B. Supervising repair and maintenance of mechanical equipment
C. Performing financial audits
D. Writing software for machinery
B
The supervisor’s main role is overseeing maintenance and repair
operations for mechanical equipment.
2. What is the safest way to lift a heavy piece of equipment?
A. Use a forklift or hoist rated for the weight
B. Lift it manually with two people
C. Push it across the floor
D. Tilt it onto its side and drag it
A
Using equipment rated for the weight reduces the risk of injury
and equipment damage.
,3. Which of the following tools is used to measure rotational speed
of a motor?
A. Tachometer
B. Voltmeter
C. Thermometer
D. Manometer
A
A tachometer measures RPM (revolutions per minute) of rotating
machinery.
4. When a mechanical system is experiencing overheating, the first
step is to:
A. Increase load immediately
B. Shut down the system safely and inspect
C. Replace the system entirely
D. Ignore it until failure occurs
B
Overheating can indicate a serious problem; safe shutdown
prevents further damage.
5. In preventive maintenance, which of the following is most
important?
A. Waiting until equipment breaks
B. Regular inspection and servicing according to schedule
C. Only repairing visible damage
D. Replacing equipment regardless of condition
B
Preventive maintenance is based on regular inspections and
servicing to prevent failures.
,6. OSHA regulations require mechanical equipment supervisors to
ensure:

B. Safe working conditions and proper training for all staff
C. Maximum production at all times
D. Use of personal judgment over safety rules
B
OSHA standards prioritize safety and training for all personnel
handling machinery.
7. A hydraulic press is making unusual noises. The best immediate
action is to:
A. Continue operation until the end of shift
B. Shut down and inspect for hydraulic fluid leaks or worn
components
C. Lubricate it while running
D. Increase pressure to compensate
B
Unusual noises often indicate a mechanical issue that could be
dangerous.
8. When maintaining steam boilers, water levels should be checked:
A. Once a month
B. Daily, or as specified by operational guidelines
C. Only when the system fails
D. Weekly
B
Boiler water levels are critical to safe operation; regular

Class C extinguishers are designed for fires involving electrical
equipment.
10. The main purpose of a lubrication schedule is to:
A. Increase machine speed
B. Reduce friction and wear
C. Decrease operational cost only
D. Replace damaged parts
B
Lubrication prevents wear on moving parts and extends
equipment lifespan.
11. Vibration analysis is used primarily to:
A. Detect wear or imbalance in rotating machinery
B. Increase machine output
C. Measure temperature
D. Identify electrical faults
A
Vibration monitoring can detect early signs of mechanical issues
before failure occurs.
12. Which of the following indicates a properly functioning
pump system?
