This tool is a(n) __________.
outside caliper |
|
inside caliper |
|
inside micrometer |
|
outside micrometer |
Micrometers provide accuracy to the thousandths of an inch and come in outside and inside varieties. An outside micrometer is used to measure outside thickness, such as the diameter of a bolt, while an inside micrometer is used to measure the inside dimension of an object, such as the diameter of the hole of a nut or the width of a channel.
Which of the following is not an advantage of using a tape measure over using a ruler?
measure with more accuracy |
|
easier storage |
|
measure longer distances |
|
measure in tighter spaces |
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.
This tool is a(n) __________.
outside caliper |
|
vernier caliper |
|
inside caliper |
|
inside micrometer |
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 for creating a curved cut in wood?
hacksaw |
|
back saw |
|
coping saw |
|
crosscut 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.
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 |
|
