Tire Runs A Red Light And Gets Pulled Over

ChaosEngine says...

Why the hell does he move out of the way of the tyre?
He's stationary, but he pulls out into the intersection to let the rolling tyre past potentially causing an accident.

So, some smartass went and reinvented the wheel ...

jubuttib says...

I think that at best this would be applicable only to the very lightest of electric vehicles (something in the "motorcycle" weight class, even half a ton is probably too heavy), and I have my doubts about even those, even when completely disregarding the sideways forces.

With a system like this you do not want more than a few cm (about an inch, at a guess) of suspension travel from when the car is lifted in air to the car at rest (= 1G vertical load), just from the weight of the car compressing the springs. If you have more the springs (which the loops naturally are) have to compress a lot with each revolution, which strains them, heats them, isn't good for rolling resistance, etc.

If we assume a 1000 kg car with a 50/50 weight distribution, to get about 2 cm of suspension travel the spring stiffness would be about comparable to a high level GT racing car. Comparing to high level sports cars, the street going Porsche 911 GT3 RS car, which is regarded as a pretty stiff, racy and track oriented vehicle has something in the region of three times that much travel, a normal commuter car can have way over 10 cm due to soft, comfort oriented springs.

So you can't spring a proper car with just these because it'd require it to be too stiff (also I can foresee shock absorption issues). Another problem is the 360 degree springy nature of it. You really don't want car tyres to move much aside from up and down. These have the problem that when you brake, the forces will try to push the axle forwards in relation to the wheel (i.e. the wheel moves backwards while braking), and the reverse when accelerating. You'd be (possibly) drastically changing the wheelbase of the car during acceleration and braking, which could have catastrophic results for handling in extreme situations. Many if not most cars these days are capable of braking at over 1 G, as long as they have decent tyres, so the front-back movement could be bigger than the up-down movement.

So yeah, doesn't really sound like a workable solution as the ONLY spring system on a car. Having some springiness in the tyres (either in the wheel itself of just having larger profile tyres, like we used to back in the day) can be helpful for comfort and even handling in some cases, but springing the car only via the wheels isn't a good idea, you really want to be able to control the wheels better than that.

If they do well, perhaps this is a way to eliminate suspension in electric vehicles, reducing weight but keeping a smooth ride.

Arrows A22 F1 car vs other track day cars at Circuit Zolder

It doesn't say, but you can tell from the helmet that it's Arnold Wagner of Germany. The video is from 2012, and there are some other vids from around the same time.

Rennwerk GMBH use this car as a mule for their tyre temperature sensor testing, and have pictures of it all over their web site, and some other videos.

Any idea who was driving the car on this occasion? Takes a strong stomach to race such a fast car against all those slowmobiles!

judge dredd-interrogation scene

gorillaman says...

No man, that body armour, those boots...I'd harvest the bones of a thousand murdered infants to build our bed if that's what it took. Do you think that's what she wants?

I had to go rewatch this. It's practically perfect. Not an origin story, no romance subplot, no compromise. Just a day in the life of Judge Dredd. Love it, but my favourite Dredd story was told in rhyme:

They'd been waiting there since nightfall for the Sharks to come along,
They knew they'd have to pass this stretch of street.
So they'd sharpened up their stickers and they'd brought along their bars,
And they were wearing steel-tipped stompers on their feet.

There was Big Frank Zit and Faceache, Crazy Joseph with his spear,
The Dixon Boys were there and Billy Rat.
Ike the Spike had brought his sister with her homemade ghetto blaster,
And the Ghoul had put new rivets in his bat.

Now it wasn't nothin' personal that they had against the Sharks,
Any bunch of dead-end spugs would do.
'Cos there was nothing they liked better than to mash and bash and stomp,
Same as any normal Mega-City juves.

"A-rumbling! A-rumbling! We love to go A-rumbling!
("AAAH!")
We love to lay in ambush in the night!
("AAAA!")
A-rumbling! A-rumbling! The Zits were born for rumbling!
(SMAK!)
There's nothing we like better than a fight!"
(KRAK!)

Then a headlight pierced the darkness - a rider gaunt and grim,
Daystick drawn and ready in his hand.
     The chin belonged to Dredd,
     And the voice as well, which said:
"You creeps can do your rumbling in the can!"

"It's just one judge!" cried Cindy Spike and opened with her blaster -
"I'll send him back to Central in a sack!"
(SPOING! "AAAAAAA!")
But Dredd's bike absorbed the blast and laid her on the street,
With tyre marks running right across her back.

Then the judge got down to business and his daystick rose and fell,
Striking out at every head he saw.
For though the Zits launched the attack, the Sharks were fighting back -
And self defence is no defence in law!

As the heap of bodies mounted, Big Zit could see his Waterloo,
Waiting just one station down the line.
Oh, sure, he loved to rumble - but he preferred to be on top...
"Let's scram and live to fight another time!"

("Dredd to Control! We got forty-plus juve rumblers fleeing east through Bernstein. Zits and Sharks, back-up required."
"Wilco, Dredd!"
"Med squads and meat wagons to Moreng Alley. Estimate twenty casualties, more to follow."
"Control to all units area Bernstein. YPs on the run."
VRMMMM!
"Pick 'em up!")

In the space of sixty seconds there was a judge on every street.
From watching bays others scanned the slab -
"We got two Zits runnin' fast though the Tamblin Underpass!"
"Krupke here! I got 'em in the bag!"
(THUNK! THUNK!)

They cut them off at Sondheim and they mopped them up on Wood,
On Pedway 12 they corned Crazy Joseph.
He tried to make a stand - but a spear's not worth a damn,
When it's up against a judge's high explosive.

The Ghoul surrendered quietly, he didn't have much choice -
Ike the Spike tried to scale the sector wall -
("Save your bullet, he'll never make it." "Oh no! AAAAAAAAAAAAH!" SPLATT!)
The Dixon Boys all copped it when they tried to hitch a ride,
On the 2020 Zoom to Bernstein Halt.

Big Zit thought he'd play it clever, the law was everywhere,
The safest thing for him to do was hide -
Dredd tracked him down on infrared - "Don't bother to come out!"
"The best place for trash like you is inside!"

In minutes flat they'd caught them, every Shark and every Zit.
To Dredd it fell to ladle out the years -
"Twenty years apiece for Cindy Spike, Billy Rat and Ghoul."
An extra ten left Big Frank Zit in tears.

For Faceache minus half his face, for the hapless Dixon Boys,
For Ike impaled so cruelly on his spike,
For Crazy Joe with his gaping hole, there'd be one final rumble,
Along the last conveyor belt at Resyk.

A-rumbling! A-rumbling! They loved to go A-rumbling!
But the Zits will go A-rumbling no more!
A-rumbling! A-rumbling! They loved to go A-rumbling!
But they should've known they couldn't buck the law!

VKV City Racing 2014

oritteropo says...

http://www.cityguiderotterdam.com/events/festivals/city-racing-rotterdam/

It's a free demonstration event rather than an actual race, but the whole point is watching the cars (including F1 cars) and plenty of tyre smoke. It costs €77,50 (for adults, or €47,50 for children) to sit in one of the grandstands, but there is a free section as well.

I so don't get it. I have to assume they are somehow acknowledging/thanking the fans with this type of display(as i often see them do as the winner of a race).

Meh, that dude is an idiot with more money than sense. I wouldn't help him either.

Sell your shiny-arse SUV and buy a real 4wd (hint: if the rims are bigger than the tyres, you're doing it wrong)

Gendered Marketing

ChaosEngine says...

Well, first of all, I said "most", not all. Second, I'm not making any value judgements, simply stating my experience. Most women I know spend varying amounts of money on products designed to keep their skin soft and hair free etc.

Who doesn't want to be perceived as competent? Plenty of people. I know lots of women who profess proudly to not being able to change a tyre. To be fair, I also know plenty of women who are extremely competent, but I know almost no men who would admit to not knowing how to change a tyre.

Again, I'm talking in broad generalisations, and that's how marketing works. I'm not saying women can't be tough or competent or that men can't have soft skin, but that is not the norm and marketing is targetted at a wide demographic (unless you are specifically marketing to a nice audience).

As to the question of whether these distinctions are ingrained or not, it's largely irrelevant. It's not about some genetic marker that makes men want to smell like trees and women smell like flowers, it's about centuries of built-up cultural aesthetics. I don't really have to explain where this comes from, do I?

Again, I'm not saying this is right, merely that there are reasons that marketers do this. Where I have a problem is when it becomes exclusionist. When girls are told they can't play with "boys toys", I say screw that.

Jinx said:

Ok. Women want to be perceived as soft (they do? - I'd be careful with that generalisation, your straying into damsel territory there) and feminine (Surprise! ...but what is feminine? - is it soft and pink or something else?). And who doesn't want to be seen as competent and why should it be seen as a masculine trait?

Wait, Let me guess the guys. Do most guys want to be perceived as..masculine...and...*insert positive gender role stereotype here!*.

Oh well, I was close I guess.

So liek. Yes. Your average guy or gal wants to fit into their associated gender role, or gender aesthetic if you like. But it seems to me there is sort of an element of carts before horses here. Are those gender aesthetics a preexisting difference between the sexes or is it an arbitrary divider created by our society through cynical marketing campaigns that have exploited our desire to "belong" to make more money?

Aside from that, what exactly makes a fragrance "tough" or "competent"? I've never thought to describe a smell as competent in all my life. It's all as arbitrary as pink for girls, blue for boys and...pens for women.

The Mountain deadlifting 994 lbs

Unfortunately, it seems that anything I do these is old school by default

And it also seems that quoting a spoiler tag makes it visible.

@Payback, that's not sad at all. Clearly you need expensive tyres when using them as a deadlift weight.

Formula 1 Pit Stop: 1950's & Today

jubuttib says...

Would be difficult to swing that because F1 didn't have the type of organized pit stops we see today until much much later. Refueling during a race was first done in a properly calculated way in 1982 by Brabham, before that they only did it in emergency situations (barring Fangio's German Grand Prix win in 1957, where he just decided to do it mid race, but would probably have won even without it). It was again outlawed by 1984, and came back in 1994, then went away in 2010 again, so the only times in history that proper pit stops with fueling etc. have been in common use in F1 are between 1982-1984 and 1994-2009. Likewise stopping for new tyres pretty much came in with the fuel stops in 1982, because naturally they realized they could run softer tyre compounds if they only had to last half a race.

In the 50s, 60s and 70s you'd basically only see the F1 drivers pitting in if there were problems with the car, for the most part they really really wanted to avoid coming into the pits if at all possible. Exception being races like the Indy 500 which was simply too long to complete in one go.

Slightly more interesting would have been seeing a pit stop of an actual F1 race from 1950 since they would have had a different governing body and probably different rules.

How To Make A pancake Out Of A Land Cruiser

charliem says...

I dunno, if you were the engineering manager in charge of the stock there, and saw that they wanted to run over a hilux with $mil+ tyres destined for refurb.....would you take the risk that the already end-of-life tyre wouldnt collapse and cause damage to the superstructure of the cat?

They are worth a bit more than the tyre even....just a thought.

coolhund said:

Yes, I am fairly sure they dont do burnouts with them either........

You mean they always reuse them? Even if they are already damaged?
Every material has its limits and cant be recycled until time ends. Maybe it was time to get completely new ones. You dont know that. But I do know that people who use expensive equipment like that, very rarely treat it like that unless they are allowed to or have a reason.
I mean they surely knew that that wreck would be seen by their superiors and a lot of people were involved.
