AIT Tools & Equipment 1 — Questions and Answers
Question 1: What is the primary purpose of a torque wrench?
- To tighten fasteners to a specific rotational force (Correct answer)
- To loosen rusted or seized bolts
- To measure the diameter of a bolt
- To cut threaded fasteners to length
Correct answer: To tighten fasteners to a specific rotational force
A torque wrench is designed to apply a precise, measurable amount of rotational force (torque) to fasteners, ensuring proper clamping without over- or under-tightening.
Question 2: Which screwdriver type is designed for screws with a cross-shaped recess?
- Flathead
- Phillips (Correct answer)
- Torx
- Allen (hex)
Correct answer: Phillips
Phillips screwdrivers have a cross-shaped tip engineered to fit the corresponding cross-shaped recess of Phillips head screws, providing better torque transfer than flathead designs.
Question 3: When using a hacksaw to cut metal, on which stroke should cutting pressure be applied?
- The back (pull) stroke only
- The forward (push) stroke only (Correct answer)
- Equal pressure on both strokes
- Short rapid strokes with no directional preference
Correct answer: The forward (push) stroke only
Hacksaw teeth are angled to cut on the forward stroke, so pressure should be applied pushing forward and released on the return stroke to prevent blade damage and improve efficiency.
Question 4: A combination square is primarily used to:
- Measure pipe diameters
- Mark and verify 90-degree and 45-degree angles (Correct answer)
- Cut metal at precise angles
- Tighten square-head bolts
Correct answer: Mark and verify 90-degree and 45-degree angles
A combination square can mark and verify both 90-degree (perpendicular) and 45-degree angles, making it a versatile layout tool for trades work.
Question 5: Which hand tool is designed to shave thin layers from wood to create a flat, smooth surface?
- Wood chisel
- Hand plane (Correct answer)
- Drawknife
- Card scraper
Correct answer: Hand plane
A hand plane uses a blade set at an angle within a flat body to remove thin, controlled shavings from wood surfaces, producing a flat and smooth finish.
Question 6: Proper hammering technique involves generating force from:
- The wrist only, keeping the arm rigid
- The elbow only, with the wrist locked
- A combination of wrist, elbow, and shoulder movement (Correct answer)
- The shoulder only, with a straight arm
Correct answer: A combination of wrist, elbow, and shoulder movement
Correct hammering technique uses coordinated movement from the wrist, elbow, and shoulder to deliver controlled force while reducing fatigue and preventing repetitive strain injuries.
Question 7: In the American Wire Gauge (AWG) system, what does a lower gauge number indicate?
- A thinner wire
- A thicker wire (Correct answer)
- Higher electrical resistance
- Shorter maximum wire length
Correct answer: A thicker wire
In the AWG system, lower gauge numbers correspond to thicker (larger diameter) wire, so a 10-gauge wire is thicker than a 12-gauge wire.
