you just need 2 Tanks I guess xD

[@casey6556]

I’d argue this still proves they’re impossible to separate. The tanks didn’t separate the books, they ripped the pages out of their bindings.

[@YouNoob93]

Looks like about half the pages were separated and half were ripped

[@sola7112]

If these tanks had been pulling on a block of solid wood, it still would have broken at some point. I don't think the interlacing failed, they just reached the limit of what phonebook paper can handle in general.

[@AchtungBaby77]

I was just thinking that - the pages didn't separate at all!

[@shone.nelson]

I have a different theory to this. It is true that it is impossible to separate the 2 interlaced phone books. That is due to the material of the pages which has totally inconsistant frictional points on their surface area. Like you said, the tanks could only rip it off. If you were to bring a hacksaw you could rip it off too. But that's not the point of this mission. My theory is, instead of pulling the pages outwards, one should push it inwards causing it to separate a tiny little bit from it's frictional points. Then twist and turn from the center in the opposite directions for each books. This will separate it one page at a time.

[@Neimit]

If you slow it down, most of the pages seem to slide away and not rip

[@Falkano]

@@SimonWoodburyForget you just took the mass of the tank but actually its not quite that simple. you take the mass (62,000kg) and multiply it with the downward acceleration by gravity (9.81 m/s2) and the traction coefficient of a tank tread on pavement (some googleing gave me 0.8). Then you multiply that by 2 (which you also didnt) because two tanks are pulling. That gives you 973,152 Newton or 218,773 pund-force. Divide that by the 8,000 pounds the phonebooks resist and you get to just above 27 phone books. So it takes 28 (or in reality 28 phonebook *pairs* so 56 phonebooks) to get the tanks to spin. One caveat: i absolutely failed physics in high school so this might be absolutely wrong. Pulled all of this from the internet in an attempt to reeducate myself :D So if anyone knows better feel free to correct me. I am certain though, that your solution is not correct.

[@ivanmanko]

@@Falkano One correction: you don't really have to multiply by 2. If Tank 1 can pull with X force, it is impossible to get more force than that in the tension of the phonebook. If the Tank 2 is heavier and can pull the first one with more force than X, Tank 1 would slide while the tension remains X. It is easier to see with an extreme example: if on one side you have a tank and on the other you tie the chain to a coffee mug, the tank will never break the chain, because the force it can produce, the tension to witch it can submit the chain, is limited by the drag of the mug on the ground. So the tension is limited by the weakest "link", it does no double. (I am writing this instead of an essay on extensiometry that I have to send tomorrow... Please someone kick me out from KZbin )

I surprisingly really like the amount of bass in this video

[@drawingguy2003]

Umm, the tape was there for several reasons. One is to keep the brown paper from flapping and revealing the branding of the phone books, and second to prevent the books from flopping open and delacing the pages. The point was to pull them apart, not flip them apart. The tensile strength of the tape/paper cover is fractional compared to the phone book themselves, so has little bearing on the experiment.

[@KelvinSmoke]

It does have to be "de-weaponized" because the NFA considers it a destructive device. This generally includes a concrete or welded steal plug, the removal of aiming mechanics or fixed to a straight position, and removal of any main gun breach parts that can be removed. I have heard that some states require the removal of engine armor.

[@konoyarogaming6774]

That is correct

[@bradsimpson8724]

Schwarzenegger went through the Austrian military to find the very same tank that he operated during his Army service in 1965. The tank that he owns(and does quite a few charity events with) is the same one he was driving when he was 18. It had to be disarmed(obviously), but there was an interview where he said that the logistics of physically getting it from Austria to the US far exceeded the difficulties with paperwork and permitting.

It's because of air pressure off each page. the stacking of page close enough makes no room for pages to move as there is no air. The tight pressure in between pages makes it immovable if detached all at the same time.

[@Zerodghjj]

I found this so unbelievable. Where the hell did they find phone books?

[@Bastista1]

R.I.P. Jacques Littlefield.

[@rontocknell3592]

Alternatively, they could be separated by one person... maybe even a child. It isn't just friction. The friction helps, of course. It provides just enough grip to provide tension. The tension increases as the force increases (and yes, it is like those finger things). So the way to do it is to lift ONE of the phone books by the spine... and waggle it. As you waggle, the other phone book suspended from it will gradually work loose and, eventually, fall to the ground. Try it. A perfect challenge while self isolating because you don't need two people. Heck, you don't even need two hands. Now, that's Zen for ya.

[@ledrash6079]

I was just gonna say this and with the fact the mythbusters didnt bring this up at all.

[@JVSkellington]

By doing this you would be creating gaps between the pages, which would decrease the friction. That's the same reason they taped the covers, so they wouldn't start separating while they tried to pull, except while wagging you would do this randomly inside, instead of starting from the outside.

[@Tango_Hendrix]

I thought they woulda did the hood myth that duck taping a phonebook to your stomach can actually stop a knife stab to your gut. 😂

[@Logarithm906]

Newtons 3rd law. The pole they tied the rope was providing a static force that equalled the teams efforts. So say 2 teams of 5 men pull with 1000N of force against each other, only 1000N of force is going through the books. But 1 team of 10 men can pull with 2000N while the fixed pole provides the exact force their exerting in the opposite direction (until it fails, i.e. bends over or snaps).

[@GenEchoEntertainment]

Probably this: when you're doing tug of war, you're not applying constant force, you're counting one, two, three, and so forth. To have the two numbers equal, you'd have to have them both pulling in the opposite direction in sync. Plus you have to take into consideration the loss of traction and other such human factors when you have something resisting/pulling in the opposite direction.

[@afewfairthings]

Strictly speaking, those phonebooks were torn apart, not separated. Big difference cos the former is material fracture. Had the paper been infinitely strong (i.e., untearable), it would be literally impossible to separate the two interleaved phonebooks. See journals.aps.org/prl/abstract/10.1103/PhysRevLett.116.015502

What I'm thinking here, since this was supposed to be a friction test, it is plausible, if not confirmed, since the tanks mostly ripped the books apart, meaning you can't get the phone books apart while keeping them intact, meaning this setup summons an enormous amount of static friction. Just my opinion, though. Saw a test like this when I was younger, where they used two quads, except then, one of the books' spine got ripped off, while the pages remained interwoven.
