You've bored a large hole in a piece of wood to insert a doorknob. Which of these tools would you use to smooth the edges of the hole?
chisel |
|
rasp |
|
file |
|
plane |
Files consist of diagonal rows of fine teeth and are used for fine finishing work to smooth, polish, or shape objects. Rasps are files with larger teeth that are used for coarse finishing work. Both files and rasps are designed to be inserted into detachable handles.
Which of the following is not an advantage of using a ratchet with a larger point-sized socket?
larger point sizes allow easier alignment |
|
larger point sizes allow greater toque to be applied |
|
larger point sizes are stronger |
|
all of these are advantages of larger point sizes |
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.
Measuring tools provide a convenient and easy way to compare object dimensions against:
each other |
|
perfection |
|
a standard |
|
a drawing |
Measuring tools give easy access to the wide variety of standard dimensions that are used to categorize and classify objects.
Screwdrivers are most broadly classified by their:
torque |
|
tip |
|
width |
|
length |
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).
What is a caliper used for?
measuring thickness and irregular shapes |
|
ensuring that surfaces are level |
|
transferring distances between objects |
|
making perfectly vertical lines |
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.
