A, B, C or D

Sure as eggs that piece of junk doesn't meet ISO 17025. [biggrin]

Yep. A is the answer.

Even the apprentice worked this out

I’m not assuming anything when the lower graduations actually line up with the upper at random intervals [emoji41]

I wouldn’t have used this pos though from the moment I picked it up.

The correct answer is likely to be 26.98mm based on the quality of those graduations [emoji41]

Yep, it should read 6, 12, 18 and 24.

Hello All,

According to Bob Welds and his dog, "Sparky" - who is "pointer" from Weldnotes.com - the answer would be A. This is because the horizontal measurement is 13.50 MM and the thimble vertical measurement is 0.13 of a MM. This equals 13.63 MM

My apologies for finding an animated video of a bloke and his dog explaining micrometer reading. The inaccuracy of the half a MM marking on the bottom scale of first post's diagram does not aid easy interpretation. I fixed the bottom horizontal scale up a bit so it appears more to scale. See below.

We are having a thunderstorm here. Snowy my 110 Defender that I am working on is parked outside without any cover. I am at a little bit of a loose end at the moment. Yep - it's still raining...

Kind regards
Lionel

As stated, we are all assuming it’s a micrometer.
And from my experience with micrometers, the intervals at the bottom would be the .5mm increments.
From my experience, diagrams are not always accurate or too scale.

I don’t know how the answer could be 26.98mm, maybe I should have stayed a couple more years at school [emoji12]

It’s a rubbish micrometer,belongs in the nearest bin.

But if you ignore the lower graduations,and presume it zeros on each of the top graduations,it’s D.

Because based on the poor graduations indicated; whilst it reads ~13 it’s likely out by tolerance of a cricket pitch. [emoji41]

Hence my comment [emoji56]



When I come across drawings of such inaccuracies I don’t answer, I escalate.
If that was presented to me, I’d blatantly reject it.

Trick question - answer is:

E/ 11.6543 cubits

A
