The 0.5mm measurements are out of alignment, especially around 5mm.

The level of accuracy is .0083mm also instead of the normal 0.01mm.

The answer could be better found with a wet wooden ruler because no machinst would use that micrometer.

Is this a question from an exam…. It reminds me of so many high school / uni questions where I couldn’t help but write an answer to a multi choice ….

I think in this instance a younger less chilled out me would have written

“It pains me give you the answer A as your question is a complete failure with respect to accuracy and repeatability which should be hallmarks of the science of physical measurement”

I would happily hedge to win or loss knowing that

I was “right and justified”


Now I’m old and jaded id just tick a and move on

There have been a number of pictures of that micrometer put up, they all appear to have been edited to be slightly different to each other.

Image 1. The 0.5mm marks on the barrel are incorrectly spaced, there are 5 divisions between major units on the thimble.
Image 2. The 0.5mm marks on the barrel are correctly spaced, there are 5 divisions between major units on the thimble.
Image 3. The 0.5mm marks on the barrel are correctly spaced, there are 4 divisions between the major units on the thimble

We are all still assuming it’s a micrometer

As RoverRescue has asked is it an exam question ???
As with most exam questions they are vague and the correct answer will be further on in the exam

Good grief !!!!
Is this not being over analysed to death, I will be really happy when we are able to get out there in the bush or the outback. WHEREVER.....

Whatever it is, it was made in India or China.
