Thread: A, B, C or D

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

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

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

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.

Hence my comment



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:
