ANSWERS) Q&A 2026 |INSTANT DOWNLOAD PDF
1. What is the primary purpose of Lockout/Tagout (LOTO)
procedures in millwright work?
A. To increase machine speed
B. To prevent accidental machine startup during maintenance
C. To improve production output
D. To reduce tool wear
Correct Answer: B
Rationale: LOTO ensures machinery is properly isolated from
energy sources to prevent accidental energization and protect
workers during maintenance.
2. Which tool is most commonly used to measure internal and
external dimensions accurately?
A. Hammer
B. Vernier caliper
C. Wrench
D. File
Correct Answer: B
,Rationale: Vernier calipers measure inside, outside, and depth
dimensions with high precision.
3. What is the safest way to lift a heavy load using a crane?
A. Lift quickly to save time
B. Use improper slings for convenience
C. Follow rated load limits and proper rigging procedures
D. Stand under the load for guidance
Correct Answer: C
Rationale: Safe lifting requires proper rigging and adherence to
rated capacities to avoid accidents.
4. Which bearing type is designed to handle both radial and
axial loads?
A. Plain bearing
B. Ball bearing
C. Thrust bearing only
D. Sleeve bearing only
Correct Answer: B
Rationale: Ball bearings can support both radial and axial loads
efficiently.
5. What is the main purpose of lubrication in mechanical
systems?
,A. Increase noise
B. Reduce friction and wear
C. Increase heat generation
D. Slow machine operation
Correct Answer: B
Rationale: Lubrication reduces friction, heat, and wear
between moving parts.
6. Which blueprint line type represents hidden features?
A. Solid thick line
B. Dashed line
C. Zigzag line
D. Chain line
Correct Answer: B
Rationale: Hidden edges or components are shown using
dashed lines.
7. What is the function of a coupling in machinery?
A. Increase voltage
B. Connect two shafts to transmit power
C. Reduce lubrication
D. Stop machine vibration completely
Correct Answer: B
Rationale: Couplings connect rotating shafts to transmit
torque.
, 8. What safety equipment is required when grinding metal?
A. Sandals
B. Safety glasses
C. Loose gloves only
D. No protection needed
Correct Answer: B
Rationale: Eye protection is essential due to flying metal
particles.
9. Which drive system uses a flexible belt over pulleys?
A. Gear drive
B. Chain drive
C. Belt drive
D. Hydraulic drive
Correct Answer: C
Rationale: Belt drives transfer motion using flexible belts and
pulleys.
10. What is the purpose of shaft alignment?
A. Increase vibration
B. Reduce wear and improve efficiency
C. Decrease torque
D. Increase friction
