What is a caliper used for?
transferring distances between objects |
|
making perfectly vertical lines |
|
measuring thickness and irregular shapes |
|
ensuring that surfaces are level |
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.
This tool is a(n) __________.
adjustable wrench |
|
combination wrench |
|
open-end wrench |
|
box-end wrench |
Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.
When using a hacksaw, blades with __________ teeth are more appropriate for cutting thinner materials.
less |
|
more |
|
wider |
|
thinner |
A hacksaw has replaceable blades and is used to cut metal. The blade type is chosen based on the material that is to be cut. Blades with larger numbers of teeth per inch are more appropriate for cutting thinner materials.
Which of the following would provide the most accurate measure of the diameter of a solid cylinder?
ruler |
|
inside micrometer |
|
tape measure |
|
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 standard |
|
a drawing |
|
perfection |
Measuring tools give easy access to the wide variety of standard dimensions that are used to categorize and classify objects.
