Given that the imaginary figure is 90°, what happens when it is rotated 45°?
You may refer to the metacentric diagrams.
However much you rotate it, things that are at 90° to each other will remain perpendicular.

I have to thank you at least for confirming that that method was used for durations of time, despite dozens of posters claiming they have never come across it in all their days.
As for the 1950's...
So not sure where the ' and " came from for hours and minutes...
...or alternatively minutes and seconds.
Both were considered OK.
You wouldn't really use this notation in homework or exams but OTOH you wouldn't lose marks if it was clear to the examiner what you meant.
When I stated 35" I assumed it was obvious what was meant but clearly not.
no intention of 'dumbing down' as it were, even if it doesn't conform with the US ways of doing things (actually making things more complicated than necessary IMV).
So to illustrate it to one poster who claimed to be baffled, I inadvertently wrote it as 0.35'
And why can't you type the words, "35 minutes" like a normal person?
The journey time from Visby is circa one hour and from Berga 40 minutes.
35' for feet is quite normal convention.
...it should have read 0'35" to make the point it was 35 minutes of an hour (because it was less than one hour it didn't need to be mentioned, in the same way you can put 6" for length without having to put 0' for feet if it was less than a foot).
Alas, it didn't go down well and caused more confusion and chaos on the level of world war three breaking out!
Hopefully, he and others now appreciate that 35" did not refer to depth of water...
...which would be written 2'11" anyway...
Feet and inches primes operate on on a base-12 notation, just as geolocations and time assumes a base-60 one. Therefore thirty-five inches translates as 2'11". It is technically incorrect for the second primes to go above 11.
It would not credibly sink in 35 seconds. Context is all.
So, when you see 35" and the context is duration of time, then do assume they refer to minutes as a unit of time. Anything over 59" would then convert to 1' x". Where x = time in minutes.
But no-one has confirmed that " was used for minutes. That's your real error here, insisting that ' can be a valid way of designating hours and " can be a valid way of designating minutes.
It isn't, and if you were taught that way at school, then you were taught wrong, despite your snooty Oxbridge educated mortarboard and gown wearing teachers.
Brilliant
Using &t$ for minutes of time duration was conventional for me. I have no recollection of having been 'taught' it but we all did it.
In other words you received a second class education in a snooty atmosphere run by pretentious prats who never pulled you up on your non-standard use of primes.
You could have simply said - "Well, we used it that way at school, and nobody ever told us it was wrong, but if it is then I apologise and will stop using it that way in future seeing as it causes confusion."
However much you rotate it, things that are at 90° to each other will remain perpendicular.
Both can be true. I merely noted that it was not a notation that someone trained in the sciences would use. You have claimed "five years" of physics education (i.e., O-levels, in which the primes notation for time was not taught or tested) and, at other times, you have claimed to be a scientist. I pointed out your use of nonstandard notation merely as evidence that neither of those claims was likely true.
I can find no evidence of the use of primes notation for time after about 1950. I believe multiple people when they say it wasn't taught to them as part of their curriculum, which would have been roughly concurrent with yours. It's therefore quite reasonable to believe that people living today have not encountered that notation, disused and untaught for 70 years.
Irrelevant rambling ignored.
If you wish to claim this was a common or accepted usage, you had better discover where it came from and substantiate it for the critics you're accusing of ignorance for not knowing it. Otherwise withdraw the claim.
This is the only acceptable usage according to the relevant standard. I have explained why. That standard has been superseded in recent decades to substitute nominal units instead of primes.
If this is true then it merely confirms that you were poorly educated. Nevertheless you claimed "we all" used that muddled notation. Can you produce any evidence of anyone but yourself using it at any time?
This is not your only abuse of primes notation. As others pointed out, you used ″ to indicate degrees. In a post last year, you quoted from Mr Justice Sheen's report on the loss of the Herald of Free Enterprise. Sheen correctly wrote (sec. 9.3) that the ship had rolled to 90º. But you transcribed it as 90″. Did your quaint school also allow ″ to represent any arbitrary unit of angle without context, rhyme, or reason?
Granted not everyone wants to take the time to discover how to put the º symbol in a post. But your solution wasn't to write out "degrees," which would have been acceptable. Instead, your solution was to further abuse primes notation and proffer a symbol that means something in angles, but entirely the wrong thing.
It's easier to believe you just don't know how primes notation works than it is to believe you were educated this way.
In my class you would have lost points, first for using a nonstandard notation for time, and second for using it incorrectly. You would not have passed any class I taught, nor any exam that I administered. The correct use of units and symbols is considered essential in any technical context. It is never overlooked on the whim of an examiner.
If you knew it wasn't proper to use ″ for minutes of time on homework or exams, why did you think anyone here would immediately know what it was supposed to mean? It's either a widely-enough accepted standard that one other person would demonstrably have heard of ″ as minutes of time, or used ″ to mean minutes of time, or you're wrong.
Nonsense. Under the (wrong) premise that ″ can indicate either minutes or seconds, you provided no information to tell the reader which you intended. You admit that your vernacular usage risks ambiguity. Why would you assume your meaning was obvious? Now you're claiming it's a minority usage, but not long ago you insisted that it would be "[h]ard to see how" anyone could misinterpret you. And you further insisted that you had
This suggests you believed your notation was correct and common outside the U.S., and what you styled to be the U.S. convention was an unwelcome complication.
No, you're just digging yourself in deeper.
No, it wasn't inadvertent. You first wrote 35″ wrongly believing that meant minutes of time. You repeated the error, even after having been corrected. Not until several days later did you start using the correct primes notation, 35′, for minutes, but without acknowledging any of the efforts to correct you. Perhaps you believed if you unobtrusively corrected yourself, your previous error would be forgotten.
It's worth noting that you were asked
There are plenty of examples of you using more conventional notation, e.g. :—
You use primes notation only for the time it took MS Estonia to sink, at first incorrectly and then correctly. You could have avoided all ambiguity--for which you were being roundly roasted--by writing out 35 minutes or 35 min--both well-established, widely-used standard notations. Were you trying to emphasize the correct use of primes notation, for that value only, in the hope it would supplant your mistake?
Days later you wrote 0.35′. (Someone misquoted you as 0.35″ and others including myself perpetuated it.) When this latest gaffe was pointed out, and an explanation demanded, your answer was
Back then your explanation was certainly not
Now you're claiming 0.35' was a typo, and what you really meant to write was 0′ 35″, which you further claim would have made the intended units unambiguous. But it took you days to arrive at this new explanation, that you had simply mistyped both the decimal and the double-prime. Correcting the typo somehow didn't occur to you days ago when you were being asked to clarify what 0.35' meant. You repeated the typo instead of correcting it. So I believe "It was a typo" is just your daily change-of-story in the ongoing pretext to incorporate others' corrections into an, "I really knew it all along," ploy.
The confusion and chaos is entirely the result of you changing your story on a daily basis, pontificating about things you know nothing about, and maintaining steadfastly that it's others' fault for being unable to decipher your ignorant gobbledygook.
We belabor it because it is evidence of the level of dishonesty, ignorance, and bluster you have employed at this forum. That in turn speaks to whether you are technically competent and morally qualified to pass judgment on the expert work of others who investigated the sinking of MS Estonia.
Nobody seriously did. They're just mocking you for the absurdity engendered by your compound errors, and amplified by your ongoing ham-fisted lies. Without context, the most natural interpretation of 35″ is thirty-five inches, since it's the most common primes notation still in use. They're mocking you for being incorrect and unclear.
No. It's perfectly acceptable to leave such extents in inches. If I order a six-panel door for a standard American house, its dimensions will be given in the catalog as 32″ × 80″. Despite yet another of your ignorant claims,there is no requirement to normalize any quantity in primes notation. You conceded as much when you wrote 6′ 2 ⅛″ instead of 2 yd 0′ 2-⅛″.
In American architecture, however, the AIA and UBC require dimensions 12 in or longer to be expressed on drawings in feet and inches. But this is a narrow requirement that doesn't even apply to all aspects of the American building trades or other areas of commerce. In contrast, the ASME standard is that when inches are used as the primary unit, only (decimal) inches are used even if a dimension amounts to more than a foot. We buy a 32″ door from the lumber yard, which goes into a hole labeled 2′ 8-¼″ on the floor plan. And then we can stand in that doorway and watch a Boeing 707 fly overhead at 500 ft/s whose plans show it to have an inside fuselage diameter of 139.3 in.
No. Correct use of the proper units and notation is paramount, as the various qualifying and licensing exams go to great lengths (pun intended) to instill. No inference of context properly redefines standard symbols and units. No, it's not credible to imagine that a large ship sank in 35 seconds. But if you writeThe ship sank in 35″.The most natural modern reading of it is, "The ship sank in thirty-five inches," as absurd also as that would be.
You wrongly claimedBut you did not establish that the context was time. Your statements were all of the form, "The ship sank in 35″," full stop. Besides, you chose an outmoded method of notating time, and used it incorrectly. It's not your critics' fault that they didn't unravel your tapestry of omissions and errors to properly divine what you might have meant. On the contrary, your ineptitude illustrates exactly why the world insists upon precise and immutable notation.
You can make this stop. Just admit you were wrong to write 35″ intending to say thirty-five minutes. Just concede that wrongness is a property that can attach to your beliefs and claims.
Or just stop concocting ever more dubious piles of codswallop to pretend you know what you're talking about.
excerpt Sheen documentThe HERALD came to rest on a heading of 136" with her starboard side above the surface. Water rapidly filled the ship below the surface level with the result that not less than 150 passengers and 38 members of the crew lost their lives. Many others were injured, The position in which the HERALD came to rest was less than 7 cables from the harbour entrance and was latitude 22' 28.5" North, longitude 3" 11' 26" East.
You are the one who introduced thered herringperpendicular issue. That is your strawman.
This is like debating with someone who claims Paris is not the capital of France. In fact, the arguer vehemently affirms, he has never heard of Paris and therefore it does not exist! The astonishing thing about arguing against something that is an established fact is that someone should wear their ignorance of Paris as a crown.
However, how desperate do you need to be to go through a quoted post from a document looking for a typographical error.
So now you are going to be claiming for the next umpty-nine posts that I don't know how to notate latitude and longitude.
Perhaps it might be better to relax instead?
I am disappointed that you haven't apologised to me for falsely accusing me of all kinds of wrongdoing.
That is the measure of a man's mettle.

As I said, when I copied and pasted from the Sheen pdf. Microsoft Word transposed the degree sign to inverted commas. Had I noticed or thought it important I would have corrected it, as it is hardly difficult.

I expect it was a 'text recognition' translation making for poor copy.

As Shirley Conran once said, 'Life is too short to stuff a mushroom'.
So now you are going to be claiming for the next umpty-nine posts that I don't know how to notate latitude and longitude.

Oh mannnnnn.
Look, I'll try to make it as simple as possible to understand.
Imagine you are the captain of a ship. You are standing on the bridge, right in the centre of the bridge, looking straight ahead along the centre line of the ship.
OK with the concept so far?
Now, picture an imaginary line which runs from your eyes, through the tip of the bow of your ship, and out towards the horizon.
Still OK?
Anything to the left of that line - even by 1 arcsecond - is port. And anything to the right of that line - even by 1 arcsecond - is starboard.
What we could use right now is someone who is well versed in something like accountancy?
For whom the accurate and unambigious use of numbers would be second nature?
Yeah.....ummmm......what?
These are not typos. They are errors in usage accompanied by increasingly fabricated claims that they are nevertheless still somehow correct. You will not admit even the slightest error on your part, which disqualifies you from credibly reviewing the efforts of your betters.
Straw man. My principal claim is that you insist upon incorrect notation for time durations, and that you have concocted an increasingly incredible story for why you think it's nevertheless correct. I have provided ample evidence to support my claim, which you do not address.
No, I don't think I will. I think I'll continue holding your feet to the fire until you either admit you made a mistake or provide evidence to support your claim.
No, you aren't some sort of victim here. I was good enough to present a fully-developed line of reasoning complete with documentation. You ignored the bulk of it, so you have no business complaining of anyone of making false accusations.
Among many other things, I don't consider you qualified to determine a man's mettle.
I'm correct. I know I'm correct because the things of which I speak are part of my licensed profession, and part of what I taught in college.
You can make this stop. Either provide the evidence that your vernacular usage is something that others besides you used and recognized, or just say, "I made a mistake." Whining that you're the victim of ill treatment and begging to be let off the hook will only steel my resolve to hold you accountable.

Stop trying to change the subject and context. We were talking about a physical ship and a physical side of the vessel. The topic at hand was at which point would water came over the physical starboard side of the vessel when it listed at 45° in context of the sea, and at which point it is likely to capsize.
You claim to trump me because you are a licensed professional.
I am a chartered professional and not given to dishonesty of any form.
So you have falsely accused me of inventing a prime system...
...and of inventing an FX acronym.
You refuse to take it back even though you admit in a rare flash of frankness that you have heard of primes to denote time duration after all.
