Screwdrivers are most broadly classified by their:
length |
|
tip |
|
torque |
|
width |
Screwdrivers come in many different handle, shaft, and tip configurations for use in a wide variety of applications. Screwdrivers are classified by their tip which is shaped to fit a corresponding screw head. Common tips are slotted (flat) and Phillips (x-shaped).
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.
This tool is a(n) __________.
micrometer |
|
inside caliper |
|
vernier caliper |
|
outside caliper |
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 is not an advantage of using a tape measure over using a ruler?
measure in tighter spaces |
|
measure longer distances |
|
measure with more accuracy |
|
easier storage |
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.
What is a caliper used for?
transferring distances between objects |
|
ensuring that surfaces are level |
|
measuring thickness and irregular shapes |
|
making perfectly vertical lines |
