F1 Braking Systems

[@chainbear]

*CORRECTIONS CORNER*: - I say "fluids" are incompressible but what I meant to say was "liquids" are incompressible as "fluids" includes liquids and gases (and some other matter states). Because my brain was saying "brake fluid" I accidentally used the word fluid instead of liquid.

[@davidlerer5680]

i think there's a spoonerism in the mgu-k section

[@enriquuu]

Chain Bear F1 is there ABS ON F1 CARS

[@josesammut9396]

Enrique F No as that would be considered a driver aid hence why you see people locking up. ABS would stop that from happening.

[@jonascaes1085]

I'm sorry to inform you that even your correction is wrong. Liquids are compressible even more then you might think. A liquid like water will compress 10x easier than concrete and even 100x more then steel. (elastic modulus of water EV = 2.10^9 N/m2 )

[@6735B1]

Liquids are *considered* incompressible is more accurate. We all know that they are in reality slightly compressible. Great video, very instructive, love it !

[@oinka720]

Wow technology has progressed quickly. I can remember in the early years of f1 when the brake discs were pinched by real live clams. So when you wanted to slow the car you would yell at the clam and he would use his shell to pinch the disc. We called it "clamming on the brakes". Then they improved it so that instead of yelling at the clam, you would push a lever that struck a flint and lit a fire under him. We called that "brake by fire". And later on came the invention of having aquatic birds in there to blow air on the clams and those were "cooling ducks". Goggles Pizano won 11 races that year. Those were the days...

[@JontysCorner]

An interesting side note to this is that as technology of road cars progressed without the competitive rules of F1, various forms of cooling were attempted for brakes with liquid cooling proving very effective when using melted butter; this in turn caused the term 'getting on the anchors' to become popular.

[@robkitchen5344]

And i thought they would roll a boulder from the side of the track in an attemt to "break" the car..... But you could imagine this would slowly stop the car if the boulder missed and another attempt had to be made... The factory sponsored F1 team , having more resources eliminated all other teams when they set up series of "breaking points" on the chassis and along the track with "break men " would have to "breakfast" for the first time

[@Asasnol21]

Great explaination! Please do one on how the MGU-K harvests kinetic energy because right now this seems like 100% magic to me

[@andrewb378]

I'm not an expert on anything F1 at all but if I had to guess, I would say that it probably uses a thermoelectric generator of some kind. These are kind of like thermocouples but a bunch of them strung together. If you want to learn more about them, check out this whole webpage about them. powerpractical.com/pages/how-do-thermoelectrics-work You could use the heat of the brakes paired with the cold air rushing by to create a very strong temperature differential to create quite a bit of energy which you could put back into batteries or the like. However, because the video talks about the MGU-K actually doing some of the braking, I would guess this isn't how they do it in F1 because thermoelectric generators are a much more passive process than that would suggest. It's fun physics either way though.

[@Argosh]

@@andrewb378 it's just an electric generator attached to the turbo shaft as far as I know.

[@exscape]

@@andrewb378 That sounds more like how the MGU-H (which gathers energy from waste heat) would work.

[@jacobgross319]

@@exscape if the mgu-h was powered by the turbo SHAFT then it would be harvesting kinetic energy not heat, making it an mgu-k (i believe lol)

[@exscape]

@@jacobgross319 I sort of agree, but that seems to be how it works. Every source I find either states that, or some less concrete version that doesn't actually mention the details.

[@advaitrao]

Was a very detailed description. Thank you for the very well curated content. Just one thing I'd like to point out, which is a suggestion and by no means criticism! Friction coefficient is not a property of a single material, but always a property of combination of materials/surfaces. For ex. rubber on ice and rubber on asphalt will exhibit very different properties. This can't obviously mean that rubber has two different friction coefficient values. Therefore you always specify friction coefficient between two surfaces :)

[@perpetual_bias]

[@HeizoelWalther]

Great video, though it would have been interesting to see how the MGU-K transforms kinetic energy into power for the battery. Also the brakes are a big factor in heating up the tires. Otherwise very informative video! :) Keep up the good work.

[@plasterbrick2011]

3:13 Also, ice is tecknically not slidey. Its just a thin layer of water that is oroduced when pressure is applied to it which makes it seem slidey. If you try to slide on ice in sufficiently cold weather, its surprisingly grippy

[@ArtiQormemeti]

It would be great if you could get into more detail about how the MGU-K actually uses the braking energy. Other than that, fantastic job!

[@immikeurnot]

Seems pretty simple. MGU means "motor/generator unit" (practically, there's very little difference between a motor and a generator, so it's trivial to make something that can do both) and the "K" is for "kinetic." It's going to work just like a hybrid road car - you step on the brakes, the ECU increases field at the MGU, causing it to start charging the battery pack. Depending on all the variables mentioned in this video, the field strength will be regulated by the ECU. It's hard for some people to understand (looking at you, all the "green gas" and "HHO" idiots from a few years back), but increasing electrical load on a generator increases the mechanical input that's required to turn it because physics. This is the reason older cars with loose/worn belts would get extreme belt squeal when they were first started - the generator (AKA alternator - same shit, different way of getting it done) needed more energy input to recharge the what the battery had lost from sitting and then from the high amperage drain of cranking the engine. After a few seconds, the squeal would usually stop. So, long story short, the MGU-K is going to help slow the car by taking the kinetic energy of the car and instead of turning it all to heat (a lot of it will be lost as heat, though, because thermodynamics), it's going to convert it to electricity to be stored in the hybrid battery. If you wanted to, you could actually assist the mechanical brakes with a generator, a heating element and some kind of heat exchanger.

[@leaf344]

Great channel and great episode. Typically when I seen a piston in a hydraulic system the mechanical advantage comes from a smaller piston (the input or foot on the pedal) being compressed at longer stroke while the output force being being larger than input, but the output stroke (ie linear distance traveled) smaller. Just a small detail. Also, it is alright to assume fluids are incomprehensible. Most people state it’s a compressible when it’s a gas.

[@rohanc.philip1886]

Your videos are outstanding! The level of detail you introduce really helps me develop an even greater admiration for the sport. Cheers, and keep up the brilliant work!

[@emperorcaesarandyvsrex]

Fluids are not necessarily liquids, but also gasses (and plasmas) too. While it is hard to compress a liquid, I can assure you that compressing a gas is trivial. It is important not to get confused between a liquid (the state of matter) and a fluid (anything that has the capacity to flow) as you have done in this video.

[@chainbear]

ah yes this is true - careless language

[@keastie6671]

I was thinking the same but most of the time in everyday life, these two terms are interchangeable so a simple video on youtube should be fine to use them in this way.

[@chainbear]

I would normally argue that in every day language it's fine but I do specifically talk about the difference between liquid and gad compressibility so that's a boo-boo on my part
