Which of the following is not an aspect of the mechanical advantage of pliers?
amplify hand grip force |
|
provide precision for manipulating small objects |
|
change the direction of hand grip force |
|
focus hand grip force |
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.
These tools are called:
chisels |
|
planes |
|
rasps |
|
files |
Wood chisels are used to shape or smooth wood surfaces. They come in a variety of widths and can be used with hand power or tapped with a mallet when deeper cuts need to be made.
This tool is a(n) __________.
vernier caliper |
|
outside micrometer |
|
outside caliper |
|
inside 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.
What is a caliper used for?
making perfectly vertical lines |
|
transferring distances between objects |
|
ensuring that surfaces are level |
|
measuring thickness and irregular shapes |

Screwdrivers are most broadly classified by their:
torque |
|
length |
|
width |
|
tip |
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).
