screwdriver |
|
pin punch |
|
chisel |
|

Which of the following is not an advantage of using a tape measure over using a ruler?
measure in tighter spaces |
|
easier storage |
|
measure longer distances |
|
measure with more accuracy |
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.
These tools are called:
rasps |
|
files |
|
planes |
|
chisels |
Wood chisels are used to shape or smooth wood surfaces. They come in a variety of widths and can be used with hand power or tapped with a mallet when deeper cuts need to be made.
Which of the following saws would you use if you're cutting wood across the grain?
crosscut saw |
|
ripsaw |
|
hacksaw |
|
back 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.
Which of the following would provide the most accurate measure of the diameter of a solid cylinder?
inside micrometer |
|
outside micrometer |
|
ruler |
|
tape measure |
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.
