ASVAB Shop Information Test 5 — Questions and Answers
Question 1: What does the hardness rating on a grinding wheel (such as 'A' for soft to 'Z' for hard) indicate?
- The abrasive material used in the wheel
- How firmly the abrasive grains are bonded (Correct answer)
- The maximum RPM the wheel can withstand
- The grit size of the abrasive particles
Correct answer: How firmly the abrasive grains are bonded
The hardness grade on a grinding wheel reflects the bond strength holding the abrasive grains — harder grades retain grains longer.
Question 2: When cutting with a hacksaw, the blade teeth should face:
- Toward the handle (backward)
- Away from the handle (forward) (Correct answer)
- Alternating directions on each side
- Perpendicular to the frame
Correct answer: Away from the handle (forward)
Hacksaw blades are installed with teeth pointing forward (away from the handle) so they cut on the push stroke.
Question 3: Which fastener type allows a joint to be disassembled and reassembled many times without losing holding strength?
- Common wire nail
- Wood screw (Correct answer)
- Corrugated fastener
- Staple
Correct answer: Wood screw
Wood screws can be driven in and removed repeatedly while maintaining their grip, making them ideal for assemblies that need disassembly.
Question 4: What is the purpose of a pilot hole when driving screws into hardwood?
- To add extra holding strength to the screw
- To prevent the wood from splitting and ease screw insertion (Correct answer)
- To countersink the screw head automatically
- To measure the correct screw length needed
Correct answer: To prevent the wood from splitting and ease screw insertion
A pilot hole slightly smaller than the screw shank relieves stress in the wood fibers, preventing splitting and reducing the torque needed.
Question 5: What is 'runout' in a drill press or lathe?
- The distance the tool travels before stopping
- The wobble or eccentricity of a rotating spindle or chuck (Correct answer)
- The speed at which metal shavings are removed
- The clearance angle on a cutting tool
Correct answer: The wobble or eccentricity of a rotating spindle or chuck
Runout is the deviation of a rotating tool or chuck from true center rotation, causing vibration and inaccurate holes or cuts.
Question 6: Which of the following best describes the purpose of a wire nut (twist connector)?
- To anchor a wire to a structural beam
- To join and insulate two or more electrical wires together (Correct answer)
- To measure the resistance of a circuit
- To strip insulation from wire ends
Correct answer: To join and insulate two or more electrical wires together
A wire nut is twisted onto stripped wire ends to mechanically connect and electrically insulate them without soldering.
Question 7: What type of wrench uses a non-slip grip that tightens around a fastener as more torque is applied?
- Combination wrench
- Pipe (Stillson) wrench (Correct answer)
- Box-end wrench
- Adjustable wrench
Correct answer: Pipe (Stillson) wrench
A pipe wrench has serrated jaws on a pivoting heel that grip tighter as turning force increases, designed for round pipe and fittings.
