Millwright Journeyman Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf
- What is the primary purpose of a hoist in industrial applications?
- To lubricate machinery
- To lift and move heavy loads
- To cut metal
- To measure vibrations
- 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.
- Which type of bearing is typically used to support radial and axial
- Sleeve bearing
- Ball bearing 1 / 4
loads?
- Roller bearing
- Needle bearing
- Roller bearing
Rationale: Roller bearings are suitable for supporting both radial and axial
loads due to their cylindrical shape and load distribution properties.
- What is the purpose of a shim in machinery alignment?
- To measure temperature
- To provide electrical insulation
- To adjust and correct alignment
- To lubricate moving parts
- 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.
- When performing a shaft alignment, which tool is commonly used?
- Torque wrench
- Dial indicator
- Caliper
- Micrometer
- Dial indicator
Rationale: Dial indicators are precise instruments used to measure
misalignment and ensure correct alignment of shafts. 2 / 4
- What is the main function of a coupling?
- To connect two rotating shafts
- To control speed
- To transmit electrical signals
- To support bearings
- To connect two rotating shafts
Rationale: Couplings join two shafts together to transmit torque and
accommodate minor misalignment.
- In vibration analysis, what does an increase in amplitude typically
- Proper lubrication
- Imbalance or misalignment
- Normal operation
- Correct installation
- Imbalance or misalignment
indicate?
Rationale: Excessive vibration amplitude often indicates mechanical issues
such as imbalance, misalignment, or bearing wear.
- What type of fit allows easy assembly and disassembly of parts?
- Interference fit
- Clearance fit
- Press fit
- Transition fit 3 / 4
- Clearance fit
Rationale: Clearance fits provide a small gap between parts, allowing easy
assembly and disassembly without force.
- Which welding process is commonly used for repairing millwright
- Shielded Metal Arc Welding (SMAW)
- Gas Welding
- Soldering
- Brazing
- Shielded Metal Arc Welding (SMAW)
machinery?
Rationale: SMAW is widely used in field repairs for its portability and
ability to weld a variety of metals.
- What is the purpose of a torque wrench in millwright work?
- To measure rotation speed
- To tighten fasteners to a specific torque
- To align shafts
- To measure vibration
- To tighten fasteners to a specific torque
Rationale: Torque wrenches ensure bolts and nuts are tightened to
manufacturer specifications, preventing over- or under-tightening.
- Which lubricant is best suited for high-speed, low-load
- / 4
applications?
