Which of the following is not a common pliers configuration?
adjustable joint |
|
wire |
|
locking |
|
needle nose |
Pliers are designed to provide a mechanical advantage, allowing the force of the hand's grip to be amplified and focused with precision. Pliers also allow finer control over objects that are too small to be manipulated by the fingers alone. The standard configuration is combination pliers which provide a fixed maximum jaw width. Other styles include adjustable joint pliers that allow selecting jaw width, needle nose pliers for holding small objects in tight spaces and locking pliers that will lock in place to hold or clamp objects together.
What is a caliper used for?
ensuring that surfaces are level |
|
measuring thickness and irregular shapes |
|
making perfectly vertical lines |
|
transferring distances between objects |
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.
Inside and outside micrometers measure inside and outside:
diameters |
|
lengths |
|
tolerances |
|
angles |
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 these saws is used with a miter box?
back saw |
|
crosscut saw |
|
rip saw |
|
hacksaw |
A miter box utlizes a back saw (a fine toothed saw with a rigid strip of steel opposite its blade edge) to make cuts in wood at a specified angle.
Which of the following saws is not good for cutting wood?
crosscut saw |
|
back saw |
|
ripsaw |
|
hacksaw |
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.
