1. What is the primary purpose of a hoist in industrial applications?
A. To lubricate machinery
B. To lift and move heavy loads
C. To cut metal
D. To measure vibrations
B. To lift and move heavy loads
Rationale: Hoists are designed to lift, lower, and move heavy loads safely,
which is a core function in millwright work.
2. Which type of bearing is typically used to support radial and axial
loads?
A. Sleeve bearing
B. Ball bearing
, C. Roller bearing
D. Needle bearing
C. Roller bearing
Rationale: Roller bearings are suitable for supporting both radial and axial
loads due to their cylindrical shape and load distribution properties.
3. What is the purpose of a shim in machinery alignment?
A. To measure temperature
B. To provide electrical insulation
C. To adjust and correct alignment
D. To lubricate moving parts
C. To adjust and correct alignment
Rationale: Shims are thin pieces of material used to fill gaps or spaces,
helping ensure proper alignment of machinery components.
4. When performing a shaft alignment, which tool is commonly used?
A. Torque wrench
B. Dial indicator
C. Caliper
D. Micrometer
B. Dial indicator
Rationale: Dial indicators are precise instruments used to measure
misalignment and ensure correct alignment of shafts.
, 5. What is the main function of a coupling?
A. To connect two rotating shafts
B. To control speed
C. To transmit electrical signals
D. To support bearings
A. To connect two rotating shafts
Rationale: Couplings join two shafts together to transmit torque and
accommodate minor misalignment.
6. In vibration analysis, what does an increase in amplitude typically
indicate?
A. Proper lubrication
B. Imbalance or misalignment
C. Normal operation
D. Correct installation
B. Imbalance or misalignment
Rationale: Excessive vibration amplitude often indicates mechanical issues
such as imbalance, misalignment, or bearing wear.
7. What type of fit allows easy assembly and disassembly of parts?
A. Interference fit
B. Clearance fit
C. Press fit
D. Transition fit
, B. Clearance fit
Rationale: Clearance fits provide a small gap between parts, allowing easy
assembly and disassembly without force.
8. Which welding process is commonly used for repairing millwright
machinery?
A. Shielded Metal Arc Welding (SMAW)
B. Gas Welding
C. Soldering
D. Brazing
A. Shielded Metal Arc Welding (SMAW)
Rationale: SMAW is widely used in field repairs for its portability and
ability to weld a variety of metals.
9. What is the purpose of a torque wrench in millwright work?
A. To measure rotation speed
B. To tighten fasteners to a specific torque
C. To align shafts
D. To measure vibration
B. To tighten fasteners to a specific torque
Rationale: Torque wrenches ensure bolts and nuts are tightened to
manufacturer specifications, preventing over- or under-tightening.
10. Which lubricant is best suited for high-speed, low-load
applications?
