C: If two pieces to be joined by soldering are large, it may pay to tin the surfaces before attempting to join them. Heating the surfaces gently while applying flux to them, and then adding solder once the flux has thoroughly cleaned the material will accomplish this. Since soldering is the process involved, the correct answer is (C).
D: When large-diameter objects must be gripped or twisted, a technician would use adjustable joint pliers to get the job done. These are adjustable over a large range of sizes, as they have multiple “arc-joints” that the pliers can be set into. The handles are also very long, which gives very good leverage and makes for maximum gripping power. These pliers are also commonly known as water pump pliers or Channellock pliers. Since choice (D) allows for the tools in both choices (A) and (C), it is the correct answer.
D: The size of a socket for a given bolt head is determined by the distance between two parallel sides of the bolt head.
B: Whenever you see the words “force” and “wrench” in the same sentence, you should immediately think about torque, (B). You can think of torque as twisting motion, which is exactly what allows a fastener to be tightened or loosened. Don’t get torque confused with tension, (C), which instead is a pulling force associated with a weight on a string or wire.
A: A ball-peen hammer has one main benefit: it generally has a stronger head made of steel. This matches choice (A). Choice (B) more closely describes a mallet, certainly not a steel hammer, and choice (C) describes a benefit of a claw hammer, so that is the opposite of what you’re looking for. Finally, it makes little sense to talk about (D) leverage when discussing striking tools.
