What is a micrometer used for?
measuring the diameter of cylindrical objects with high precision |
|
ensuring that a surface is level |
|
transferring dimensions between objects |
|
measuring length around corners |
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.
This tool is a(n) __________.
outside caliper |
|
inside caliper |
|
vernier caliper |
|
outside 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 types of saws would you use if you needed to cut the wood quickly and weren't concerned with leaving rough edges?
rip saw |
|
coping saw |
|
crosscut saw |
|
hacksaw |
Wood saws are categorized primarily by their teeth. 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 statements about an 8-point saw is not true?
an 8-point saw makes a rougher cut than a 12-point saw |
|
an 8-point saw has eight teeth per inch |
|
an 8-point saw makes a rougher cut than a 6-point saw |
|
an 8-point saw makes a finer cut than a 12-point saw |
Saw blades are described by the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make.
