Which of the following would be used to make a drilling guide mark in a sheet of metal?
screwdriver |
|
chisel |
|
center punch |
|
pin punch |
A punch is narrow and is used to drive objects like nails (pin punch) or for making guide marks for drilling (center punch) or patterns in wood or metal.
An arc-welder creates heat using:
propane |
|
oxyacetylene |
|
natural gas |
|
high voltage electricity |
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?
hacksaw |
|
crosscut saw |
|
back saw |
|
rip 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.
What is a caliper used for?
transferring distances between objects |
|
making perfectly vertical lines |
|
ensuring that surfaces are level |
|
measuring thickness and irregular shapes |
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.
The primary difference between a claw and a ball-peen hammer is which of the following?
their non-striking end |
|
their striking end |
|
their handle shape |
|
their size |
The most common striking tool is the hammer and the most common variety of hammer is the claw hammer. The claw hammer has two ends, one to drive nails and one to remove nails. Ball-peen hammers replace the claw with a rounded end that's used to round off the edges of metal pins and make gaskets.
