It is definitely a conceptual mistake, as you don't even know when it is appropriate to use high strength steel versus other grades.
HY-180 steel, for example, is still just steel. It's not reinforced with anything; it's just stronger than mild steel. You can reinforce a steel
structure by adding members, say stiffeners or stringers . But that would be a structural argument, not a materials argument (i.e., not one you'd study with metallurgy). That's not the kind of reinforcement we're interested in. Here it appears the goal is to exaggerate the strength of the steel in order to suggest that it would take causes beyond those ordinarily encountered by a ship throughout its life to produce the effects noted in a metallurgical examination.
The problem ultimately is that Vixen typically doesn't know what she's talking about, but still insists that we take her seriously. She tries to dismiss calling her on mistakes in her claims as "heckling" or "bullying," thereby shaming people away from criticizing them. According to the presumed rationale above, it would be appropriate to narrow down what is meant by "reinforced steel." Ship shell plating, for example, is typically made from mild steel in order to preserve ductility, which is lost as steel increases in hardness. You want the plating to bend when stressed—ductile behavior—not fracture and thereby admit water. But conceding that the steel in question is not particularly tough (for steel) allows that the injury observed in it does not require an extraordinary cause and thus does not compel us to reach for conspiratorial hypotheses to explain it.
The doubling-down is especially egregious, and indicates bad-faith argumentation. The first answer was along the lines, "Let me go look up what 'reinforced steel' means." When that didn't satisfy, the next claim was along the lines, "It was obviously a misquotation." And when asked what source was being quoted, the answer transmogrifies into, "It was a typo made in a momentary state of fatigue." Three completely different answers, none of which requires her to admit the likelihood that she just made up "reinforced steel" to sound knowledgeable.
We could certainly accept, "It was a typo and I didn't mean it," and allow that maybe Vixen really does know how steel works (apart from welding), except that this isn't the first time (or even the third time) she's used this phrase :—
No it is not easy enough, nor could it be done quickly and why just London? Nothing to stop such an attack taking place somewhere like say Warrington.
It's the copycat aspect. Perhaps all major city centres along popular thoroughfares should have simple concrete posts (or reinforced steel)constructed say every six feet along the pavement edge (as we see on street corners), so people can still cross, but cars couldn't mount the pavement far.
I've lost count the number of times I've strolled across London Bridge. It's all too close to home.
There’s a thread in CT about
this.
Wish I'd known about that thread! Seems the Swedish and Estonian authorities are no longer treating it as conspiracy theory.
It is all very well saying the four metre long gap happened when the stern hit the seabed. However, it is not just a gap, there is actually a 1.2m hole in the middle of it. As ships are designed to be bouyant - the Estonia took a total of ninety minutes to sink - so even if it did sink to the bottom once the bow was 45° it seems unlikely to me that a 'rock caused the hole in the hull' and the split in the thick...
Welding works by melting the steel.
Look. Water boils at 100°C. If you have a gas stove, then the flame you are using is anything up to 600°C in intensity. Yet it takes at least 4 - 6 minutes to boil 1 pint of water.
How long do you have to point your arc welding cutter at a piece of thick reinforced steel to get it to melt? It certainly doesn't happen instantly.
Well, dearie me!
Weird beliefs of the general public
• When a vessel capsizes, it floats around on its side.
• A strong wave can cause a reinforced steel bow visor to just simply fall off.
• The bow visor falling off meant that the cast iron door of the car deck also opened.
• This opening was enough to cause instant flooding of the car deck and the ship to sink within thirty-five minutes.
• Notwithstanding the car deck ramp-style door opening to let in a huge torrent of water, it then shut all by itself, sufficiently enough to enable two Estonian athletes to climb down...
@BlueMoutain: re your comments elsewhere:
- It was confirmed by a naval official at the official investigation that the EPIRBS were automatic EPIRBS.
- It was confirmed by a Norwegian professor of Metallurgy that the type of deformation seen in the bow were compatible with an explosives reaction and she did say this type of deformation in reinforced steel is only reproducible in a laboratory and at temperatures >800°C. If you want to mock an expert, that reflects on you, not me.
- Underwater images did indeed show submersible track marks on the Baltic Sea bed.
(etc.)
...nor the first time she's been corrected on her misuse.
How is that relevant? Is that all you can do, search around desperately for typos or a sentence taken out of context?
At least I knew what deformations were.
How is it taken out of context?
What typo?
You originally claimed the hull was 'reinforced steel'
When you were shown that it wasn't 'reinforced' and that the thickness varies depending on location you admitted you knew nothing about it.
It's a mistake she has made so often in the face of correction that not only is it proper to characterize it as a conceptual error, it's proper to characterize it at this point as deliberate misrepresentation.
Now matter how much handwaving is offered about chartered accountancy or psychology, disclaiming expertise in metallurgy followed by copious examples of not understanding how steel works and covering up for it in ever-changing face-saving excuses has consequences for an argument that purports to interpret the metallurgical findings in a way that requires explosives to produce the reported effects.
