What is a micrometer used for?
ensuring that a surface is level |
|
measuring length around corners |
|
transferring dimensions between objects |
|
measuring the diameter of cylindrical objects with high precision |
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.
Screwdrivers are most broadly classified by their:
torque |
|
width |
|
tip |
|
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).
When using a hacksaw, blades with __________ teeth are more appropriate for cutting thinner materials.
more |
|
thinner |
|
wider |
|
less |
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.
When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).
high |
|
odd |
|
even |
|
low |
Blades with more and smaller teeth (high TPI) cut harder metals more effectively while blades with fewer and larger teeth (low TPI) cut softer metals more effectively.
