There’s a story in the news right now about someone crashing into seven parked cars at the Dallas Stars parking lot but the part I’m interested in is how this somehow ripped a cybertruck in half?? Like clean in half??

cast aluminum ‘frame’ - glorified beer can. cast/poured versus forged/rolled. Forging or rolling creates a superior product versus pouring molten metal into a form. A metallurgist could expound on that for quite a while I’d bet, my understanding is skin deep at best here. Also, aluminum tends to shatter/explode suddenly versus steel/irons tendency to plasticize.
There’s a reason we tend to use the type of frames we use when building trucks; body-on-chassis/frame, and not unibody/monocoque types. There’s a reason those vehicles also have steel as the backbone.
Two heavy duty rails run the length of the truck, with cross members bolted/welded/riveted to it. I think the dumpster is technically a unibody frame, which is body panels, flooring panels and overhead panels welded together to make a cocoon of sorts, but forgoes the two rails that do the real load handling. Meant to be light, nimble, compact, which is traditionally none of the things a truck is intended for.
Looking at photos the dumpster’s frame is a formed, but realisitically flat piece of aluminum, with a basic shell attached to that, that the body panels are fucking glued to.
‘Speed tape’ used by pilots to temporarily patch holes in the sheet metal, probably offers more structural rigidity that the dumpster does.
Fuck, the body panels are of tougher material that the fucking frame is.
Forging or rolling creates a superior product versus pouring molten metal into a form.
I don’t think this is inherently true. You need to skin castings to remove voids and inclusions but if you’re doing work after this I think it is more complex than one just being superior.
forging/rolling removes voids and creates denser grain. you end up with a better product.
I don’t think that makes much difference for something that gets heat treated (because grain structure & size both change). And there is a whole lot of residual stress that comes with forging/rolling thta may be significant depending on what you’re doing.
The induced stresses are part of what can make forged parts stronger iirc (used to work as a designer with a metallurgist as a colleague but, like, many years ago with an intervening drug addiction, recovery, and uni degree so my memory of the technical details is… Imperfect). But yeah it’s a complex topic.
yes, I believe it is the mechanism behind cold working and peening, but I don’t think it changes the grain structure. Definitely a complex field that I am only barely familiar with.
I’m sure it behaves differently in aluminium vs steel, too.
car crash or coordinated terrorism by Act Blue?
Well I see the problem here; looks like the front fell off.
Its a real glass half full situation, did the front fall off or did the back fall off?
Kind of a Titanic type disassembly where the front and back are separated by an act of God, but a mild one like a nice breeze on a hot day
Take all cybertrucks outside the environment
But wasn’t this one built so the front wouldn’t fall off?
(That’s gonna send me down a rabbit hole that I don’t have time for:p)

I found a YouTube link in your comment. Here are links to the same video on alternative frontends that protect your privacy:
The frame is super thin and flimsy cast aluminum. I saw a vid the other day where a guy put the weight of a slightly overloaded trailer on its trailer hook and it ripped the whole back end off
Significantly more durable
To insult the ZyberTrucKKK is a hatecrime!
Makes me wonder how it’s managed to handle or tow the loads I’ve seen put on it ….
Under normal circumstances very little of the weight of a trailer rests on the hitch. But sometimes, like going over a big bump out the crest of a steep hill, a lot more of that weight is suddenly resting on the hitch and the cybertruck is not correctly designed for those edge cases.
not good as a car
not good as an apocalypse car
not good as an IED
Who is this car for?
it looks like a loot crate so my guess is “vault hunters”

The public sector!
It’s the next level disruptive innovation in car safety. Instead of crumple zones, it has disintegration zones
Tbf that’s race cars are built. They shatter on impact to dissipate forces while leaving behind the reinforced occupant shell
Mitosisn’tthe cybertruck appears to be in front, so it would have taken the worst impact, but still I’m pretty sure that the back isn’t supposed to fall off like that.
i didn’t know the undertaker came out of retirement, or that hell in a cell is just a parking lot now.
I hate that I am so terminally reddit brained that whenever I hear or read the words Hell in a Cell, 1998, or announcer’s table, I always think of that shittymorph guy.
Fun fact about shittymorph he was some random unhoused guy in SF that I have almost certainly run into IRL before during that whole saga.
wild. that reminds me of a time i was watching tv in nineteen ninety-eight
That must be where the battery bank and the rear motor mounts meet. Just a couple inches from an explosion.
