Those U walls and supported walls models are a brilliant way to show how force transfers over a wall... in the slow motion, we can see that the pieces that took the biggest hits are actually the ones at the back, it's fascinating!

I suppose it could be viewed as them taking a hit, however I was considering net force and would say they had the most force transferred to them through the system. All of the walls pushed against each other on the axis of the hit, and those pushes were all equal. That meant when the ends didn't have something to push against them they'd fly away however they still pushed against the sections of wall that are still standing. Absolutely love this kind of interaction and am rambling a bit, sorry :)

These tests were done on a baseplate allowed to move freely against the floor. This made it so a significant amount of force was absorbed by the baseplate tilting, which is unrealistic in lego war situations. It is very likely that the cannon would have more penetration power if the baseplate were bolted down (or otherwise fastened) to the floor.

@@runtergerutscht4401 Not really, think back to high school physics class. One of the rules that's battered into your head is "any force will have an equal and opposite force applied to the object exerting the initial force". In any given impact, the ball is exerting force on the wall backwards (toward the lego man), causing it to either slow down or to cause it to go flying the other way. The walls accept the backward force spreading them throughout themselves and anything they're attached to, creating a downward force on the base. The downward force on the plate causes an upward force on the plate, causing one of two situations, either pushing the wall up, surrendering the wall to the initial blast backward by the ball, or the walls hold, allowing the baseplate to push off of the table, creating an upward force in the baseplate itself. (There'd also be a backward force on the baseplate, since it's attached to the walls until they pop off, but I'm going to assume that the baseplate was stopped from going backwards, somehow.)

I think this is because the cannon is limited by the maximum speed it can get the launcher to move. The balls all leave the cannon at similar velocities, so more energy is transferred to speed up the heavier balls instead of being lost in the cannon when the launcher hits the front. As the projectile mass approaches what the cannon is capable of moving, I think we'd see diminishing returns on how many walls it could breach.

Great observation! some quick data analysis reveals that the number of walls is approximately modelled by n=m*sqrt(x), where n is number of walls, x is the weight of the ball, and m is some constant coefficient. The coefficient m for the double wall was exactly double that of the quad wall, but the other coefficients didn't have any nice relations. For those curious, I plotted the transformation z=sqrt(x) (square root of weight) against n and got a graph that was roughly linear (I tried a few other transformations, such as logarithmic and cube root [single wall fit a cube root well], but square root seemed the best fit across the board). When you have the "linear" graph n=mz, you can calculate m by doing rise/run and compare the model to the actual values. The model for the double wall was the "nicest" because comparing theoretical values correctly matched the actual values (after rounding) 2.12035979898674 3.37485975740272 5.99728316967547 8.12035979898674 Obviously many things made certain points deviate from the trend, such as the discrete nature of n, the fact that the kinetic energy may not have increased the same for each ball (as the cannon would eventually reach a limit where the increased weight would absorb all kinetic energy of the elastic bands, meaning any extra weight would have the same KE), and the fact that the flexible floor absorbed some impact, to name a few things.

Anyway I would like to test a model : The potential energy E0 in the rubber band, that will be given to what is attached to it is a constant (doesnt depend on the mass of the ball). The energy lost by friction with lego thing in contact withe the ball is also constant Ef1 = F*L where L is the length of the ramp. Let's say E0 - Ef1 = E1 (it's a constant). The energy lost by friction with the ball is proportional to its mass, Ef2 = k1*m (may be it's less than a proportional model but not more, because if the ball starts rolling in the ramp, the friction decreases). May be we can negelect this contribution. Then the remaining of the mass E1 - Ef2 will be given to the ball (E) and to the lego thing attached to the ball (E') that also moves at the same speed, proportionnally to each one's mass (m and m') : E/m = E'/m' and E+E' = E1-Ef2 E = (E1-Ef2)*m / (m+m') E = (E1*m - k1*m²) / (m+m') We can use this model supposing that the number of wall destroyed is proportional to E : n = (n1*m - k*m²) / (m+m') This model shows that there is an optimal mass to destroy the most walls (which is quite realistic, even though I don't know if a power between 1 and 2 on m in k2*m² isn't better than 2). I suppposed that the pulling force of the band was bigger than the friction. But the contrary is totally possible and this is where the model gives negative values. It should be n = max(0 ; (n1*m - k*m²) / (m+m')).

Love to see a video which goes straight to the point without tons of jargon or other unnecessary things. Gotta like that.

This video is actually a great example of how spaced armor works on tanks.

theres a lot of good practical physics in this video, pretty cool

the last wall is the true engineer's solution.

The nerves of steel on these soldiers is incredible.. 👏

3:06 the side walls popping off, but front walls standing is some loony toons shit.

No it’s because the force was transmitted to the ends of the walls

Would be interesting to see how the wide walls fare against multiple lighter shots, once the connecting bricks have been damaged/blown off I assume that the wall is weakened substantially at that point.

If only he taped the base plate to the table for accurate force dissipation

This is a great physics lesson. Should be used in school.

I love your videos. Perfect content - no commentary, just great footage. Thank you and I subscribed instantly.

1:46 only that flat 1x2 went flying!

I just love seeing a set of walls hold up to a shot, then the next level shot crushing the Lego king in a pile of walls. Made me giggle every time.

2:28 my argument when someone uses 🤓

This was really relaxing to watch morning before work, nice vid

Watching the walls jump out of their spots from the impact is really, really satisfying, especially in slowmo.

That poor castle will make a good historic site in 500 years.

This video goes straight to my favorites. I love the editing, amazing 👏

Huge respect to the knight who get crashed by the walls many times

I remember the days of eld where Knights were so chivalrous to one another, they allowed the enemy Ballista to get within 7 bricks of the wall before firing.

Love how the wall simply split in half at 1:07

We used to make these back in the day, the draw was manual though, as this was the early nineties. We all built a fort, occupied it with the lego toons, and then wreaked havoc on each other. We called them smoothie guns because of the need to use the smooth tiles on the firing track. Good times.

Straight to the point No intro no explaining just pure content 🔥

2:36 lol ablative armor

3:27 new sets functions be like

I'm now convinced lego is the strongest substance in the universe

This is quite a good demonstration of why when guns were becoming more important in siege warfare smaller but larger walls were prefered

It's interesting how there is such a difference in the outcomes between the last failure and the success. One might imagine only one wall remains standing, but often multiple walls remain in place despite each having fallen without the final support added.

I like how when the walls fall over it sounds identical to lego breaking in the games

Real MVP here is the knight for being the test dummy. Poor guy must have had such a high hospital bill

This is peak content. Absolutely beautiful.
