What is a micrometer used for?
transferring dimensions between objects |
|
measuring the diameter of cylindrical objects with high precision |
|
measuring length around corners |
|
ensuring that a surface is level |
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.
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?
pliers |
|
pincers |
|
vise |
|
clamp |
A vise is a clamp that is anchored to a work station and designed to hold material in place while it is being operated upon.
The primary difference between a claw and a ball-peen hammer is which of the following?
their size |
|
their non-striking end |
|
their striking end |
|
their handle shape |
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.
Inside and outside micrometers measure inside and outside:
angles |
|
diameters |
|
tolerances |
|
lengths |
Micrometers measure the diameter of cylindrical objects. Outside micrometers measure the external diameter of cylinders and inside micrometers measure the internal diameter of the cylinder's hole.
Which of the following statements about an 8-point saw is not true?
an 8-point saw has eight teeth per inch |
|
an 8-point saw makes a rougher cut than a 12-point saw |
|
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.
