Which of the following would provide the most accurate measure of the diameter of a solid cylinder?
outside micrometer |
|
ruler |
|
tape measure |
|
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.
What is a micrometer used for?
transferring dimensions between objects |
|
measuring the diameter of cylindrical objects with high precision |
|
measuring length around corners |
|
ensuring that a surface is level |
