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.
Measuring tools provide a convenient and easy way to compare object dimensions against:
each other |
|
a drawing |
|
a standard |
|
perfection |
Measuring tools give easy access to the wide variety of standard dimensions that are used to categorize and classify objects.
Which of the following is not an advantage of using a tape measure over using a ruler?
measure in tighter spaces |
|
measure longer distances |
|
easier storage |
|
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.
This tool is a(n) __________.
lever |
|
chisel |
|
punch |
|
screwdriver |
A chisel has a long sharp edge and is used, often in conjunction with a hammer, for cutting. In woodworking, chisels are used to remove large sections of wood to create the initial shape of a design. In metalworking, chisels are used to remove waste metal when a smooth finish is not required.
Which of the following determines whether a socket can be used with a particular ratchet?
the drive circumference |
|
the drive size |
|
the point size |
|
the socket size |
A ratchet (or socket wrench) is a wrench that applies torque in only one direction with a handle that can be moved back and forth without losing contact with the fastener. A ratchet uses variable attachments called sockets which come in a variety of drive sizes based on the size of the opening that attaches to the ratchet. Sockets with the same drive size will vary in the shape (six-point, twelve-point) and size of the nut opening that attaches to the fastener being tightened or loosened. Smaller point sized sockets are stronger and can apply greater torque while larger point sizes allow easier alignment.
