Fact: Indy cars and Formula 1 cars have been able to technically drive on inverted surfaces for years. It deals with the amount of downforce the cars able capable of generating once they reach a specific speed.

Looks like Neil got into Jay Leno’s closet.

I grew up in a family of engineers and other math nerds. The only reason that we would watch NASCAR is to calculate shit like this. The physics of NASCAR is actually intense, and the amount of pressure that put on the driver's body over their careers, is far overlooked.

Neil is so good at these type of videos because he is very good at explaining things in layman’s terms, something that people in his position generally don’t do.

NASCAR is actually awesome IN person......nothing like a Muli-million dollar stadium getting rumbled like an earthquake....the noise is SO insane, you feel part of the race.

Anybody remember the "wall of death?" Motorcycles used to run inside a vertical barrel...same principle that they're discussing here...the speed of the bikes kept them stuck to the walls of the barrel

Nascar drivers drive inches from each other and occassionally make contact purposefully... That's alot of the attraction.

They only make contact in purpose in the slower ovals and the fastest ones. Around the slower ones they do it so to move the competition away, which is much needed in those ovals since they are so small that making a clean overtake is next to impossible. Around the fastest ones (Daytona & Talladega) they use it so the car in front gets a speed boost since in those ovals the NASCAR cars are air-restricted and have a lot less power. When you have so little power and are running behind someone the guy in front is cutting the air for you and it is easier to move forward, you push him so he gets faster and you can maybe even try to run away from the rest of the pack.

The comments about NASCAR being related to stock car racing are 100% true, yet they don't quite hit the nail on the head why Americans always liked NA V8s in sedans. In the late 50's, car manufacturing jobs were all the rage in the working class. The engine set up in your average car was either V8 or inline 6; a single over head cam, carburetor and a 3 speed gear box. The cheapest power gain was always to modify the engine's displacement by switching to larger crank bearings and shorter connecting rods, effectively gaining displacement for the price of piston speed. The technological progress is easily traceable with (and deeply connected to) the history of Chevy&Hot Rodding in the US. So Drag racing, the NHRA and NASCAR have always been deeply integrated communities within the car manufacturing working class culture. These cars on the race track were an extra gear, engine stroker kit, bigger carburetor fuel jets and slick tires away from the showroom floor. That was their appeal to a blue collar worker: A car he could understand in it's entirety, repair everything on the side of the road with band aids and coaxing. You may have guessed: F1 cars are almost the total opposite. Except for the designs by Bugatti from the early 40's, the amount of detail in these cars needed the professional abilities of a huge team. Bugatti built a car weighing roughly 1900 lbs = 900kg, supercharged inline 8, variable valve timing, dry sump, 4 speed, drum brake, cambered front tires (first of it's kind), 55-45 % weight distribution race car you could buy from his factory to win races and drive on the street. And those were the specs on a car from the early 40's. Mind blown first time i saw it drive and in detail. The current F1 sport's spirit is as much a mixture of it's regulatory history as it's controlled by the financially dominant teams. The infrastructures of support behind the teams vary greatly, as anyone following McLaren Honda, Toro Rosso or anyone else using Renault engines. To people unfamiliar with F1, this may seem strange: Some of the teams supply each other with engines! So Mercedes powers the Force India Team next to it's own, Ferrari powers the American Team of Eugene Haas next to it's own 'Scuderia' and the Red Bull and Toro Rosso Teams are supplied by Renault engines, which have had clear and obvious problems all season. So F1 and NASCAR's main difference is the fact F1 has jettisoned the thought of the cars being something the common man could aspire to own.

but did you learn anything?

one of the funniest 'startalk' clips.

The speed and inertia when the car first hits the turn changes dramatically because the cars weight is pressed into the turn of the road. Depending on the stiffness of the shocks some of the energy is converted into the compression. So the car will slow unless the driver applies more power to counter the energy lost through traction and overpowering the extra friction caused by the car pressing into the curve of the track. So at some point the amount of power needed to overcome the angle at maximum speed isnt worth it because your giving up agility, fuel, tire wear so that you have to pit stop more. At least I imagine so.

12:11 This is just golden

FYI, racing slicks generally have a higher coefficient than 1, depending on the compound.When they are at the proper temperature, they can almost meld to the track surface. Which is why they exceed speeds of 165 at Charlotte in the banking.

where is the full original video? i only see the podcast

I drove from Chicago to Atlanta in a marketed 36mpg car, going as much time possible behind trucks around a speed of 70mph and at the end of the trip calculated the actual mileage to be 41mpg, it comes to about 12 percent increased efficiency, or 12% gas economy.

Nascar is great and the only racing I watch simply because it is so scientific and you can use science to get ahead. Drafting and passing is like nothing else. Timing, when to do it, etc. Bump drafting you don't see anywhere else, creating a faster freight train and then breaking off. Amazing

interesting f1 fact, the spoilers can actually create more downforce than the weight of the vehicle. They could drive upsidedown at full speed.

Ha! The whole sledding conversation had me howling in laughter! XD

High velocity air flow under the car produces a pressure difference and holds the car down against the road with an effect greater than the spoilers without the drag force cased by the friction between air and the spoilers.

It really is a science. There was an F1 race there where one tire company was basically out of the running because they weren't allowed to test on certain tracks and the engineers at the tire company failed to realize that the track had been resurfaced and then diamond ground. That leave little grooves on the track. When a car turns, your tire walls slightly bend and flex.....add the grooves, and you get a surface with more bite....that made it so that certain tires were failing on the banked turn due to that little lack of track info. Racing is all about science. When you steer on a circle track, you want to come into the turn at a fast speed, then try to drive down the turn. Also, drafting and using drafting to slow an opponent so you can pass them. Drag racing, for example, some cars actually shift with such force, the clutch and transmission melts together (for lack of more intellectually accurate words), and they have to be replaced after each race.

8:08 using banking you could hypothetically set up a race where driving straight is the best way. and you could do all sorts of insane things like corkscrews.

10:25 I liked that model in the back. Would love to run a few laps in that.

I feel that nascar has two main factors for its watching. F1 has too many rules, anytime someone gets an edge or has an iffy pass, they get struck down. NASCAR practically just gives the drivers the same tools (sorta) and the drivers battle it out with allotment of contact. This makes for riskier moves, it’s tense when you see 3 wide for more than an entire lap. Another major difference is the length of turn. One turn can take up 1/4 of the track itself, that’s a ton of time that can be made or lost if you don’t have your braking accelerating spots right as well as turn in and turn out. The other main part is in person nascar would be easier to spectate as in most spots, you see all the track, vs f1 you see a small spot and just see where people are when they come by. The same issue is there for motocross vs super cross. I love f1 and knowing the tech and I find it fun to watch on tv, but seeing some guys hang 3 wide through some corners for a couple laps is awesome as well. All I’m saying is, don’t discount it unless you’ve seen it and understand some of what’s really going on.

Did he just say, “back in the day when you had rear wheel traction”.

17:20 have done this. I would drive from Edmonton to Calgary on ten bucks by drafting on a semi. Just have to stay alert, and keep your foot on the brake, because plowing into the back of a semi in a sports car is not pretty.

What and where is this place?

"And Neil drove all the way to Florida and he was only going to the store for some bread!" LOL

I love Neil's excitement.

Neil, you missed the whole dynamic vs static coefficients of friction. A tire that is not spinning (not slipping) has a much greater frictional coefficient and can provide much greater acceleration (and deceleration!) than one that is sliding / spinning out against the road surface. A fact that anyone who has driven on ice will attest when mistakenly overly applies the brakes, stops the wheels, which can practically feel like the car accelerates off the road (it doesn't, but it doesn't decelerate much). By keeping the tires turning, thereby maintaining static contact, the turn can be safely navigated at a higher velocity (within the bounds of the static coefficient, of course). The other example is 'burning doughnuts'... try not giving the wheels quite enough power to 'break them loose' from the surface and see how quickly our NASCAR driver puts it into the infield or the wall when 'celebrating' the victory with a doughnut or two! The peak velocity for the turns and 'pushing the envelope' as you were talking about all boils down to the static coefficient of friction not being exceeded... turning into a skid is all about reestablishing static contact from the low dynamic contact of the skid. Fun talk though! :)

Is there only one Mic on? I can barely hear anything and volume is all the way up 😕

Neil is actually correct about the science of the bank. I drove a car at Charlotte at a driving school. This is deceiving but the front stretch is a tr-oval. However, there is subtle banking in the tri-oval part of the front stretch. As you drive and look ahead your mind tells you that you need to steer through the tri-oval but you do not. If you hold the steering wheel straight, you will go right through the tri-oval perfectly.

One thing they didn't mention is why the tires of race cares have no tread - its because thread eliminates traction so the less tread the more traction your tires get, hence you car goes faster.

Tires are an entire subject unto themselves. Consider how they work. (my super simplified explanation :) Picture a tank or any other vehicle that uses tracks as an analogy. The tracks on a tank are really just one big heavy tire. Note that when the tank is rolling forward, the part of the tracks that it is rolling over is not moving relative to the ground. That one section, the footprint, becomes motionless relative to the ground. It has zero speed. The tank 'rides over' that section of motionless 'tread/footprint' while the rest of the track *is* in motion to come on around again. This bit is critical to traction. Each section goes from zero to X velocity and back to zero in VERY short order. Otherwise, no grip. This is the same way a rubber tire gets its grip. The 'footprint' must come to a complete stop relative to the ground while the rest must accelerate from zero to X only to have to stop once again to zero relative to the surface in order to make 'grip'. It's crazy, but that is what happens and in microseconds. Should the tires footprint fail to stop relative to the ground (failing to get a grip on things as it were), that is the exact moment when 'traction' is lost. (a spinning tire isn't gripping because of this bit of tire physics.) Now that you know this tidbit of tire physics, it only makes the idea of a tire that can hold together in the first place, let alone at racing speeds, all the more astonishing. (sorry for the long post)

Three engineers - mechanical, electrical and software - go out to lunch. On the way back to the office the car stops running and they pull over to the side of the road. The mechanical engineer insists it is something mechanical due to the nature in which it stopped running. The electrical engineer insists it's electrical as here is no other reason to explain it. The software engineer suggests they all get back in and restart the car.

Nascar used to be more attainable to get into. When anyone could build their own car and get it into a race. It has carried itself up from that late 50s early 60s standard. But if it just started as it is now, the team owners, the sponsors the money involved, it never would be near as popular. Nascar is riding on it's past appeal.

NASCAR is one of those things that gets more interesting the more you know about it. In most forms of motorsports the vehicles are very good, they're way above average of what you can buy. NASCAR does not work that way, the racecars are limited by the regulations, they are actually rather awful so that even driving around an oval is a challenge. You could buy a $100k muscle car, get some proper tyres and lap some of the NASCAR ovals FASTER than the actual racecars. The suspension, brakes and tyres anyone can buy are much better than what the NASCAR rulebook allows. It is the whole point of the rulebook, to make the cars bad and outdated so almost every oval is a proper challenge. That is why you see the drivers struggle, that is why you see so many one-car crashes and spins, that is why they just cannot avoid driving into a crash when it happens. The cars are made to have a challenging good fight, not to be the fastest. We've seen NASCAR drivers jump to places like IMSA (endurance racing) and even the Race of Champions and they can surely drive at a high level. The challenge works the other way too, drivers coming from other better series have rarely won a race (Juan Pablo Montoya had 7 wins in less than 100 F1 races and 2 wins in 250+ NASCAR Cup races).

The Coefficient of Traction for a NASCAR tire is probably considerably higher than 1... like more than 1.5. I mean: a high end sports tire pulls 1.2g on a car, with lateral load transfer, so maybe 1.3g is reasonable without load transfer, on a street tire.

actually, with regard to the more weight over the rear wheels makes it more stable is only true in a straight line, down force is free of this factor, but knowing that you know physics, if the mass is much higher in the rear the mass wants to keep moving straight, so you turn in, the front follows the wheels, and the mass in the rear wants to keep going straight, so your tail kicks out, weight balance is always a big factor in how a vehicle behaves around corners. alot of MR cars use this to their advantage, with a good driver, that weight is used to get the car to turn in tighter around corners, while keeping it on the edge of sliding. but if you take it too far, the car will be more unpredictable. there's alot of suspension design, and other factors involved in this but weight balance in general is heavier in front slower turn in but much more stable, heavier in the rear, more tail happy, a 50/50 balance keeps a quick turn in and more cornering stability

12:02 I can confirm as a NASCAR fan myself that this is why we like NASCAR lmfao

Well I hope he calculated the racing line is a straighter curve and the cars has some aerodynamic downforce. Its small but it plays a big factor in 160mph+

You talk about F1 or Nascar, while here i think dirt rally is the most fun to watch. Both live and on TV, the skills going around a corner sideways inches from trees etc.

Also, as you're banking, the normal force increases, but the Cf drops. Overall, the traction increases, but not exactly proportional to the increase in weight on the tires.

its amazing how much u can impress people with simple physics! edit: lest just say he generalized most of the calculations for the benefit of the audience

These are the simple things that matter with four wheel vehicles. I used to have an off road motorcycle and the dynamics are very different. On a dirt track with a motorcycle, even a flat one, the trick for staying with the curvature of the dirt track is to turn that rubber tire in the back into a rocket. What do I mean? The weight of a well balanced motorcycle is variable, where it is not in a car. more to the point, the traction with each wheel can be very different. Whereas a car needs to stay as flat as possible to the road surface to have maximum traction in corners a motorcycle can hang that rear wheel out with its body pointed more into the center of the curve and the motorcycle rear wheel can spit out a lot of dirt at an angle to the direction of travel to help it stay within the boundaries of the course beyond ordinary traction. It doesn't hurt that the competition gets to eat that dirt either.

I'm curious about the g-forces drivers would experience on the 31-degree bank while going 200 mph.Could that be a reason there are no 31-degree banks?

Hay Tab, thank you. Just thank you.

Build a track with a corkscrew shortcut. The drivers would have a choice of the shortcut or a much longer normal track bypass. Make it through the corkscrew and you jump ahead.

They do over 175 at Charlotte on exit at the slowest lol. Average speed record without pits/cautions is 183 also

Neil deGrasse Tyson schooled these guys, respect to all

I don’t want to argue with an astrophysicist, but I have driven that track in my 200 HP car. First, my car topped out around 120mph in the turns, 45mph slower than your calculations. My argument is, you said the car would turn itself at 200mph on a 31* bank. But my car never turned itself on the 25* bank going 45mph slower than your top speed for that bank, and I was never pulled to the bottom of the bank despite going slow. I have video, and you can see me clearly turning into and throughout the turn.

The jokes are nice!

This is what I learn in freshman physics and these old guys are like woah!!

What if a car is in about a 10 degree drift and the load on the rear tires is greater, would you be able to go faster and accelerate faster?

Honestly, I never had interest in NASCAR or Formula1, but after hearing this I have more respect for the people and machines involved in it.

Could someone tell me how he calculated the top speed of the turns

Thoughts on top fuel dragsters????

I could watch ndgt sit next to dubya in the commentary booth throwing out some physics while they race.

The car couldn't take the turn without steering input, regardless of bank, because the car could never consistently hit the exact velocity needed, and maintain it through the arc, over 500 miles. Changing weight, tire degradation, and aero change, etc. He's generally right, but there's some stuff he's glossing over for the sake of simplicity

If you pass a little bank with a determinate speed actually the bank turn your wheels into the corner alone but obviously in a certain speed if you pass that speed are you going to do off road.

with downforce you could maintai 1 of fcoeff so you start at 9.8 but little by little accelerate

Spoilers actually don't increase a cars mass (because that would be impossible un less you add parts) but they do increase relative weight, which affects the driving characteristics of a car (except moment conservation) making it behave as if it was indeed heavier, Ventury tunnels however, rely on vacuum to create a downward (relative to the car) force vector that increases traction but doesn't increase its relative weight, so ventury tunnels are much more efficient that spoilers.

NASCAR cars are more relate-able if you work on your own -- just recently adopting fuel injection -- they are way behind street cars in engine technology. And they go 200 mph. That's interesting. I enjoy watching either NASCAR or F1. But I do get frustrated that if the tire lettering of an F1 car touches the tire lettering of another, most likely they are done for the day. The sheer robustness of the NASCAR cars makes for better entertainment for my time-limited budget.

why the hell people place quite videos...have to turn up volume a lot.

15:28 This is one of the funniest things i’ve ever seen. His mind was blown on the simplest thing. Your 45/50 some old and you discover downforce for the first time?

You also have to figure out tire compounds, psi, heat etc

of course more weight on the rear wheels of a rear wheel drive vehicle gives you better traction. this is why people keep heavy bags of salt or sand in their trunk. the weight gives you more traction, and if you do get stuck, just throw some underneath your tires. 👌

165mph, I'm wondering if tire size or contact patch is a variable in traction? Do drag racing cars accelerate at more than 1G? Surely a nascar with donut spare tires would slide off the track in the bank, but an F1 car could take that turn easily. Unless we aren't thinking about down force generated? I get the calculation, I'm just sceptical that all variables were considered... then again it's 2am...

That last joke was hilarious xD

so despite the downward pressure caused from the air flow around the car, a car cannot accelerate above the acceleration of gravity? i suppose that the acceleration limit would be gravity when the car is at zero mph, but when the car is at 60 or more, despite the fact that it is harder to accelerate due to air resistance, there should be a higher acceleration limit, right?

5hredder exactly. However, drag exists and you have to push through air which has mass itself.

I met a big shot engineer from Bell Helicopter who was definitely smarter than I am but was absolutely convinced that it was impossible for a car to accelerate at 1G or more regardless of the type of tire. He even “proved” it on paper with equations. Then I showed him a video of a top fuel dragster reaching 500 km/hr in under 5 seconds. End of conversation. So-called engineers who are not into racing don’t have a clue about the capabilities of modern race cars.

Who is the woman eating in the background, behind Neil

What you talkin bout Neil? First of all the coefficient of friction on racing slicks is waaay higher than 1. Consequently tires and other rubber things suffer from a property called viscoelasticity. As the weight on the tire increases its coefficient of friction actually decreases. Of course the grip will still be highest on the tire with the most load, however when you take cornering forces into account things get more complicated. Centripetal force increases perfectly 1:1 as mass increases, however due to viscoelasticity grip proportional to the centripetal force actually decreases. Chuck, if you were to actually fill your trunk with bodies you would be shifting the weight of the car to the rear tires decreasing the grip from the rear tires compared to those of the front. If your weight balance goes much past 50:50 you will find yourself in a puddle of brutal snap oversteer, the definition of instability. The main reason why a rear wing or spoiler improves stability is because of the drag it creates, like the fletching of an arrow. You can adjust this aero balance to change the cars tendencies toward oversteer or understeer. A stable system will see the center of pressure (most of the drag) behind the center of mass.

All of these people saying he's wrong and should study up but do they not realize that he is an astrophysicist? I don't expect him to know everything about NASCAR. I just like hearing him talk

FWIW speed isnt the major factor in going upside down with a vehicle, it is the downforce generated by said speed, the bodywork/floor of the vehicle, and the weight of the vehicle itself. If the downforce is greater than the weight of the vehicle, upside down driving is 100% possible at that speed.

He's not quite right about the max. coefficient but he got on the right track with the interlocking track. Tires deform and bite into the surface, so, on a slightly coarse track, a car could theoretically accelerate faster than acceleration due to gravity.

I think it was mythbusters who did a controlled experiment on drafting and that it would increase your fuel efficiency by about 20+ % depending on close you got to the truck. A significant but not overly massive increase.

Those two make the best duo lol

I could watch NDGT talk about cars all day! As for why NASCAR is more popular in the US, i think its 1: We invented it. 2: Its in a stadium! And i think we invented that too. Because the track is in a circle you can see the whole race happen right in front of you. With road courses you only see the cars for a few seconds, then they make a turn and they are gone. Racing in a circle is just better when your actually there. Plus the infield of the stadium makes a great place for a tailgate party. Southerners love a good tailgate BBQ.

7:45 but how many gs would they pull? because based on this idea of track design you could design a track that is only limited by g-force and blackout limits. lol, g-suits with advertisements on them, i can already see it.

I think NASCAR is more popular in America simply because of the cultural history (bootleggers modifying their cars to run from the police) which started NASCAR racing, and the subsequent generations of people who grew up watching it. Otherwise Formula 1 is surely more interesting in almost any regard

Andrew Clark yep. Has nothing to do with language. It’s the roots of how NASCAR was formed.

Well there is that but also any teenager can make his car look like a NASCAR race car but you can't make it look like a Formula 1 car. That makes a connection that is unbeatable. I started my life as a racing fan watching Indy cars until I saw my first NASCAR race and thought "this is better because their cars look like the ones I see on the road every day".

Thank you for explaining that. I had virtually no regard.. no, strike that, I had absolutely no regard for NASCAR until you shared that history. Kinda reminds me of how Clyde Barrow stole 8 cylinder cars and used BAR weapons and virtually out-ran and out-gunned most of the local police until Frank Hamer, the Texas Ranger out gunned him - and tricked him rather than out-run him - which they couldn't before, so i guess same thing w/ the bootleggers trying to outrun the police. NASCAR is more interesting to me now. Formula 1 for some reason always naturally did. Thanks for sharing that! 😄

True especially if you grow up driving Chevy and Ford it would be fun to try and replicate what the pros do which is nearly impossible to do the same thing with formula 1
