Question 1: Which type of wrench is specifically designed to tighten or loosen fasteners to a precise torque specification?
- Torque wrench (Correct answer)
- Box-end wrench
- Pipe wrench
- Adjustable wrench
Correct answer: Torque wrench
A torque wrench features a calibrated scale or digital readout that allows the user to apply a specific amount of rotational force to a fastener.
Question 2: What is the primary purpose of a ball-peen hammer?
- Driving finishing nails flush
- Shaping and peening metal (Correct answer)
- Pulling nails from wood
- Breaking apart concrete
Correct answer: Shaping and peening metal
A ball-peen hammer has a rounded head opposite the flat face, specifically designed for shaping sheet metal, setting rivets, and peening surfaces.
Question 3: When using a hacksaw to cut through a metal pipe, which direction should the teeth face?
- Toward the handle
- Away from the handle, pointing forward (Correct answer)
- Alternating directions
- It does not matter
Correct answer: Away from the handle, pointing forward
Hacksaw teeth should point away from the handle so the blade cuts on the forward push stroke, which provides better control and cutting efficiency.
Question 4: Which tool would be most appropriate for measuring the inside diameter of a cylindrical bore with high precision?
- Outside micrometer
- Telescoping gauge or inside micrometer (Correct answer)
- Steel ruler
- Combination square
Correct answer: Telescoping gauge or inside micrometer
A telescoping gauge or inside micrometer is designed to measure internal dimensions of holes and bores with precision down to thousandths of an inch.
Question 5: What safety precaution must always be followed when using a bench grinder?
- Wear leather gloves to grip the workpiece
- Stand to the side during initial startup and wear eye protection (Correct answer)
- Keep the tool rest at least 3 inches from the wheel
- Run the grinder at its lowest speed setting only
Correct answer: Stand to the side during initial startup and wear eye protection
Standing to the side during startup protects the operator in case the wheel shatters, and eye protection guards against flying sparks and debris.
Question 6: Which type of pliers features long, narrow jaws angled at the tip, making them ideal for reaching into tight electrical enclosures?
- Slip-joint pliers
- Locking pliers
- Bent-nose pliers (Correct answer)
- Channel-lock pliers
Correct answer: Bent-nose pliers
Bent-nose pliers have angled, tapered jaws that allow access to confined spaces and awkward angles commonly found in electrical and electronics work.
