This is a much better way of learning about understeer and oversteer than my method of being a twit until you end up in a hedge.

Yay, Chain Bear is back! WRT rallying vs F1: All tyres require a certain slip angle to generate (peak) side force; Rally tires/tyres on a loose surface generate peak grip at MUCH larger slip angles than a slick on tarmac. Plus aerodynamics work terribly when the airflow isn't from the front, so getting an F1 car sideways kills the downforce. That's most of it really. No mention of weight transfer? Might open a can of worms, but kinda important in consideration of over/understeer.

FWIW Stiffness of suspension affects how fast the weight transfers rather than whether it does; magnitude of acceleration and centre of gravity height how much it does. True that they have wings and plenty of downforce, but then they brake harder than anything most folks ever get near. For an otherwise balanced car it will still massively effect the understeer/oversteer balance if you trail the brakes through turn in (for instance). Not driven one myself obvs, but it's still physics (and you'll find references in driver autobiogs too..)

Did in need to know what oversteer and understeer is? No. Did I still watch this video because I love Chain Bear? Yes, of course I bloody did!!

Glad to have you back! Hope you’re feeling better!

Understeer is when you hit the wall with the front of the car, oversteer is when you hit the wall with the back of the car.

Great to have you back! Just to deepen a bit on the subject (based on my limited sim-racing experience), when talking oversteer and understeer there's a difference between turn-in and exiting the corner. On turn-in you're typically braking and thus decelerating, which transfers weight to the front and if the front suspension is too tightly set up (esp. compared to the rear) the front wheels will start sliding and you have understeer. If the front is too soft compared to the rear, the front will happily turn in while the rear looses grip and starts sliding into an oversteer. When exiting a corner you accelerate so you want as much rear grip as possible (on rear wheel cars like in F1). If the rear suspension is too tight you get wheel spin (esp. on F1 cars with about 1000 HP) which will introduce oversteer. If it's too soft (compared to the front) on a high power car it might start sliding on the front wheels introducing understeer. This relationship between the front and the rear is usually what drivers talk about when they mention the 'balance' of the car.

Very nice video CB. There's a tricky thing to remember about oversteer, particularly in F1 cars. So, you've applied too much throttle and now you're oversteering. Reducing throttle is the primary remediation, true, but when you reduce throttle, the weight balance tends to shift forward, taking weight off the rear tires...causing more oversteer. This is called "Lift off oversteer" and it's why you have quotes from rally guys like McRae saying "When in doubt, flat out" (because lifting is also dangerous). To further exacerbate this issue in F1 cars, since the aerodynamic effectiveness of the wings is only present for certain attack angles, if you exceed that angle (by, say, oversteering), the car immediately loses all downforce, essentially pitching it entirely out of control, which is why it is rare and notable when an F1 car is saved from a big rear slide.

I've heard that rally cars also slide to clear the loose topsoil and get to more solid ground.

Glad ur back man love the vids!!

And then there is 4 wheel slide which used to happen in olden olden days of F1 :D

@jubuttib

Technically (and I do mean "technically") it still does. All tyres, whether they be on tarmac, dirt or ice, will generate maximum grip at some amount of slip. How much slip is needed for maximum grip depends on a massive variety of things (tyre construction, rubber type, tread patterns, tyre temperature, momentary load on the tyre, track material... It's nearly an infinite amount of things that have an effect, and then you factor in that tyres produce grip through multiple different methods at the same time, all of which can react differently to changes in the other things), but if you're cornering, braking or accelerating, your tyres are sliding, at least a bit. In the olden days of F1 maximum grip tended to happen at significantly higher slip angles than these days (rubber type, tyre construction, tread patterns, lack of downforce were the primary reasons), so going around a corner while sliding at a 10-15 degree angle was just the fastest way, if you could keep things under control. With modern tyres, and especially aerodynamics, which tend to drop REALLY fast when you start getting sideways, the peak cornering forces might occur at 4-8 degrees, which is really hard to see from the outside, and makes the cars look like they're on rails, but the drivers can definitely feel it.

5:53 loved the short technical explanation on the scandinavian flick there, i'd like for you to touch more on rally topics, even if you're more knoledgeable on f1 and track racing, would like to see the input of someone that with a more technical opinion of racing, speaking on one that relies heavily on instinct.

Cars in GT sport do both of these in the same time....

You deserve a mil subs!

Unsealed roads are also granular surfaces so as the rally car's tyres slide against the surface, it causes the stones or other aggregate to bunch up and pile around the tyre as it digs in. Produces a reaction force against the tyre. This might be why more slip angle can be controlled in rally.

Unrelated question, but still. Some circuits are universally agreed to be very boring because of small number of overtakes. Why can’t we just increase their width in several places to fix it? (Not in Monaco of course, but in France for example.) Will that have some drawbacks? Thanks for your great work!

Not being able to overtake is usually not a factor of the overtaking car running out of track. Getting alongside in the first place is the problem. Slipstreaming and/or getting a better exit onto a straight usually facilitate that but in modern F1 not so much. kzread.info/dash/bejne/a6Z-w7WmhKS_ldY.html

Often is is not how wide or narrow the track itself is. It is more the type of corners and their combination which doesn't allow to get close and in an overtaking position. As long as the first car sticks to the ideal racing line, you will have a heally bad time overtaking. But this really would make a nice video, as there are lots of aspects. Some corners and combinations allow for different lines and can mak ean opportunity to overtake for example. A simple 90 degree corner doesnt have that, it just has one, boring, line which is fastest.

@dertodestoaster1509

Many of the super boring tracks in terms of overtaking are the high downforce ones (I.e. Russia, Singapore, Spain, etc.). So often the underlying problem in those places is dirty air, not the track width. Your idea might work for very specific locations though. Right now I’m thinking about Hungary, enabling more lines in the last three corners could maybe improve racing.

Welcome back chain bear.

This animations are incredible

One important aspect not discussed here is that tires, instead of following 2 levels of traction, one for rolling and one for sliding, actually have a smooth transition from one to another. If it weren't that way, cars would fly off corners pretty abruptly whenever the limit was surpassed. There is a test where the vertical load is mantained constant and the slip angle (between tire direction and direction of travel) is varied. The side thrust is not linear with the angle, and that is what kinematically, makes the car go seb vettel.

Welcome back from your time off. And thanks for answering a question I've been low-key wondering about: why isn't there intentional oversteering in F1?

Hope your health is all better!

Good to have ya back mate dont go overdoing it

Little late on this video, but an excellent choice to take time off for yourself Stuart. Hope you’ll be able to keep making these fantastisc videos :D

I thaught I already knew What it was but you always add some knowledge to my concept

3:23 Slight extension to the subject matter there, there is a significant difference between going too fast and lacking the overall grip to make the turn at that speed, and having an understeery car that just doesn't want to turn in properly. Understeer and oversteer are primarily an issue of grip balance between the front and the rear end. If your front end runs out of grip first, you understeer. If your rear end runs out of grip first, you oversteer. You can adjust the setup of the car or possibly change your driving technique to overcome these two. If both front and rear run out of grip at the same time, you don't over- or understeer as such, but you still won't make the corner. Unless both your front and rear are setup poorly, and just adding downforce isn't an option either, there's not really anything you can do to overcome this issue, other than slowing down more on entry.

Great video. Noted and going to be implemented in Motorsport Manager :)

Please do a video on dry and wet racing lines

Lifting off to correct oversteer is most often bad advice. It will result in the weight of the car moving forwards, which decreases the traction in the rear even more, making the likelyhood of spinning out much bigger. The phenomenon is called lift-off oversteer. What should be done instead, is keeping the throttle roughly constant while correcting the slide with steering.

Thanks for the video. I hope your health is much improved Stuart and that 2020 is a great year for you.

My dad always asks me what understeer and oversteer is. I know what it is since I've played racing games and gone karting. Its hard to describe to someone who hasn't played a racing game or raced cars.

Welcome back!

Almost right about rally cars. There's no point sliding a corner on slicks. The reason they use their accelerative force to take a corner (as in oversteer) is because their lateral (sideways) traction is worse than their longitudinal traction (forwards and back) because the tread patterns are aligned this way. In rally, acceleration and deceleration is king so you use that acceleration to also corner fast. Another point about rally is as you say, the road surface is often quite slick. You simply cannot rely on the track surface to give you the grip you need. Instead of trying to dig further into the track to find grip, you can actually use the track as your acceleration media. Think rockets here. F = ma. Rally cars actually shoot off loose bits of track behind them as they accelerate and every action has an equal and opposite reaction. The bits you throw out the back pushes the vehicle forwards. Thus, when cornering on a loose bit of surface you want to throw the loose stuff out behind you and the consequence of this is that you also find a more solid surface to gain traction on underneath. So yes, they use their forward force to drive the corner but they don't do it just "because", they do it because that's their optimal strategy for finding traction on those surfaces. Another thing they tend to do is cut corners, dipping one of their front wheels into a rut or ditch to guide the car around a corner like it's on rails. If you listen to pacenotes you will often hear "don't cut" and that's because normally rally drivers want to dip their wheels into the inside of the corner to gain this "on rails" effect but some corners have large rocks or other obstacles that would damage the vehicle if it went into it.

Beautiful explanation. Hope you're in better health m8

Street cars can either understeer or oversteer depending on how you drive them and shift weight forward or backward. F1 cars have aero balance to consider; how does the front to rear wing ratio change with speed, and would drivers want oversteer on slow sharp corners but want understeer on faster gentle (or banked) corners ?

Welcome back :)

Can you explain about how tyres work in the next video? Like what happens when tyres get more weight on them or when the tyre gets an angle relative to the ground. Also I wonder why large tyre contact patch brings more grip while other objects such as bricks maintain almost the same friction regardless of its’ size of the contact surface
