electric drills utilize a chuck to hold the drill bit |
|
a chuck's size indicates the largest circumference drill bit that will fit |
|
a chuck is tightened and loosened using a chuck key |
|
a chuck's size indicates the largest diameter drill bit that will fit |
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.
Inside and outside micrometers measure inside and outside:
lengths |
|
diameters |
|
angles |
|
tolerances |
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 these saws is used with a miter box?
rip saw |
|
hacksaw |
|
back saw |
|
crosscut saw |
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 saws would you use if you're cutting wood across the grain?
back saw |
|
crosscut saw |
|
hacksaw |
|
ripsaw |
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 is not a type of electric-arc welding?
oxyacetylene |
|
TIG |
|
MIG |
|
stick |
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.
