This tool is a(n) __________.
combination wrench |
|
adjustable wrench |
|
box-end wrench |
|
open-end wrench |
Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.
A joint created by soldering is:
stronger than a weld |
|
weaker than a weld |
|
as strong as a weld |
|
as strong as the original metal |
A joint created by soldering is not as strong as a weld and not as strong as the original metal.
Which of the following is not an advantage of using a tape measure over using a ruler?
measure longer distances |
|
measure with more accuracy |
|
easier storage |
|
measure in tighter spaces |
Rulers are used to both measure distance and to draw straight lines. Tape measures are flexible rulers useful for measuring longer distances and in tighter spaces. Rulers and tape measures provide similarly accurate measurements.
Which of the following statements about welding is not true?
a weld can often be stronger than the base materials alone |
|
welding is done at higher temperatures than soldering |
|
electric-arc welding is safer than oxyacetylene welding |
|
no filler metal is required when welding |
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 types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?
hacksaw |
|
crosscut saw |
|
coping saw |
|
rip saw |
Wood saws are categorized primarily by their teeth. Crosscut saws utilize knife-shaped teeth that cut across the grain of the wood while rip saws cut with the grain using chisel-shaped teeth that rip the wood cells apart as the cut is made. The kerf (slot) made by by a crosscut saw is much smoother than that made by a rip saw but a rip saw cuts much faster. Coping saws are a type of bow saw used to make detailed often curving cuts using replaceable blades with fine small teeth.
