Difference between a newton and a neutron. A newton is a measurement of force used against an object, it's a vector since force can be applied in any and all directions. A neutron is a stoichometric sub-atomic particle in materials, which is not positive or negative. Say I push something with 20 newtons of force, it may move, but that depends on the mass of the object, the shape compared to the drag, if we're not talking about vacuum, and friction, if the object is flying or not. AKA newtons are a measurement of physical change in an object, I have not seen anyone do any calculations with newtons and force on a sub-atmoic level, although I've seen stoichometry done, and have done it before. Either this product is magic because it makes forces come from the ether to protect you, or it's low Poisson ratio of the material succumbing to plastic deformation. (Where more material is pushed together with uniaxual stress. Please note that I may make a mistake, and I would be delighted if someone could point it out, I'm open to always learn(Probably with the doings of forces on a sub-atomic level since there is binding and breaking energy, thermal energy, wont get too much into it, but at this level, I'd say I've never seen someone use newtons when dealing with sub-atomic forces).
Never studied materials science, but I did love fluid mechanics back in university. The low Poisson's ratio is an interesting way to think about it. The guy was actually explaining the concept of a shear-thickening fluids correctly, but I have no idea why he mumbled the word "Newtons." The armor contains a colloid (insoluble solids suspended in liquid). When subject to no or low rates of shear, it behaves as a fluid because the suspended solids are able to "get out of the way" as the mixture deforms. Beyond a critical shear rate, the solids cannot redisperse fast enough and end up clumping together. So if instead of "Newtons" he had said "polymer colloid" he would've been rather correct!
So do this: take a tack hammer and whack your knuckles with it. Hurts, right? He gave a reasonable demonstration, and screwed up one word. (Maybe he meant "molecules"?) As a motorcyclist, I'm interested in anything that can effectively dissipate impact forces. And, @KevStar, I think you meant "break", not "brake". See? It can happen to anyone. Sheesh.
He meant molecules, but he said “Newtons” instead, because he was talking about non-Newtonian fluids. I came here to see if anyone else caught on to what he said.
Just FYI to everyone....these aren't some new, high-tech untested prototype thingies or whatever. They've been in production for years now. You could certainly get your hands on one of these relatively easy. They're commonly used in sports or motorcycle protection, and I know some work gloves have these materials, too.
it would be cool if we could buy sheets to shape and use how we want to suit our needs since i personally need something a little different to enduro or motocross since i race speedway sidecars i need some seriously good impact protection but i also need to be able to move around very easily
@@midgetman4206 I don’t see how cutting what is essentially a sheet of foam would decrease its original protective properties, but so far I haven’t seen anyone try it with D30. You or someone else would have to test the material out for yourselves.
I placed my hand on concrete, put my pad on my hand and hit it with a real hammer and it hurt like hell. My finger swelled up a bit and I had to ice it so it would stop hurting
The gel is not how the actual product is sold or used. Put on a glove with D3O and try a hammer, that a real world test, not something that now of us can actually use.
@@chrisawesome3091 From the way it handles, It looks exactly like some science putty stuff that I have from when I was younger, I think it was from the science museum. it was the exact same color and all. It is actually very good at dissipating energy, however I don't think the pads would have the same properties as they seem to be made out of some other material and not putty.
Non-Newtonian fluids are fluids that don’t follow Newton’s Law of viscosity. The law basically says that the viscosity is independent of stress, which is true for fluids like water, gasoline etc. cornstarch slurry is like the most well known example of non-newtonian fluid, but there are other common examples too like honey, blood, lava, toothpaste, mayonnaise etc.
problem... Y'know the saying "It's not the fall that kills you, its the sudden stop"? This would make the stop even more sudden. Also how does it go from being goo to- staying is a shape without slowly becoming a blob?
Dude, I’ve watched this basic demo on numerous videos. Why don’t they ever do the test with the actual armor instead of the foam? It sitting right there! And the ball bearing this is misleading and does not really correlate with real world uses. Just fishy.
Does the Endura MT500 have the extended utility with Judo, volley ball etc? I currently use Mizuno volleyball knee pads which have gel but it's not D30.
Unfortunately no it would act like a rock when you hit a bump, basically making your car wobbly and boat-ey normally and then it hits bumps like it has no suspension. I see what you were thinking tho, for that application we would want something with more elasticity. Look into cheap bicycle forks/shocks some of those use a plastic/rubber insert as a suspension the way you’re thinking of using d30
Wow, He tapped his hand with the tiniest soft mallet in existence, and his hand didn't brake. Amazing! 🤣🤣🤣
LMAO!!!!
Hands are definitely needed for braking 👁️👄👁️
The smalless hammer they could find... that really represent well the hit you get from hitting the dirt at 50kh/h
"... newton inside the product are free flowing..."
me imagine many little Newtons wandering ahahah
I’d love to see a hatchet 🪓 used, since it seems most surfaces that cause me problems are sharp/jagged.
"It's called a non-Newtonian substance, which means the Newtons inside the product […]" => seriously? :facepalm:
I heard "newtons" as well, but thought his accent was messing up "neutrons," which also seemed a little weird to me, but I'm not scientist.
Lol this is hilarious.. He should know what a non-newtonian fluid is if he's going to state that his product is one. LOL

I cant stop laughing that "hammer" is definitely not what I call a hammer
He meant molecules.
So what happens if you actually fall, we don't get ball bearing and ballpeen hammer storms around where I live.

You can buy solid or mesh sheets of D30 online. From there you can potentially cut them to shape and modify them.

It spreads the force of the impact throughout the material. This also means that more material = more protection.

Because it obviously doesn’t work, it’s a scam.

If the pad tears a bit, can you glue it back somehow?
"Newtons inside the product are free flowing" - must be really small Newtons, micro Newtons, or uN.
can d30 be used in vehicle suspension?
Unfortunately no it would act like a rock when you hit a bump, basically making your car wobbly and boat-ey normally and then it hits bumps like it has no suspension.

that hammer couldnt break a bone if you tried
But it will still hurt
''As you can see its a 'hArD hAmMeR'
Shows the hammer : 💩
"hammer"
My goo also hardens on impact 💀😂
It stil bounced up pretty high...
They always demonstrate with the goo, so it must be stronger. It probably gets weaker when they turn it in to the foam
The question is if it even works since we never see them demonstrate on the actual products.
