you're right

underrated comment

It's illegal to destroy money. I have turned it into the police.

@@tankl.jackson3481 yea sure the police are gonna care. Ever been to disneyland? You put a coin in and it stamps it with a design? The police dont give a shit.

With enough force and potential energy, anything is possible!

imagine getting shot by a fucking book lol

It's actually pretty obvious that's what would happen when you understand the forces at play It's the same principle behind a volcanic eruption: lots of pressure builds up in one place, eventually it's enough to overpower the forces kipping it at bay (the surface rock for the volcano, the tensile strength for the book) witch results results in all that pressure begins released BOOM

I was shocked at first too, then I remembered there was such a thing as dust explosions, where enough combustible particles collect in a tight area can explode. And that's without any kind of external pressure like using a hydraulic press.

@@Alustar22 that’s very different, it’s an incredibly rapid burn.

That's called tension, Paper surprisingly has a high tension resistance, If you simply pull a piece of paper on opposite ends it will not tear, or will give a very hard snap if pulled hard enough, Because the press is pushing down on the paper, it wants to slide out from under the press but is evening out the energy in all directions at once and eventually, well, you can see what happens

Imagine the same situation occurring on a block of wood,since that’s effectively what a compressed book is. That paper didn’t shatter, it splintered.

hecking americans man.... just use 0.0025mm or 0.001mm or so, doing any type of machining or engineering work in imperial (or metric that has to be converted to inches) is just mental. Way too many issues like differing international standards, eventual errors in the conversion or just confusion (looking at you 25 million dollar lost sattelite or what it was that went down because of mixed use of imperial and metric)

​@@ToBeIsWasWere The satellite went down because of _mixed_ use. Not one particular system being "mental". It's also easy for the same mistake to happen within a system as well (Reporting mm instead of cm).

@@ToBeIsWasWere Just seen your reply. I only referenced metric for those that don't easily think in inches. I can easily work in either, and know well that mixing the two doesn't work well. Many customers will try to do so, because a lot of college trained engineers are stupid, but we send those blueprints back to be corrected, or we don't take the job. Also, while I'm am an American, you can take that attitude and stuff it in your sauerkraut. Been around the world while in the military and for my profession. I can tell you for free that stupid is everywhere and knows no country borders.

@@ryimscaith1593 Also as a machinist, I easily work in both, but never at the same time. Mixing them is asking for disaster, especially with for instance the NC machine I ran frequently, to go between you had to toggle it manually in the controller, and then load another program programmed for that section, then toggle back, too much room for an error, loading the wrong program, forgetting to load the other, or forgetting to change it to metric control at the stop, all of these reasons were why we would not do it. Also I did a LOT of manual machining, why not do it in metric? because the machine was made in imperial, and with no DRO, going on indicators and the scales on the machine, if it's made in imperial, I work imperial only on those machines. Tobias does have a point in conversion errors, however the shops I worked in never accepted a print that didn't match what the machine was set up to do, and say if they wanted a part off a manual machine and the print was metric, we sent the customer the print back, THEY can convert it, then as long as we make it to the print, it's not my problem if they converted it incorrectly. Machinist 101, make it like the drawing, so when they complain, you made exactly what they asked for, if it wasn't what they wanted that is a them problem, and they are still going to be paying the agreed price.

@@npip99 mm instead of cm I've never seen happening, one is 10 times bigger than the other

@John Alpha I used to do that too, but never managed to find them afterwards. They always seemed to get sent flying off, that or I was just not looking hard enough. Had the attention span of a gnat back then.

those drill was real le miserable quality - but nice in koala :-D

@@jimboSleeeeiiice I thought so too but it's not molten metal. There's a hole in the top of the hammer and you can see. Plus the tiny pieces left on the base would have cooled and not still been red. It's whatever was helping the handle stay connected to the head of the hammer.

The different failure modes! Stressed fiber (paper), Ductile (most metals), compressive failure of ceramic/rock.

@John Alpha Not stacked, but placed here and there. Rough wheels tend to pick them up for a few revolutions (3 to 20 feet)

All the tens of thousands of kg on stuff under one kg

This high speed camera isnt fast enough.

More interestingly, how this force is converted to elastic energy, and how the elastic energy is instantly converted to kinetic energy and to heat upon rupture.

a paper can cut you very well if you didn't know...

This is a great idea

I am simply amazed by how deeply satisfying this is!

"This is like, educational!" too cute.

It really is educational. Imagine paying about 1 dollar to keep your vision.

It's kind of amazing that the safety glasses were only _scratched_ after taking a chunk of a drill bit moving at an appreciable fraction of the speed of sound

You should see what happens with radioactive materials 😲

Yes

That's how stars work.

@@kibe2134 pretty much exactly this.

@@kibe2134 Extreme density is something I really struggle to understand and your comment has clarified a number of questions bouncing around my head. Thanks!

Under those conditions, the answer is yes and no. Elastic properties of the material play a big part.

Smashburgers

Haaaa

Mostly garbage compaction

A machine like this would be used in a manufacturing process where parts are quite literally press fit together when the matching pieces are machined in tight tolerance of each other within .001 of a inch or tighter. Think like bearing housings and stuff like that.

To kill the terminator

You should use something other than post it notes in your mine. Lol

@@HubertofLiege smh imagine using post it notes to support a cave. Cardboard seems like such a better alternative

E=MC²

@@AL-SH Wrong equation. You’re looking for F=ma. Force equals Mass times Acceleration. The force the press exerts onto the target is equal to its mass (heavy) times its acceleration (considerable). The targets deform until they can’t and then start absorbing that energy until they *suddenly* can’t.

nuclear reaction paper 🤯

Paper was crazy, how bout that knife though!!😮

The amount released is the same as the amount you put in. In this case, 70 tons of force.

Not guud 🤭 I like when he says this.

sounds like marco repairs coffee time for talk english

Where is he from?

@@hectorolea9665 pretty sure he's Finnish

Aaah! Thats who he sounded like. ISMO, the comedian. He sounded like someone i had heard before

If they're hardened steel, like automotive grade, yeah. Zinc hardware is super soft.

Even regular hardware store screws are good enough to build houses with.

Everything gets hot when compressed, you're adding energy to the system. However, I agree 100% I want to see how much, and how much it differs per material, because it will vary drastically. So Very interested in that lol

Oh yeaahhh lmao
