Some kind of metal wheels, or a certain configuration of a ball bearing mount (that I can visualize but can't describe because I don't know the correct vocabulary) would be even better. Ultimately, it would be self-defeating because if you are all hugging the wall nobody could pass each other.
@@LloydsofRochesterit would have to be like hidden panels of wheels or bearings on the side that would deploy at the press of a button like Speed Racer so nobody else would know about the tech and replicate it lol
Good news Hank, NASCAR has said that as of this moment they will not be making the wall-hug move illegal, as it can only work at a few short tracks and it can be blocked by the leader hugging the top. ...You'd have to be willing to risk your car to block but a win is a win!
Yeah......but you don't have to employ the strategy for a whole race just lag behind in decent position then crash into the wall and gun for glory on the last 1/4
@@flyingpigmonkey1 If that ever happens. The cars are much safer than they were 21 years ago when Dale died; however they need to figure out the impact force transfer issue in the new car, as they made it sturdier, but that means the vibrations from impact in the rear of the car are felt by the driver more than the last generation of cars. And we've had some gnarly wrecks since 2001 that the driver has walked away from.
@@flyingpigmonkey1 did no one ever died in a NASCAR race then? Because with your logic after the first fatal accident they should cancel the races and make them illegal
yeah, when you don't actually have to worry about a real car your your real legs being shattered to pieces you can ignore part of the physics equation of speed around an oval track.
...speak for your non talented self.... i can actually drive online n dont have to resort to such bs tactics... This move pissed me off to no end, cuz it validated you talentless drivers out there. #1 issue w/online racers, they dont know what the brakes are, and they will use your car to stop, vs using the brakes. Nothing ruins an online race more than seeing this talentless behavior take place. I'm glad NASCAR did the right thing n banned further use of this. Like i wish the online racing communities n developers would as well.... Funny how many people practice doing this kind of move online to perfect it... vs u know... actually trying to perfect using the brakes and actually turning.
@@Soli2deYT I've been sim racing since you were a twinkle in your uncle's eye, boy! Now step off your high horse and marry her for God's sake! You've been living in sin for too long!
Why ? Making this illegal would cause more problems than it would solve. You have to be able to rub the wall while passing without the race being called. This is Nascar not pussy foot.
@@anonymousperson7889 there's a difference between rubbing is racing and flooring it into the wall in a turn and it's pretty easy to make the distinction and make a good rule accordingly. That being said I would prefer it stays legal
@@cjhowell6406 it is too expensive and dangerous to stay legal. especially if multiple people do it at the same time. if one of the front cars damages the wall so that it sticks out a bit and then the next ones front is hooking into it, then every car behind him is crashing into him at full speed. and the wall is far from being smooth. he himself said that he was lucky that the car didn't hook at the gate that let's the cars out.
@@dovos8572 with all due respect i think you just don't understand or recognize that racing, like professional fighting, is meant to be a brutal and dangerous blood sport. illegalizing winning dangerously turns it from a race into a lame little bumper car bs
"I do, I understand. And I can make it so you understand too. Let's do it!" This is precisely the attitude of an amazing teacher. I wish we had more good teachers... I wish we all valued teachers so that we would have more good teachers...
Racers don't just stay on the inside. Race cars try hit an apex. They start wide, go to the inside and go back out. This maximises the radius of the turn. The centrifugal force required for a (circular) turn is inversely proportional to the radius and proportional to the square of velocity. Your centrifugal force comes from the tires, and has a limit given downforce and tire condition, so you have to optimise speed and radius. Make your radius bigger, go faster.
Pedantry corner: You're referring to centripetal force. Centrifugal force isn't really a thing, other than a way to describe inertia affecting circular motion.
@@davidcarlson399um, yeah NASCAR drivers do it too, ever notice how they start high at corner entry and slow down as they approach the bottom and end up high again on corner exit? Thats an arcing turn with hitting an apex.
Ross Chastain's Wild Wall Ride was a once-in-a-lifetime moment. He did this on the final lap, not caring how much he destroyed his car in the process... and it bloody worked. I've been watching NASCAR for almost 30 years and nothing, but nothing will ever match this man's crazy, inspired, Hail Melon racing move.
Greatest moment in NASCAR since Dale’s “pass in the grass” moment. I grew up on NASCAR - was actually named after DW, we had a Winnebago and followed the tour up and down the east coast. I met all the 80’s greats as a kid, and loved it. My dad passed when I was 8 and we couldn’t keep it up - but I still watched on TV every Sunday with my Grandfather. Lost touch with it over the past 20 years or so, but seeing this viral moment really took me back. So cool!
It’s a great quote, but he didn’t explain the reason it actually worked. Yes, a larger radius let’s you carry more speed, but not twice the speed of your competitors that are actually taking the largest radius available to them (outside-inside apex-outside). The reason he was so much faster is that he was able to use the wall to overcome the grip limitations of the tires and help him follow the corner despite pulling 5.5G in a NASCAR.
The real physics problem being: your chassis can only handle one of those before your "new" suspension geometry is now unstable and at 200 mph that's definitely a thing..👍
At Martinsville Chastain was going 130mph on the wall. The track is too small for 200mph speeds to be achieved. Larger tracks like Daytona see 200mph kinds of speeds.
Also important is how low kinetic friction is compared to static friction. Since the car is already moving fast, the coefficient of friction stays small between the car and the wall. Looks like he almost caught on some of the supports, though. That could have gotten ugly.
This is, for sure, the flashback scene of some future NASCAR anime... where the right-hand side of racecars get armored up in order to hug the walls and crush any car attempting to do this past them.
@@ggbooliano there already is like...two that i know of off the top of my head. They also just add a lot of combat. There is Speed Racer; and then there is one i cant remember the name of that if like deathrace and speedracer had a baby and then put it in a mech suit.
@@xSaraxMxNeffx There was that absolutely awful Nascar sponsored CGI thing. NASCAR Racers. With the ROCKET car, and the FLYING car, and the CAR WITH A FRICKIN BUZZ-SAW. And these were just the good guys.
I tried to explain this concept to my secondary school PE teacher a few years back and they didn't get it so in our 200m sprint we didn't have staggered start points so the people on the inside won by a good margin. Absolute bruh moment
@@arthurguerra1079 that wasn’t an accident, that was “forza motorsports 3” tactics right there. He must be a veteran because that was some smooth wall huggin
It's like the damn Mexicans when they're playing football and they have a goal they go crazy because that sport also is also stupid and boring when a squirrel goes by the field they think it's the most amazing thing that's ever happened
yea like that's the move you pull when your mechanic has been sleeping with your wife. you make that motherfucker have to do a shitload of body work XD
He's not riding the wall constantly, only in the turns & steering the tires helps that friction to be less extreme, as well. Tire gripping becomes largely irrelevant by using the wall to help hold the car in it's line along the wall. Fuel consumption must be calculated differently since you'll be running flat out, though. You could even mount skid plates along the right side of the car for protection & managing friction. Traffic getting in the way can also be a potential issue needing to be dealt with. 😀
ya i raced oval track for quite a few years. never in a million years thought that would actually work. would have thought grinding on the wall would have scrubbed too much speed and sucked him harder into the wall
Another way to go faster is to follow the car in front of you so you catch their splitstream (less air resistance = faster car) Also going always on the inside isn't always recommended and you'd rather take a racing line (which includes aiming for the apex
I love the fact that he can't explain it, despite the fact he's the one that crashed into the wall! He must have gone "well I don wrecked may as well max my speed out" weren't you there
He needed two spots and made a hail mary. His only chance payed off, but why his car was able to continue moving fast enough nor get caught up on the wall, well that he cannot explain.
@@Thatguyujustmet wall friction is less than the friction of the breaks on the wheels would have been, or it’s more and he can just floor it this way so it just powers through.
@@vexedpixels he could have lost a lot more speed to breaking than he did to grinding against the wall, or he managed to go fast despite grinding against the wall because, no longer needing to slow down to avoid crashing, he could use the full power of his engine.
No change at all will happen, Nascar said no need to change the rules. The issue is that move severely damaged the car and can only be used once (the final lap), but if more then on person uses the move it’ll probably end up with a small pile up and obviously you’ll lose. This is what we call in the business a self correcting issue. I can see one or two people using this move with little or no effect and I doubt it’ll make a significant change
@@buttburp6995 doing it more than once, maybe twice, a race is going to result in damage to the car that will make it too difficult to control, and the tires will either blow out, or get cut. It is really only a last lap strategy at maybe 3 tracks.
A corner of an oval.... Hmmm... Interesting theory... I get the feeling that you skipped kindergarten if you don't know your basic shapes... Maybe RU-vid isn't the place you should be hanging out, buddy.
@@lyntonfleming they meant the corner of the side railing. The track's railing isn't just 1 solid piece, it's several connected pieces. If one of those pieces is slightly misaligned and a corner juts out, your car could catch that and, at best, cause you to spin out. At worst, your car turns and tumbles, sending you flying straight into the next wall at high speed.
I'm slightly amazed that a NASCAR driver doesn't think he could explain it. Top professionals tend to know a ridiculous amount about their sport cuz they have been practicing it and studying it for decades trying to win at it.
Fun fact. Due to the fact that this wasn’t illegal when he did it (because they never thought anyone would actually do it), they gave him the position and allowed it, but then after the fact said “okay he found the loophole, but now that we know it’s there, it’s now against the rules” and you can’t do it anymore so Chastain is the first and last driver to ever successfully complete a wall ride like that
Don’t forget the super speed ways! You have to pass in a pack - or you’ll lose speed, drop backwards, and get passed by the cars behind you (instead of moving forward and passing the cars in front of you). So, there’s more to it than just your speed and location on the track.
Don't forget the race strategies. You to adapt your strategy with changing race condition and event on track. Do you want to do a pit stop or not if safety car/pace car come out. Losing position now and try get it back later with a fresher tyres. Or try increasing the gap just enough for a pit window before the tyres are out. So, there is more to it than getting a tow from a car infront.
you've become the physics teacher that everyone likes cause you're making physics easy to understand. which with a bad teacher can be made very difficult
To be fair, Hank keeps things extremely conceptual and at times somewhat vague. The study of physics is mathematical in nature, and must be if you're going to do it at a higher than middle-school-ish level. That's the part that's hard. That's also the part Hank doesn't go into here. He could. He just doesn't. Good physics teachers don't make physics easy. Physics is never and will never be easy. Good physics teachers make the challenge fun.
@@benjamink2398 I don't believe everything you're saying. every type of physics taught an any type of school is easy, you just need the right teacher. is what I believe. physics overall, yes very difficult. but my point was more in terms of his explanation skills rather than the actual physics of the situation. he explained it really well is what I wanted to say. some people can really twist it up for their listeners
@@aadityachavan6836 Sure. And yet physics is very complicated by its nature. Hank is correct that "You can just use the wall, and then you don't have to worry about your tires, you can just gun it". But any physics class worth its salt is going to ask you as a student to elaborate on and understand exactly *why* a wall, even with it destroying the surface of the car, can allow a car to maintain a higher speed around a turn than our best tires can. Maybe that does make intuitive sense, but physics is often counterintuitive too. So we do the math to make sure it's understood.
@@aadityachavan6836 I'm not disagreeing with you, btw. Hank is a great guy that explains things simply and well. But there's more to being a teacher than that. If you want a thorough understanding of a subject, watching RU-vid shorts on it will literally never give that to you. Ever. Even if you watched them for years on end. At some point you have to do the work, have that work checked, get feedback, do more work, and develop the understanding and skills in tandem necessary to thoroughly LEARN. It sucks, maybe, but it's true. A good physics teacher will explain things well. Yes. A good physics teacher won't be unnecessarily confusing. Yes. But a good physics teacher will make you work. Will make you uncomfortable. Will give you new, unique problems you don't know how to do at first glance and make you come to the right solution on your own. This is difficult. But it's how real learning takes place.
That's not the physics that Ross didn't understand. It was how the suspension of the car held up rather than ripping the right side off and grinding to a halt
I think his confusion is more about how his car was able to glide along the edge when normally nascar vehicles that try that, snag on the little edges of the bunkers and get bounced into a skid
Hank may have just destroyed the future of nascar in 30 seconds (or at least made one rule) Anyways super excited to hear John on the PIMA podcast, I've been listening to that podcast since week one and either of you being guests has been a dream, imagination to me. Unbelievable and what an awesome few weeks with Jane Goodall having just been a guest
The fastest way around a race track is not hugging the inside lol, that only applies to running races. The fastest way is starting on the outside at the beginning of a turn, turning in tight to the inside of the centre of the corner, and then accelerating back to the outside on the exit
didn't know about this funny nascar thing until your channel. would have been funny had i not heard of this channel at the same time learned of two awesome things at the same time.
What impresses me most is that the car has enough power to overcome that much friction AND go faster than the other cars - enough faster to beat out people on the inside of the curve.
The thing about this is there’s a balance. Racing lines are about flowing into and out of corners as smooth as possible while keeping the best balance of speed and distance as possible. Hugging the inside helps but only if you enter from the outside first, maximizing your speed and finding a way to make the best possible exit as well. It’s about maximizing your average speed.
There's also the slingshot method as well, this is when you drive behind another car avoiding wind pull and pull out behind the lead car and launch forward because you didn't have wind draft pushing your car
Escape velocity, the momentum you need to break free from gravitational pull. We use it to calculate how fast an object needs to move to temporarily breaking the bind of gravity. That wall is absorbing some of the velocity if the car and storing it in the form of heat.
I hope it’s VERY clear to everyone, chastain was at the mercy of physics the whole time. The pov that best shows just how fast he was going is from the stands… and essentially, he put the car on the wall, and LET GO of the wheel, just floored it and rode the wall. Scary shit, especially at those speeds. He’ll go down as the first and only person to ever do it in nascar
Not just that you're already "crashing into it" by already being on the outside wall, but because the radius is greater, you can take a curve faster when you're on the outside because of reduced centrifugal force. This is one reason why good trucker drivers will take the outside of a curve when taking a cloverleaf ramp onto or off of a highway, it reduces our risk of rolling over for any given speed versus taking the inside. This also applies to slick conditions, when its icy its tempting to take the inside of a curve with the thought that you have a bigger safety margin because you're farther from the outside of a curve, but in actuality you're more likely to slide out because of the tightness of the curve.
My life is a series of bouncing between the green brothers content continuously, over the span of years slowly seeing both of them here and there like a long lost cousin
Whats typically done is hugging the outside wall during the straight segments, so the cars can make as shallow of a turn as possible- they take a gentle turn so that they graze the inside wall as they go through the turn, and then return to the outside wall just as they're straightening out. The less you have to turn, the faster you can go before you spin out or destroy your tires. Watch for this the next time you watch a race, watch as the cars essentially cut the corner as much as they possibly can.
And this is why in Top Gear, Jeremy Clarkson always told the celebrities that participated in the "star in a reasonably priced car" race track lap that you need to go slower to go faster.
I really really loved the spooky Haranhall castle with Daemon pointing his sword around like a rifle. It was SO awesome and took me back to the 80's fantasy of my childhood. I was half expecting David Bowey to shimmy out with his goblin king cod piece. So Fun.
I never watched nascar but when i saw that someone was doing this i was surprised n excited that my childhood Grand Turismo strategy actually works IRL
Watching Trackmania records has taught me the best way to do it is to take the BOTH LANES as fast as possible. Taking the outside during straights and inside during turns gives you the widest turning radius possible, allowing for more speed during the turn with less risk of losing traction.
From what I've heard the best way to take a turn is to start on the outside, hit the apex on the inside, and end on the outside again. That way you're steering the least and can take it at the fastest possible speed without losing control of the car.
