Which of the following is not an aspect of the mechanical advantage of pliers?
focus hand grip force |
|
amplify hand grip force |
|
change the direction of hand grip force |
|
provide precision for manipulating small objects |
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.
Which of the following statements about drill bits is not true?
drill bit size maxes out at ½" for metalworking |
|
drill bits are primarily right-handed |
|
drill bit size maxes out at ¼" for woodworking |
|
drill bits are primarily left-handed |
Drill bits remove material to create holes. They come in a variety of sizes, maxing out at ¼" for woodworking and ½" for metalworking. The majority of drill bits are right-handed which means they cut while rotating in a clockwise direction.
You need to loosen a bolt in a hard to reach location. Which of the following wrenches would best suit this task?
open-end |
|
box-end |
|
adjustable |
|
spanner |
Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.

wrench |
|
punch |
|
chisel |
