Which of the following saws would you use if you're cutting wood along the grain?
hacksaw |
|
ripsaw |
|
crosscut saw |
|
back saw |
The ripsaw delivers maximum efficiency at cutting with or along the grain (ripping).
Which of the following statemements about chucks is not true?
a chuck's size indicates the largest diameter drill bit that will fit |
|
a chuck's size indicates the largest circumference drill bit that will fit |
|
electric drills utilize a chuck to hold the drill bit |
|
a chuck is tightened and loosened using a chuck key |
Electric drills utilize a chuck to hold the drill bit. A chuck's size indicates the largest diameter drill bit that will fit. A chuck is tightened and loosened using a chuck key.
Which of the following is not a common pliers configuration?
adjustable joint |
|
locking |
|
wire |
|
needle nose |
Pliers are designed to provide a mechanical advantage, allowing the force of the hand's grip to be amplified and focused with precision. Pliers also allow finer control over objects that are too small to be manipulated by the fingers alone. The standard configuration is combination pliers which provide a fixed maximum jaw width. Other styles include adjustable joint pliers that allow selecting jaw width, needle nose pliers for holding small objects in tight spaces and locking pliers that will lock in place to hold or clamp objects together.
Which of the following statements about welding is not true?
no filler metal is required when welding |
|
electric-arc welding is safer than oxyacetylene welding |
|
a weld can often be stronger than the base materials alone |
|
welding is done at higher temperatures than soldering |
Welding is a high-temperature process that involves melting the base metals in the objects to be joined to fuse them together. A filler metal is used to provide additional material to make up a joint that, depending on the weld type, can be stronger than the base materials alone. Oxyacetylene welding is a welding process that uses a torch fueled with oxygen and acetylene gases. Electric-arc welding utlizes electric current in a safer welding process (it doesn't involve burning explosive gases) that enables a wide variety of specialized applications like stick, MIG (metal inert gas), and TIG (tungsten inert gas) welding.
Which of the following determines whether a socket can be used with a particular ratchet?
the point size |
|
the drive circumference |
|
the drive size |
|
the socket size |
A ratchet (or socket wrench) is a wrench that applies torque in only one direction with a handle that can be moved back and forth without losing contact with the fastener. A ratchet uses variable attachments called sockets which come in a variety of drive sizes based on the size of the opening that attaches to the ratchet. Sockets with the same drive size will vary in the shape (six-point, twelve-point) and size of the nut opening that attaches to the fastener being tightened or loosened. Smaller point sized sockets are stronger and can apply greater torque while larger point sizes allow easier alignment.
