Which of the following would provide the most accurate measure of the diameter of a solid cylinder?
inside micrometer |
|
tape measure |
|
ruler |
|
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 saws would you use if you're cutting wood across the grain?
ripsaw |
|
back saw |
|
crosscut saw |
|
hacksaw |
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.
When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).
low |
|
odd |
|
even |
|
high |
Blades with more and smaller teeth (high TPI) cut harder metals more effectively while blades with fewer and larger teeth (low TPI) cut softer metals more effectively.
This tool is a(n) __________.
inside micrometer |
|
inside caliper |
|
vernier caliper |
|
outside caliper |
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.
