A dial indicator is used primarily to measure:
Answer: Small variations in surface position or runout
A dial indicator measures small deflections or runout relative to a reference point, not absolute dimensions.
Which of the following best describes a ball-peen hammer's secondary use beyond striking punches?
Answer: Peening and rounding metal rivet heads
The ball end is designed to peen (spread and shape) metal, particularly to mushroom rivet heads.
What does the term 'kerf' refer to when using a saw?
Answer: The width of the cut made by the blade
Kerf is the slot or gap left in the material after the saw blade passes through it, equal to the blade's tooth-set width.
A pipe wrench should NOT be used on:
Answer: Hex-shaped nuts and bolts
Pipe wrenches have serrated jaws designed for round pipe; using them on hex fasteners damages the corners.
Which soldering iron tip shape provides the best heat transfer for soldering large joints?
Answer: Chisel (flat) tip
A chisel tip has a larger contact surface area, transferring heat more efficiently to large solder joints.
An impact driver differs from a standard drill/driver primarily because it:
Answer: Delivers rotational impacts to prevent cam-out on fasteners
An impact driver uses a hammer-and-anvil mechanism to deliver concussive rotational blows, greatly reducing cam-out on stubborn fasteners.
What is the purpose of the adjustable shoe on a hand plane?
Answer: To control the thickness of the wood shaving removed
Adjusting the shoe (depth of cut) controls how deep the blade protrudes below the sole, determining shaving thickness.
