Question 1

What is the primary purpose of a torque wrench?

Accepted Answer

To apply a specific amount of rotational force to a fastener

Answer

A torque wrench is a precision tool that allows the user to apply a specific, measured amount of torque (rotational force) to a fastener, ensuring it is neither too loose nor overtightened, which is critical in engines and structural assemblies.

Question 2

Which type of saw is best suited for cutting curves and irregular shapes in wood?

Accepted Answer

Jigsaw

Answer

A jigsaw has a narrow, reciprocating blade that can pivot and follow curved or irregular cutting lines, making it the ideal choice when straight cuts are not required.

Question 3

What is a utility knife most commonly used for in mechanical and construction work?

Accepted Answer

Scoring or cutting soft materials like drywall, cardboard, and plastic sheeting

Answer

A utility knife features a retractable, replaceable blade designed for scoring and cutting soft or thin materials such as drywall, cardboard, rope, and plastic sheeting — not hard materials like metal or thick wood.

Question 4

What does a tap and die set allow a mechanic to do?

Accepted Answer

Cut or repair threads on bolts and in holes

Answer

A tap cuts internal threads inside a hole (so a bolt can screw in), while a die cuts external threads onto a rod or bolt. Together they allow mechanics to create new threads or restore damaged ones.

Question 5

Which hand tool is used to measure and mark a straight line at a precise right angle (90°) to an edge?

Accepted Answer

Combination square

Answer

A combination square has a ruler and a sliding head fixed at 90° (and often 45°), allowing the user to scribe accurate right-angle lines from any edge — essential for layout work in carpentry and metalworking.
