1. Which of the following is the primary purpose of a maintenance
schedule?
a) To increase downtime
b) To prevent equipment failure
c) To increase production speed
d) To reduce employee workload
Rationale: A maintenance schedule helps prevent unexpected
equipment failures, ensuring operational efficiency.
2. What type of lubrication is best for high-speed rotating machinery?
a) Grease
, b) Oil
c) Water
d) Graphite powder
Rationale: Oil reduces friction in high-speed applications more
effectively than grease, which is better for slower speeds.
3. A multimeter is used to measure:
a) Voltage, current, and resistance
b) Temperature only
c) Pressure only
d) Flow rate only
Rationale: Multimeters are versatile tools used to measure electrical
parameters such as voltage, current, and resistance.
4. Which of the following is a common symptom of a failing bearing?
a) Smooth operation
b) Low noise
c) Excessive vibration and heat
d) Reduced load
Rationale: Worn bearings typically produce vibration and heat due to
increased friction.
5. What is the main purpose of a lockout/tagout procedure?
a) To increase productivity
b) To ensure equipment is safely de-energized before maintenance
c) To speed up repair work
, d) To reduce material costs
Rationale: Lockout/tagout procedures prevent accidental equipment
energization during maintenance.
6. Which of the following is NOT a type of pump commonly used in
industrial maintenance?
a) Centrifugal pump
b) Positive displacement pump
c) Diaphragm pump
d) Combustion pump
Rationale: Combustion pump is not a recognized pump type; the
others are standard in industrial systems.
7. What is the main purpose of a V-belt in machinery?
a) Increase heat
b) Reduce noise
c) Transmit mechanical power between pulleys
d) Measure torque
Rationale: V-belts are designed to transfer mechanical power
efficiently between shafts.
8. In electrical systems, a short circuit causes:
a) Reduced current flow
b) Excessive current flow
c) No change in current
d) Gradual voltage increase
, Rationale: A short circuit provides a low-resistance path, leading to
high current that can cause damage.
9. What does the term "PM" stand for in maintenance?
a) Product Manufacturing
b) Preventive Maintenance
c) Performance Monitoring
d) Production Manual
Rationale: PM refers to scheduled maintenance performed to
prevent equipment failure.
10. Which tool is most appropriate for aligning a motor shaft to a
pump shaft?
a) Hammer
b) Screwdriver
c) Dial indicator
d) Wrench
Rationale: Dial indicators accurately measure shaft alignment,
ensuring proper coupling.
11. What is the function of a pressure relief valve?
a) Increase system pressure
b) Prevent overpressure in a system
c) Reduce flow
d) Convert pressure to temperature
