*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.
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 )
Liquids are *considered* incompressible is more accurate. We all know that they are in reality slightly compressible. Great video, very instructive, love it !
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...
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.
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
Yeah as someone who just got into F1 (although I use to watch it as a kid during the early 90's but with no real clue) these vids helped a lot. I actually enjoy F1 a lot more now and follow it religiously. The channel had a huge impact on that.
I had no idea on the technical aspect of F1 until I came across your channel. You make it so simple and helpful to a person who wants to know about the technical bits of F1. You also make it sound so simple which if your talent. Keep up the great work Stuart.
The level of details, information and analysis you put in these videos is just impressive. Definitely the best F1-related channel on youtube! Keep up the awesome work!
Your video on crash barriers and its uses was excellently demonstrated in this this last weeks Canadian GP. Hartley "slid" off the hard wall surface and Stroll was "absorbed" by the crash barriers at the end of the run off. Two very different yet effective barrier systems.
Finally caught up to your videos. Have watched every single one. This is the first one I've caught as a subscriber. Great work on these, they really show how advanced F1 engineering is.
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.
@@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.
What an awesome, and concise explanation. Please do some more Stuart. It's so nice to finally understand the 'big secrets' involved with F1 advances. If you can educate us with a similar video for each subsystem, e.e, steering, suspension, transmission, body aerodynamics, materials etc, that would be amazing.
As a student of Automotive Engineering, I reallly liked how you managed to discuss brake bias effectively without much numbers or proper graphs, that takes some serious skill haha, keep up the good work !!!!
Been watching you for a couple years, and the videos maintain that unique style you have, but are improving quality wise greatly. Also you're a great teacher at explaining F1 in general. Thanks for the video, I never quite understood why Ricciardo's brakes were overheating. Now I do.
Absolutely LOVE the videos Stuart! This is my favorite channel on TH-cam and I check daily to see if you've posted yet another zinger. Every video you make makes me appreciate and love F1 even more! Keep up the great work mate!
these are thing's you can really understand (in) after an engineering degree. You learn the principles behind this in mechanical engineering automotive or mechatronic named course of study. Until then you can enjoy these videos and keep the maths for later xD
I'm from Mexico and i really love your videos!. There isn't a channel like yours in spanish but one of my favorite things about F1 is the technical complexity and with your videos I understand everything!
Man, this is so informative and well put together! At first I was like "damn, 11 minutes talking about brakes...", but by the end I went like "what?? why is it finished already?!"
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.
Reasons why I got into F1 is how much engineering are put into these cars it's very interesting, thanks for making simplified versions of these I know its much more complicated than that but it gives some basic understanding of how they work and I don't have to watch a 30 min documentaries of it lol.
I love that you use animations rather than a plain whiteboard ( *cough cough Engineering Explained* ) it's so much more engaging with us as the audience.
2:45 Interesting fact, Carbon-carbon is the material used on the underside of the Space Shuttle (the black tiles on the bottom), which withstand the friction of atmospheric entry. ...so you know they mean business!
Great video as always! Wondering if it could be possible to do a video on car rake and the various advantages and disadvantages you from setting up high or low rake cars?
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 :)
If you don't have 1 million subs by next year, you will have been robbed. These videos are incredible. Concise, detailed and amazingly well researched. Well done
Another excellent video. You without a shadow of a doubt make theoretically complicated auto technologies realistically simple. Not an easy thing to do but you pull it off 👏👏👏👏👏👏
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!
2 things: #1 These videos are awesome. Keep them up. #2 My 3 year old falls asleep to these videos almost every night. They just seem to make her pass out.
Thank you for your videos. For someone who has very limited knowledge about Motorsports, your videos are always insightful about the finer points. My best to you and yours sir.
A great topic you could cover in the future is talking about the drivers themselves, what they physically need to become one, and the truth about paydrivers, contracts and all that shady stuff in between. Great content as always!
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.
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.

- 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.
i think there's a spoonerism in the mgu-k section
Chain Bear F1 is there ABS ON F1 CARS
Enrique F No as that would be considered a driver aid hence why you see people locking up. ABS would stop that from happening.
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 )

Drivers can adjust the brake bias during race between the corners
Only when the brakes are not being pressed at the moment
Great explaination! Please do one on how the MGU-K harvests kinetic energy because right now this seems like 100% magic to me

@@andrewb378 it's just an electric generator attached to the turbo shaft as far as I know.
@@andrewb378 That sounds more like how the MGU-H (which gathers energy from waste heat) would work.
@@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)
