Which of the following is not an aspect of the mechanical advantage of pliers?
change the direction of hand grip force |
|
provide precision for manipulating small objects |
|
focus hand grip force |
|
amplify 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.
You need to secure a piece of wood while you're drilling a hole. Which of the following would be the most appropriate tool to use?
vise |
|
clamp |
|
pliers |
|
pincers |
A vise is a clamp that is anchored to a work station and designed to hold material in place while it is being operated upon.
This tool is a(n) __________.
inside caliper |
|
outside caliper |
|
outside micrometer |
|
inside 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.
This tool is a(n) __________.
outside caliper |
|
outside micrometer |
|
inside caliper |
|
vernier 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.
