My name is Bond, Van Der Waals Bond.
which is the weakest bond😂
Ohh man😂😂👍
@@itsanoynomous3253 It way be the weakest, but I think it's kinda the coolest
My name is Bond , James Bond
covalent bond is looking for you 😉😉😉
There’s also additional consideration for how the slip graph changes when on snow, ice, and gravel that is very interesting!
Enriched study is there covering your curiosity. But seems to be only for professional
this is why abs can actually elongate your braking distance in snow.
the graph just shifts downwards, starting from dry asphalt - gravel - water/rain - mud - ice with ice having a coefficient of friction as low as 0.1
@@n_u001 well, not always but it depends on how strict or agressive the ABS algorithm is adjusted
This is like Engineering Explained but with 3D models and it's amazing
Engineering Explained went Hollywood now. He isn't the same just like Vehicle Virgins!
This is very important to know if you want to get the maximum performance out of your car when time-attacking. This is also why you are much faster around a corner when you are auto-rotating (the zone where you're not quite powersliding, but also not completely gripping up).
I like the cadence of presentation here. It appears to follow that of decades-old informative videos, and for good reason, it's easy to follow. No exaggerated dramatic effects. It is rather technical though, which is okay, and we can rewind parts of it to help us gain clarity.
Well done.
I always get more confused after watching these.
SAME FOR ME
These videos are actually about solid mechanics's module in university
You would perfectly understand the video if you have took the cours
You can find it on youtube by the way
Just type mechanic of solid lesson
@@hichamismailialaoui6870 so basically we need slip for friction to cause the adhesion region which means TRACTION?
@@burntnugget1854 Traction is the ability of a tire to remain in contact with the ground. Friction on the other hand counters the movement of the tire (translatory movement for example). Slip on the other hand is caused due to adhesion which on the other side is a result due to van der walls bonds. Just to make it more undersandable, traction and slip are two ends of a mangnet. When there is more traction, there is low slip and vice versa. To make it even more visual imaginable consider two gears. When they mesh together properly, we call it more traction. However, when are not able to fully engage but slides over each other it is slip. The same goes with the tires.
@@diggaseileise1302 wow thankyou for that detailed explanation ❤ very helpful
Watching these educational animation videos takes me back to grade school. Love it!
coincidence, I am doing belt slipping now in the Component Design course
To get a better understanding about this topic please watch this video - ruclips.net/video/y5Y-w4zGW00/видео.html (Kyle Engineers)
Another video to understand another video
Informative...
The more I watched this video the more confused I became
@@God-eu7tp I detect, yes indeed.
Same
The less you know to know.
The more I watch this the more I'm sliping away......
I loves these informative video, I get to learn something new.
Thank you for a great video again :-)
I would just suggest a small correction: The vehicle velocity in an ABS event is not determined by a Radar. I mean we have ABS in the cars since the 80s while Radar is a technology making it's move into the car world now. Additionally where should the Radar get a reading from if there are no fixed objects in the vicinity.
Instead the car is using algorithm to approximate the actual speed. During the ABS deceleration the vehicle obviously does not know the allowable slip either as this various with road surface. So it will steadily increase brake pressure to an individual wheel until it manages it to stop it from rotating. It backs of the pressure then immediately and consequently starts to steadily ramp it up again. In the phases of very little brake pressure the vehicle gets an accurate estimation of how fast the car is actually going.
I did my MS on traction control. They missed that there is also the deformation of tire when accelerating in a straight line. Basically your maximum acceleration is when there is some slip (operating at the peak of the curve). When on ice the curve is flatter with a more abrupt change on the downslope side of the curve. Can also use accelerometers to get velocity by integrating.
This is modern education with 3D visuals used to their full potential. You fall right into the ranks of 3Blue1Brown and Eugene Khutoryansky. Bravo.
Yeah
Thanks for the simple yet precise explanation of Slip. Im an automotive engineer and I can tell you slip is a very complex phenomenon
This is not how a tyre works and the slip angle does not produce force because the contact patch is slipping. Please be careful to not spread inaccurate information about such a complex thing as a tyre, it is hard enough already to get actually precise information about this topic already. The slip angle is a way to measure longitudinal deformation on the tyre. As you said it can be calculated as the ratio of the velocities. The force is originated because for example if the tyre is rotating faster than the road bellow (assuming that the contact patch is stationary in the ground) the rubber is deforming and accumulating energy that produces an elastic force to restore the rubber original shape. This is easy to understand when you look at a dragster tyre in slow motion. Most of what is said in the video is not what really happens but instead a way to simplify the thought and physics of a tyre
While i'm sure you are 100% correct, I'll just say that people don't generally listen to or acknowledge an opinion when written with language like "pretty terrible explanation" or "please inform yourself". You can say whatever you want, however you want but, all i'm saying is, don't be an asshole if you wish to inform others and expect them to listen ,a little humility would serve you well :)
@@vrai3078 Fair... edited. Simply annoying to see the amount of misinformation on this topic. Slip angle and slip ratio is simply a measurement used in some mathematical models of a tyre to relate behaviour with something measurable. So explaining that they cause the behaviour is like saying clouds in the sky means rain. Sure it is related but not the cause of it directly
Thank you for this comment. I was so confused because i just found out about pacejka formula and this video basically goes against it
Zero slip means wheel is free Rolling, there is allways little bit slip when accelerating, braking or turning, this is why tires do wear over time. Tires just slips so less that you wont notice it.
I have a BMW that is very similar to that. It is a 4 wheel X drive. When I have the anti-skid function turned on, it does not slip much, on dry pavement or even on snow. The other day, I went to a big parking lot that had snow on it. I gave it a lot of throttle and car did not slide out of control. The engine reduced the gas and individual brakes were working to keep the slipping tire from slipping out of control faster than the other tires.
When I pushed the button and stopped the slide control, it went out of control and slid all over the place. It is amazing technology.
Yep its great stuff.
This is weird, youtube literally suggested a video of this yesterday to me, except it was a video from Years ago. And Learn Engineering put this out today.
same here XD
I got that video like 5 minutes ago :D
ya'll should buckle down in class, work hard, get knowledge, demonstrate your capacity... RUclips thinks you're smart...
first thought it too but then I saw the new BMW Model and it couldnt be that old
Best car educational videos, keep up the good work. Thank you. 🚗👍
Yeah this makes perfect sense to me. I was unsure how this worked, but this video explained it perfectly. If you taken a college physics class this explanation should make sense to you.
We need more of this series!!! I NEED MORE!! MY TEAM NEEDS MORE!!!
This is the best channel on youtube
Keep doing these type of videos love from 🇮🇳
wow this video pop up to my notification bar in my phone and its relevant because im playing car parking simulation game and im struggling to park my pick up with trailer because of slippery tires. 😂 and i don't even know whats going on in this video, but that's coincidence, just for the sake of my problem i watched it and also because i click notification bell of this channel. 🙂😂😂
Wow seriously very good explanation of each and every simple and important topic
Another high quality content for absolutely free
Good video... waiting for part 2 on slip in case of cornering
you made a glory .... this series is very interesting .... we wait for more
OH my GOODNESS this is entertaining to watch. The racing driver and the automotive engineer within me are both bubbling with satisfaction watching this.
Nice images, superb narrating voice, great animation... but I didn't understand anything.
It would be good if you put citations in the description or a pinned comment. You say researchers are conflicted on the location of the slip, I would like to see the research on this
my master thesis is related to this topic. The part of the graph shown in the video is only for traction, well some researchers have proven that this is not the full graph, as there is another part for braking. You should know that the car behaves differently while tested in traction or in braking modes.
Thank you sir for providing quality free education
Geat job..informative. It helps to understand more concepts..please keep up good work. Thank u
Thanks for your free education!
Please keep this channel. I appreciate it.
Best video 👍 for understanding the Friction
Which of your videos explains more in detailed and more aspects about slip angle?
Thank you for an in-depth presentation, well explained.
Want more videos on tyre dynamics... waiting for it
4:09. I swear, some Toyota products aim close to that 8% slip. Such sensitive ABS system tuning.
Great I'm Waiting For This....
Yes. It is wintertime. Thanks youtube suggestion...
Who ever made this video must be a genius
Very detailed and accurate information. Also ultra realistic 3d model. It's superb sir.
Love your videos.
For the case of block on the table at 3:14, is it the same to say, that the so-called "static friction" force doesn't exist at all, and friction only exists when there are relative sliding on the contact surface?
Also weird to think that during powered driving, the perimeter of your tyres are always moving faster than the road your driving on.
But only ever so slightly. I can't back up this claim as I haven't studied the material well enough, but I expect that under normal driving conditions in a straight line the tyre slip is below 1%.
Amazing video. Thank you.
Very much appreciated brother
Thank you for the informative content, waiting for the 3rd video of this serie, please make it quick :)
Please mooore vehicle dynamics pls pls!
Very nice explained, well done
How you make these beautiful animations? Which tool(s) you use?
You are rocking and fabulous
Thanks for wonderful and interesting
Video .
What software do you use to make the animation look so good?
I never really questioned it but now that I think about it: What does x% slip even mean? Like isn't it just like block on the table? You either don't move at all or you slide.
Waiting eagerly for the next one in the series.
Wow it's amazing
Have u seen the vedio😂
@@lohith.32 I'm engineering so utilisation of feature of 1.5x speed is maximum use by me.
Make a video on car
Aerodynamics .. please
savvy ad for BMW! i like it
Sir make a video understanding😕 Microwave communication in mobile towers
ooooo let me help when you want to take these analyses off-road. I like how you didn't just show the SAE slip definition. Terramechanics all the way!. These videos are cool.
Your animations are beautiful
Hell yeah awesome video
Watching this video made me remember about F1 Tyres
the graphics is amazing!
Amazing content, these videos must be used to teach in underdeveloping countries which are unable to fund high fee of education.
Very excellent and detailed graphics.
These people are making RUclips a great place.
Great video and animation quality! btw that tyre is rotational and supposed to spin the other way 0:50 ;)
Please make a video on working of EMP
At 4:44, it says that longitudinal velocity is measured at non-braking wheels. I think this is incorrect... It is supposed to be measured at non-driven wheels. What do you think?
excellent
Excellent
Can you pls say that, why the moving car will stop at one place even if breake is not applied
Awesome vid!
Waiting for the next episode!!!!!
Con u suggest any channel for chemistry
Excellent video 👏
Plz upload slip angle and friction behaviour of tyre.
I like how a BMW X is the model for this vid ;)
Quality content. Thank you
These graphics be so simple but so fuckin on point
As a drifter, I explain it to people that it's like dragging an eraser on table.
But you need to twist the eraser as you drag it
Nice information 👍🏻
Do you do videos for commercials?
The coefficient of friction doesn't change does it? Isn't it constant? It's just the friction force that changes
Difference when only stationary and slipping. Slipping has lower fictional coef than stationary. Say, car is easier to drift when u already drifting it, but when its grippy, u need more power to drift it.
When the slip is zero, the friction coefficient is not zero, that's the pure adhesive friction coefficient. The force, what can be transferred is calculated from the force pressing the two surfaces together and the coefficient.
Top quality
Care to dicuss slip angle in relation to adhesion limit ?
Very helpful
If we learnt like this society would progress a lotttt faster
which is EXACTLY why we don't learn like this...
can't have people walking around KNOWING things...
i cant pay attention. im trying to figure out what this car is. like in body style. it looks like a mix between a sedan and an SUV but not a hatchback. i cant decide if i like the way it looks or if i hate it.
nice vid. thank you.
the adhesion region at the region does adhesion at the adhesion region
Does anyone know if an LT tire in the same size as a p metric tire inflated to the correct pressure according to the load inflation tables would have lower ground pressure or higher ground pressure ? They remove the 10% padding that they add to p metric tires for SUVs and the weight rating after that adjustment is lower. You'd think the LT tire would have lower ground pressure but I'm really not sure. Does anyone know ? Would it also have a larger contact patch ?
Please Sir a video upload topic on the motorcycle engine please sir reply something
Yes sir
In which app this kind of video making?
0:29 - This condition extists, sort of, if that tire were inflated to its maximum cold pressure and allowed to roll along a flat paved surface by itself, without a vehicle.
Couldn't understand 10% but as always you are awesome
Who else has no clue whats going on?
😂
