systems.
2. Which type of maintenance is performed before equipment
failure occurs?
A. Corrective maintenance
B. Emergency maintenance
1
,C. Preventive maintenance
D. Breakdown maintenance
Answer: C. Preventive maintenance
Rationale: Preventive maintenance involves scheduled inspections,
lubrication, adjustments, and part replacements designed to prevent
unexpected equipment failures and extend machine life.
3. What is the purpose of a lockout/tagout (LOTO) procedure?
A. Increase machine operating speed
B. Prevent unauthorized machine use during maintenance
C. Reduce lubrication requirements
D. Improve product quality
Answer: B. Prevent unauthorized machine use during maintenance
Rationale: Lockout/tagout procedures isolate hazardous energy
sources so machinery cannot accidentally start while workers are
performing maintenance or repairs.
4. Which tool is commonly used to measure the diameter of a
precision machine component?
A. Pipe wrench
B. Vernier caliper
C. Hammer
D. Adjustable wrench
Answer: B. Vernier caliper
Rationale: Vernier calipers provide accurate measurements of inside,
outside, depth, and step dimensions of mechanical components.

,5. What is the main function of a bearing in rotating machinery?
A. Increase friction
B. Support rotating shafts and reduce friction
C. Generate electrical power
D. Increase vibration
Answer: B. Support rotating shafts and reduce friction
Rationale: Bearings allow shafts and rotating components to move
smoothly while minimizing friction, heat generation, and wear.
6. Excessive vibration in rotating equipment is commonly caused by:
A. Proper alignment
B. Shaft misalignment or imbalance
C. Correct lubrication
D. Proper installation
Answer: B. Shaft misalignment or imbalance
Rationale: Mechanical imbalance, coupling misalignment, worn
bearings, and loose components are frequent causes of industrial
equipment vibration.
7. What instrument is used to measure electrical resistance?
A. Voltmeter
B. Ammeter
C. Ohmmeter
D. Tachometer
Answer: C. Ohmmeter
Rationale: An ohmmeter measures resistance in ohms and is
commonly used for testing electrical circuits and components.
3
, 8. A hydraulic system primarily uses what medium to transmit
power?
A. Compressed air
B. Hydraulic fluid
C. Steam
D. Mechanical springs
Answer: B. Hydraulic fluid
Rationale: Hydraulic systems use pressurized fluid to transmit force,
allowing machines to perform heavy-duty operations such as lifting
and pressing.
9. What is cavitation in a hydraulic pump?
A. Excessive electrical current
B. Formation and collapse of vapor bubbles in fluid
C. Proper lubrication process
D. Shaft alignment procedure
Answer: B. Formation and collapse of vapor bubbles in fluid
Rationale: Cavitation occurs when low pressure causes vapor bubbles
to form and collapse, damaging pump components and reducing
efficiency.
10. Which component converts hydraulic energy into mechanical
motion?
A. Hydraulic actuator
B. Filter
