- Hey! You seem a bit lost. Need some help with the lesson?
- Ok no problem. Meet me on the bleachers after school.
- …and that class is all you need to know about the micrometer! Any questions?
- Friday 4th February, 2022.Physics Class 101
- Man what is this teacher saying?
- Ok Great! I'll be there. Thanks a bunch
- Yes please. I don't understand this at all
- On the sleeve, there is a main scale, and on the thimble there is a rotating vernier scale.
- The micrometer screw gauge consists of eight parts: the frame, the anvil, the sleeve, the thimble lock, the screw, the spindle, the thimble, and the ratchet stop.
- A micrometer screw gauge is a device used to accurately measure the diameters and thicknesses of minuscule objects.
- THAT'S CORRECT!
- The range of a micrometer screw gauge is 0 - 25mm AND I know that the smallest division is 0.01mm
- The range of a micrometer screw gauge is-
- OH OH, I know this one!
-
- Next you adjust the knob and make sure that the object is held between the jaws firmly.
- Ok, now onto how to actually use it.
- If there isn't any, you place the object between the jaws which are moved by the thimbles.
- First you must close the jaws of the micrometer to confirm that there is no zero error.
- Each division is 0.01mm so therefore there are 0.46mm on the scale.
- There are long lines every millimeter and the short ones are every half millimeter.
- The thimble should be moved until three clicks are heard. The main scale has a linear scale reading on it.
- Make a note of the main scale reading. Now look at the rotating scale, that scale denotes 46 divisions.
- Oh shoot. I think the team is coming. Let's finish this at my house
- Make a note of the reading on the rotating scale. Add the readings on both scales and that will be your final reading.
- My lord this sounds complicated
