What is a micrometer used for?
measuring length around corners |
|
transferring dimensions between objects |
|
ensuring that a surface is level |
|
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.
You're constructing a cabinet in your workshop and one of the cabinet doors is slightly too big. Which of the following tools would you use to make it fit?
chisel |
|
plane |
|
drill |
|
file |
In wooodworking, a plane is used to shave off a small amount of material to smooth a surface or make it fit properly. A jack plane is a general purpose plane that contains an adjustable depth blade set at an angle with a handle and knob to allow gripping when sliding the plane across wood.
This tool is a(n) __________.
outside caliper |
|
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.
Which of the following saws would you use if you're cutting wood along the grain?
hacksaw |
|
back saw |
|
crosscut saw |
|
ripsaw |
The ripsaw delivers maximum efficiency at cutting with or along the grain (ripping).
Screwdrivers are most broadly classified by their:
tip |
|
width |
|
torque |
|
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).
