Which of the following saws would you use if you're cutting wood along the grain?
ripsaw |
|
hacksaw |
|
crosscut saw |
|
back saw |
The ripsaw delivers maximum efficiency at cutting with or along the grain (ripping).
An arc-welder creates heat using:
oxyacetylene |
|
natural gas |
|
high voltage electricity |
|
propane |
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 these saws is used with a miter box?
rip saw |
|
back saw |
|
crosscut saw |
|
hacksaw |
A miter box utlizes a back saw (a fine toothed saw with a rigid strip of steel opposite its blade edge) to make cuts in wood at a specified angle.
Which of the following is not an advantage of using a tape measure over using a ruler?
measure with more accuracy |
|
easier storage |
|
measure in tighter spaces |
|
measure longer distances |
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?
no filler metal is required when welding |
|
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 |
