Inside and outside micrometers measure inside and outside:
angles |
|
tolerances |
|
lengths |
|
diameters |
Micrometers measure the diameter of cylindrical objects. Outside micrometers measure the external diameter of cylinders and inside micrometers measure the internal diameter of the cylinder's hole.
Which of the following saws would you use for creating a curved cut in wood?
hacksaw |
|
coping saw |
|
crosscut saw |
|
back saw |
Wood saws are categorized by their teeth shape and the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make. 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.
Which of the following statements about drill bits is not true?
drill bit size maxes out at ½" for metalworking |
|
drill bit size maxes out at ¼" for woodworking |
|
drill bits are primarily right-handed |
|
drill bits are primarily left-handed |
Drill bits remove material to create holes. They come in a variety of sizes, maxing out at ¼" for woodworking and ½" for metalworking. The majority of drill bits are right-handed which means they cut while rotating in a clockwise direction.
Which of the following is not a type of electric-arc welding?
stick |
|
oxyacetylene |
|
TIG |
|
MIG |
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 is not an advantage of using a tape measure over using a ruler?
measure in tighter spaces |
|
easier storage |
|
measure with more accuracy |
|
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.
