-
Question 1 easy
Which tool is specifically designed to tighten or loosen hex-head bolts and nuts by applying torque?
Show answer & explanation
Correct answer: B — wrench
A wrench (or spanner) provides mechanical advantage and grip to turn nuts and bolts.
-
Question 2 easy
What handheld tool is used to make smooth, straight cuts across the grain of a wooden board?
Show answer & explanation
Correct answer: D — crosscut saw
A crosscut saw has bevel-edged teeth designed to cut cleanly across wood fibers without tearing.
-
Question 3 easy
What fastener is best suited for joining two pieces of metal together when access is only available from one side?
Show answer & explanation
Correct answer: A — pop rivet
Pop rivets (blind rivets) allow mechanical fastening when only one side of the joint is accessible.
-
Question 4 medium
What is the primary function of a claw hammer's curved tail opposite its striking face?
Show answer & explanation
Correct answer: C — extracting embedded nails from timber
The curved claw acts as a lever to hook under nail heads and pull them out of wood.
-
Question 5 medium
Before applying a coat of paint to a wooden surface that has been freshly patched with wood putty, what essential preparation step should be completed?
Show answer & explanation
Correct answer: A — sanding the dry putty flush with the surrounding wood
Sanding creates a seamless, smooth surface so the paint layer finishes evenly without showing patches.
-
Question 6 medium
Which type of woodworking joint utilizes interlocking finger-like projections at 90 degrees to create a strong corner joint for drawers and boxes?
Show answer & explanation
Correct answer: B — dovetail joint
Dovetail joints feature trapezoidal pins and tails that interlock, resisting mechanical pull forces from multiple directions.
-
Question 7 medium
Why does using a breaker bar with a long handle make loosening a rusted bolt easier than using a standard short ratchet?
Show answer & explanation
Correct answer: A — it increases torque by extending the distance from the pivot point
The reason lies in the principle of torque in Physics:
Torque = Applied Force (F) x Lever Arm (r)
Lever arm (r): The distance from the point where you pull to the center of the nut (the pivot point).
Torque: The force that rotates an object around an axis.
When a nut is rusted, the friction between the threads is very large, requiring a high torque to move the nut:
With a short ratchet wrench (standard short ratchet), the lever arm r is small. You have to use a lot of force (F) to generate enough torque.
With a long breaker bar, the lever arm r increases significantly. With the same pulling force from your hand, the torque generated at the head of the nut is much greater, helping to overcome the friction of rust more easily.

Question 8 hard
Which metal-joining process uses high heat to melt both base metals and a filler metal, fusing them together into a single continuous piece?
Show answer & explanation
Correct answer: C — welding
Welding melts base metals together for extreme strength, unlike soldering or brazing which only melt lower-melting-point filler alloys.
-
Question 9 hard
What specialty vise uses a heavy chain wrapped around a cylindrical object to securely clamp steel pipe for threading or cutting?
Show answer & explanation
Correct answer: D — chain pipe vise
Chain pipe vises wrap a high-tensile steel chain around round pipe stock to distribute clamping force evenly around the circumference.
-
Question 10 hard
Which specialized cutting tool features compound-hinged handles designed to exert extreme mechanical advantage to shear heavy steel chain links or rebar?
Show answer & explanation
Correct answer: A — bolt cutters
Bolt cutters utilize compound levers to multiply force from the handles to hard steel blades capable of cutting thick steel.
