What is a caliper used for?
measuring thickness and irregular shapes |
|
ensuring that surfaces are level |
|
making perfectly vertical lines |
|
transferring distances between objects |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
Which of the following saws would you use if you're cutting wood along the grain?
ripsaw |
|
crosscut saw |
|
hacksaw |
|
back saw |
The ripsaw delivers maximum efficiency at cutting with or along the grain (ripping).
Which of the following is not a type of electric-arc welding?
oxyacetylene |
|
stick |
|
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.
You are using a hacksaw to cut a Class 8 bolt. What is the most appropriate TPI for your saw blade?
10 TPI |
|
18 TPI |
|
2 TPI |
|
8 TPI |
A Class 8 bolt is made of very hard metal and larger TPI saw blades are most appropriate for very hard metals.
You need to secure a piece of wood while you're drilling a hole. Which of the following would be the most appropriate tool to use?
pincers |
|
clamp |
|
pliers |
|
vise |
A vise is a clamp that is anchored to a work station and designed to hold material in place while it is being operated upon.
