@@streetpeter3210 Yep, weakened beams no longer holding up the weight of the top floors was always the official explanation, not completely melted beams.
normal steel glows at about 800 C, and kerosene burns with over 900 C. so while it cant melt it, it obviously can reduce its rigidity by half at that temperature. significant if it needs to carry several levels of a skyscraper. ^_^
@@HydraulicPressChannel hello and greetings from St.Louis Missouri! I noticed at about 5:39 you said the number 3 (three) but it didn't sound like how we say three from where I live. Was that you supplementing the number with your original language? or was it just an extremely thick accent that I couldn't catch? LOL Great video all the same!
@Freedom Fighter Blacksmithing has been a very real thing for humanity for over 2500 years, they heat up iron and steel to soften it in order to shape it, even at lower temperatures than what is seen in a jet fuel fire. To try to claim that fire being a major factor in the collapse of any steel frame building, let alone two as tall as the WTC is like trying to deny that we have ever used blacksmithing. Oh, and your line about "all buildings in history never collapsed by fire weakening it" is bull hockey, as I have seen a fire that took up a quarter of a steel frame/side warehouse collapse it, right here on RUclips.
Actual break strength of trailer tow balls would be a neat one that occurred to me the other day, how far over the listed rating do you have to go for failure?
Breaking a new (well made) one would require some excess forces. Breaking a well-made well-worn one, who might say what the aggregate impacts might compound to its suitability of use, especially heat, corrosion, unseen stress fractures. It would be interesting to see.
@@Wingnut_Stickman That's a good point. Aggregate impacts is the top question about these too. On a side note I have noticed a lot of shiny Aluminum Drop hitch draw bars on fancy trucks. Peterbilt tried aluminum frames in the 70s and immediately stopped production even with doubled frame rails.
I think it is safe to assume that trailer hitches, trailer hitch Balls, ball mounts, axles, hubs, wheels are VERY conservatively labeled with "maximum" capacities. I would like, however, to see different strength tests of welded pieces of metal and compare the strength of 6010, 6011, 6013, and 7018 welding rods.
I would be curious to see how higher-end tubing, like used in bicycles and race cars, holds up. Round Carbon Fiber, 4130 Chomemoly, and both 6061 and 7005 series T6 Aluminum. Probably find a common diameter for all of them, like on the downtube of a bicycle or roll bar of a race car. That would be cool to see what holds up best.
Steel bicycle tubes have thick ends and a thin center section for weight, so it would be good to do tests at the ends and center to see the difference.
@@kingedwin Only double butted bicycle tubes do that. Not all bicycles use double butted tubing, although most higher end ones use double or triple.butted air hardening chromoly steel.
Your celebration at being almost exactly correct with the 10,000 was wonderful, I imagined you doing a little dance of sorts as well. It made me smile.
The steel supporting tubes changed distance through the session changing the stregth of the tested tubes significantly. Next time, try I beams or H beams, they should have many times the strength of the tubes.
Now that we all know how much weaker steel is when heated up, the obvious next question would be, does it get stronger when being cooled down? At least before it gets so cold that it cracks instead of deforming
The answer is no. Unless you get a specialized steel that it stress tested at low temperatures, it will always be weaker when it's cold. Instead of slowly deforming like it does at room temperature, it would most likely resist deforming a bit longer, but ultimately should fail sooner
There’s also varying strength levels in steel depending on the carbon content, the heat treating processes, trace elements and other factors. Got a few friends who are blacksmiths
Correct. Steel is the broad term for the alloy. The recipes for steel and the accompanying recipes for heat treatment are... numerous. You'll find there are some very popular steels but even now metallurgy and engineering are trying to find the best steel for everything from knives to cars and more. Most blacksmiths don't care to know much about steel beyond simple oil and water hardening steel.
@Hydraulic Press Channel at 7:35 if you want to heat that pipe a little more efficiently, it needs to be insulated from the blocks. They are acting as a heatsink. A couple of heatproof pads would do it. If smoke is acceptable, a little bit of wood under the ends would also work. 🔥 💚🐇🐴💚
They are not "Pipes", They are "Box Beams", but I guess you could use them to move fluid through if you had to. Also I do not like how you stack those steel blocks for testing, they will fly off, like it did in one of the last tests.
Nice! It would indeed be interesting to see a version, where that steel pipe is really hot (at least 1000 C - which is like bright orange hot) and also more evenly heated (now it was just the middle top part, that was red hot) :)
it wouldn't be that interesting, it would act like lead. You could bend it with your hands, probably less than 100kg of downward force would be enough.
>How Strong are STEEL and ALUMINIUM tubes? Hydraulic Press test! Fixed the title for you. Oh wait, he might have omitted it as he didn't want further arguments in comments on the spelling. Carry on then
Looking at you crush the square pipe I wondered if it would make any difference in strength if you set the pipe on the corner so you were crushing the opposite corner. So instead of crushing square it is like a diamond shape. The corner should be stronger than the flat I think.
Can you xray materials or use electron microscope on materials at different pressures to see what is happening to the structure under specific pressures. Before breaking of course to not damage equipment. I would check at standard atmospheric room pressure then add some pressure take another snapshot and add some more pressure but don't go all the way until breaking. You could just check multiple pieces of the same materials like metals and glass first to get a good general idea on what pressure to not exceed. I believe this will give us a good idea about what the structure is doing at the very tiny scale before anything breaks. I know what we can't do is see how atoms are spreading apart or being squeeze something i would like even more.
Thank you for that test: i had doubts if 45x25x2mm aluminium beams would be strong enough to hold 3 2x1m solar panels on the roof of my camper, it looks like i will be fine. It would be nice to test the strength of a bolted alu-steel connection with M8 nuts and bolts, with varying washer sizes (optional), and in shearing or traction (most interesting) and see what fails first. Optionally add a mix of loose bolt, properly torqued, and over-torqued. Then add a dent in the aluminium beam and check if under extreme stress that dent could become the start of a bigger crack.
If you can get a proper forge, you can get steel rebar red hot and it can be bent in circles with just a pair of pliers. It doesn't melt, but it takes substantially less force to bend than even one level's worth of pressure, never mind a whole goddamn skyscraper!
Just my opinion, maybe test 3 identical pieces of square tube, one as bought, one heated, and one heated and allowed to cool. Without getting super technical, heating and allowing to cool will change the strength.
For once I actually watched the advert and may buy it because I LOVE documentaries but spend hours trying to find good ones on all the other subscription services.
I would like to see the experiment where you are trying to compress the water since it is so hard to compress and it does compress only 3% under a lot of force...
NOW here was the steel made?? Here in Oz there is a good deal of difference from local to imported. And the imported is not so nice to weld either. That 50x75 is what I build car trailers from. Cheap stuff cracks good stuff works fine.
normal steel glows at about 800 C, and kerosene burns with over 900 C. so while it cant melt it, it obviously can reduce its rigidity by half at that temperature. significant if it needs to carry several levels of a skyscraper. ^_^
I'm wondering if these tests are flawed in that the ends of the pipe are not held rigidly. I can't help but wonder if this would change the flex characteristics of the pipe and, ultimately, the test result.

@@ommsterlitz1805 you might want to check that pointlessly predictable comment with the Brits - they're thinking about switching to imperial, too.
50% drop in strength!! That is why they put fireproofing on the structural steel in buildings. Great video!
I ate fire proofing for lunch this week
That's why jet fuel can't burn steel beams /s🤣

“Jet fuel doesn’t melt steel beams!”
Yes, but it does make it structurally much weaker and prone to collapse.
People who make this comment should try a 100% nitrogen atmosphere. But you can breathe it in!
You know, it's kind of funny how we've been using heat on iron/steel for over 2500 years to make stuff, yet somehow people don't believe in it now.
@Freedom Fighter can I know where you found the database info for every structure ever to collapse in the world ever?

Actual break strength of trailer tow balls would be a neat one that occurred to me the other day, how far over the listed rating do you have to go for failure?
if they're quality made, 250%. If they're crap, 20%-50%
Thats a great Idea. I would also like to see Trailer Springs , Then Hubs , then Spindals

They probibly would need a better loading method to not breake the tubes
Steel bicycle tubes have thick ends and a thin center section for weight, so it would be good to do tests at the ends and center to see the difference.
They're all different sizes and wall thicknesses, even within one tube as noted by Edwin. Would be a cool test if done comprehensively though.
He needs to do the test properly with longer lengths or more spread pressure area... it's just causing the top of the extrusions/box to fail.
@@kingedwin Only double butted bicycle tubes do that. Not all bicycles use double butted tubing, although most higher end ones use double or triple.butted air hardening chromoly steel.
Your celebration at being almost exactly correct with the 10,000 was wonderful, I imagined you doing a little dance of sorts as well. It made me smile.
Would be cool to see a dry ice cooled versus room temperature versus hot metal
"Da da daaa da de do daaaa Preti ga dam guud!"
That song will be in my head all day.
You need to make a shirt with "We have to deal with it" and a clay figure picture because that would be awesome.
Along with it saying "It is extremely dangerous and may attack at anytime."
@@Steveman27 yes, that would be a necessity.
The steel supporting tubes changed distance through the session changing the stregth of the tested tubes significantly.
Next time, try I beams or H beams, they should have many times the strength of the tubes.
So Jet Fuel doesn't need to melt Steel Beams to weaken them enough?! oO
Conspiracy theorists beware.
Damn, you beat me to it. I will add that fires get hotter when they get more air, you know like wind speeds that can make the smoke go sideways.
Now that we all know how much weaker steel is when heated up, the obvious next question would be, does it get stronger when being cooled down? At least before it gets so cold that it cracks instead of deforming
The answer is no. Unless you get a specialized steel that it stress tested at low temperatures, it will always be weaker when it's cold.
Instead of slowly deforming like it does at room temperature, it would most likely resist deforming a bit longer, but ultimately should fail sooner
At least some steel actually does, EVEN if you let it heat up to room temperature again.

The smallest square aluminum tubing was definitely impressive. I didn't think it would take that much force.
Same, i vastly underestimated aluminum.
This is why a lot of bridges are so-called box girder bridges, because they can take a great deal of loading without failure.

Today on the hydraulic press channel we will be testing whether or not jet fuel can melt steel beams
That's a really big couch you have there.

Can you make another test but with concrete mix with gravel inside the tubing so we can compare the strength... Thanks
Engineering classes need to add these videos as homework. You get really good visuals of how different materials hold up to pressure.
I have a great plan for the beyond the press channel, can you pull on hydraulic hoses and see how much weight they can take ?
you should do an FEA analasys of tubes or beams like this, then you and anni can guess if it will be higher or lower or the same as the simulation.
Thank you for that test: i had doubts if 45x25x2mm aluminium beams would be strong enough to hold 3 2x1m solar panels on the roof of my camper, it looks like i will be fine.

How about using the same type of tubes as this video, only standing on end, to see how much force is needed to make them bend/break?
I think they have done that. I remember it making some really neat sculpture shapes.
Can you see if with enough heat and pressure if you can completely shear off a steel reinforcement? Without it bending, can you achieve a 45° shear?
If you can get a proper forge, you can get steel rebar red hot and it can be bent in circles with just a pair of pliers. It doesn't melt, but it takes substantially less force to bend than even one level's worth of pressure, never mind a whole goddamn skyscraper!

Test concrete compression and tension. Beams as well as hardness
I would like to see the experiment where you are trying to compress the water since it is so hard to compress and it does compress only 3% under a lot of force...
Doesn't matter how thick you make it, the material itself has a yield strength too :P
How about heating the steel slightly to about 350-400* F ?
Literature claims steel( even high- carbon) will gain strength significantly at that temp.
Please please PLEASE make a compilation of Extra Connect video.
...so we have to deal with it" in a Finnish accent, is my favorite phrase.
Do we want to see it? You know we do!!!
Put the pipe into a larger pipe and point the burner along the length of it. Might be enough to heat it evenly.

Saw a grenade in what looks like a hydraulic press in a movie. When can we see yours? 😂
♫ da da da-da doo-doo-doo-doo pretty god damn gooood! ♫

What about this video but with other extreme end? Super cold steel pipe vs normal
Your accent was my fav in this channell
I'm wondering if these tests are flawed in that the ends of the pipe are not held rigidly. I can't help but wonder if this would change the flex characteristics of the pipe and, ultimately, the test result.

Red Hot Pipe Vs Hydraulic Press
Totally Tubular bro. Check Nathan's suggestion and replies.

It would be very interesting to do this experiment but with temperature factor. Like, is the steel very more weak if its at only 500° C ?
Indeed, do not troll the blocks away... 😸
White Hot steel vs Hydraulic Press is a good idea!
These wrecked tangles are surprisingly strong! 😁😉
Have you done I-beams yet? Try making the material like -10 C to see if it gets stronger. Too cold and the metal becomes too brittle.

You need a thermal camera, to show how bending affect temetarute of test subject.
Looking at the title there's only one thought that comes to mind
"Jet fuel can't melt steel beams"
Consider reverberatory furnaces.
Pls do steel scale vs hidroulic press
I just built the bed of my truck out of 3x2=0.125, got to say, I still feel good about it.
