It's not like 1 genius came up with this stuff, it took many many generations of trail and improvements, the basic principles go back as far as Archimedes.
I’m a former mechanic so this stuff is second-nature to me, but this video is absolutely brilliant as a visual aid for teaching my son what the clutch pedal action is actually doing in his car. Thanks so much for creating it!
I want to drive a manual and this little video taught me so much about how it works. When I understand how things work, it’s usually easier for me to grasp how to do them
In the late nineties, when they said, "Oh the web means all information will be free," this is the kind of thing I wanted it to be. "Here's all the these explained". Excellent work, sir.
Indian educational Videos are usually free. Huge population can support few free educators as around most students take STEM subjects and prepare for entrance exams. In west, channels like these can't survive unless paid. (This channel is Indian btw)
I mean, when you consider how the interworkings of the system operates, it's really a bunch of simple systems working together. There's nothing about an engine, transmission, or clutch that are really that complicated, it's just that they work together in a larger, more complex system. The actual principles being applied and the science behind how they work have been known for thousands of years, meaning the only thing stopping us from having vehicles like this beyond a few hundred years ago was the ingenuity of someone willing and able to put them together. While I don't understand how most things work, it's easy to understand how this works and that shows just how simple the design really is.
The entire automobile system is really complicated to understand if you're only familiar with theory. It really needs to be understood practically imo.
I would like to think that THIS WAS the original purpose of bringing the Internet to the masses...not facebook nor twitter....open the knowledge to improve the society.
I'm literally over here watching this for fun while some poor engineering student somewhere is cramming for an exam watching this same video. Hello friend, I believe in you.
LOL! Clutch OBVIOUSLY doesn't appreciate you. Clutch just isn't prepared to treat u like a real person, because Clutch is not a real person deep down inside to be honest.
I think some brilliant german guy was the first to built the 4-stroke engine as we know it plus the transmission to go along with it. Truly masterlevel engineering!
@@paraskaith5027 Exactly. All the technology we have around us today is the result of thousands of years of experimentation and slow development (until the 20th century when tech began increasing exponentially). People just keep building on and expanding upon previous ideas and inventions. It's funny when you think about it. Stone Age people had all the ingredients to make mobile phones, computers and even space shuttles, they just didn't know it at the time.
*HEY PRACTICAL* how you doing? I never knew you liked _mechanical engineering_ i thought you were exclusive to _civil engineering_ glad to see you strolling on other engineering videos.
Terrible narration. The pronunciation and editing for the voiceover make it sound like a robot who has no idea what the words mean. Extremely distracting and difficult to follow.
When I was still in the secondary school, my chemistry teacher used to drive like that. She would drive out of the school parking and drive for about 200m before shifting from the first into the third gear. Her car engine sounded like it was about to take off, her diesel engine easily exceeded 5000 RPM and that's a lot when we're talking about a car that's more than 15 years old.
Lmao i used to do this in my driving lessons aswell. Most of the time i skipped shifts. Much gas in 1 shift to 3 or in my second to fourth😂 my teacher always thought it was weird. But it worked so he was like alright go on We drove in a kia ceed (6gear sport edition)
@PCGamer UK You are right. But if I were a car manufacturer wanting to know the thermal resistivity of an engine component, or the amount of force required to snap a tension belt over time, I'd probably call the guy with the mechanical engineering degree. Everyone has their purpose, college isn't as bad as conspirators make it seem to be. Just WAY too overpriced.
@@bmxgod4193 sigh... this is your justification for remaining ignorant I suppose. You would NOT have ANYTHING in the modern world handed to you on a silver platter if somebody hadn't bothered to get an education. This video is supposed to inspire you to go to school and learn engineering. Do you really think anything in the way a clutch works was figured out by uneducated people? So yes.. you DO need a college education if you want to be a successful designer or engineer. I'm mostly self-educated in physics. From gravitational waves and the collision of neutron stars down to quantum uncertainty. Enough so that I can have a cogent conversation with people more formally educated than I am. But I also know whoever it is that makes the next level breakthrough in cosmology towards Professor Hawking's elegant theory of everything is going to have a math and or physics Ph.D.
Carbon Crank yes you’re right, for careers like engineering or others you most likely should get an education simply because it’s a lot of content and you also need labs and equipment to work with and practice as well as someone with experience to lead you. I said you don’t need college to be successful, I’m talking about just being successful in general like there’s a lot of other ways and things you can do. But for example a mechanic, no you don’t necessarily need college.
This was really educational and easy to undestand. I've driven a manual my whole life and never knew the science behind how the clutch worked. Very cool video. Easy upvote from me.
I'm not a big car guy - I don't know anything about them other than where I last parked - but the whole transmission system is a really beautiful and ingenious piece of engineering; absolutely amazing how it's evolved over the years. Excellent video, many thanks!
@@TLC7 A V is correct, manual transmissions really aren't that complicated, generally speaking. A typical 5-speed is pretty straightforward - with a little knowledge, it's quite easy to identify which gears are which just by playing with a model of the internals. Rebuilding one is time consuming, but again not particularly difficult (of course, given the proper tools - that's the hardest part is having the right tools - and the most expensive).
Ideas like these take a lot of trial and error. Lots of cleverness put into the design, but it was by no means conceived by a single person in a day. This genius is a result of decades of engineering trials.
@jonesyterp Everyone is... Everyone's genius.. coz everyone's got the same brain.... But it depends on how YOU use your own brain.. capacity is limitless
SOME engineers are amazing. I work in the blue collar industry as a welder and I will say some of the dumbest people I have EVER met have been engineers. I think it has something to do with logic and trying to make things simple but then over simplifying something at the same time.
This is the condensed vocational education that children should learn in school so they leave high school with the knowledge to immediately begin one of a dozen different careers. I love RU-vid for that education. So much DIY and clear, concise explanation, plus visuals. I spent my youth getting straight A's in subjects I barely scratched the surface of in my 20's and 30's. I feel like I've learned more useful information in my 40's than I ever did in school. Just watching YT and DIYING the crap out of life. Awesome channel guys...subbing!
To all the kids reading this and thinking "great, I can drop out of school and watch RU-vid videos, I can learn more this way", I'd say: No, you can't learn more on RU-vid. Those engines are designed by people with PhDs, not by people who spend too much time on RU-vid.
@youtubeShadowBan Yes, if you watch this: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o96K8fkOrG8.html then you will learn more than you would in high school. Because the content is made for college students. But the "popular science" type of channels won't teach you more than high school, far from it. And the usual "you can learn more on RU-vid than at school" comments are always on popular science channels.
Lube and strong materials, but mostly lube. And that's why if an engine is anything less than extremely overbuilt, running dry will ruin it very very quickly
The friction facing burned off the clutch of my 1968 Datsun 510 when the hydraulic system became clogged and left the clutch in a partially engaged position. The car was only 4 years old at the time with about 35,000 miles on it. Things have improved greatly in 50 years.
Saw an entire 2.5 minute ad in full. I am not able to help you at patereon, so guess, this is how I can help. :) I learnt something awesome today. Thank you for that.
@@ashwinkumar8990 so when the clutch is 'biting' a small amount of power is being transferred through to the wheels? Just enough forward power to cancel out the backwards rolling force of gravity? Thus a stalemate and the car stays stationary? Then the clutch fully engages, the power gets fully transferred to the wheels and the car shoots forward?
You have to understand the differences between types of motion neede to make a car move: Rotary Going round and round. Reciprocating Going backwards and forwards in a straight line. Oscillating Swinging backwards and forwards. Linear movement is movement in a straight line in one direction. Study this first and branch from there. Next try to understand what 4 strokes means: Intake, Compression, Power, Exhaust. You have to transfer the reciprocation power gained from the four strokes of an internal combustion engine to rotary power in some way for to the wheels to move. Hence the names "Transmission" and "differential". You can't stop the engine to change a gear because that doesn't make sense to shut the car off to change a gear so that's why you need a clutch. It alows you to connect and seperate the reciprocal motion of the pistons and crankshaft without stopping the engine and then transfer that motion to rotary power by selecting the correct gear for the proper speed you want to travel via the transmission, drive shaft, and differential and through the axel to the wheels. The differential changes the direction of rotary motion to move the wheels. (Rear wheel drive) This is why there's a difference between BWHP and HP. You lose so.e power though this process by the time it gets to the wheels. Just copy this comment and paste it to notes, then look up all these definitions. This is simplified but the basic concept. Then look up the different systems of an automobile. Cooling system, braking system, Exhaust system, drivetrain, suspension, Lubrication System, Electrical System, ext. It seems complicated but it's just common sense. There's some brilliant mechanics out there who can barley wipe thier ass😂 Don't over think it.
I have searched for this video many times over the years waiting for someone to make it - this is perfect for showing teens when learning to drive - thank you!
This was so very informative! Now, I know how to drive a manual transmission. My first car, when I was 15 was a manual but I’ve never fully understood exactly how it all works. I’ve seen other videos that explain how a clutch works but none were as clear and easy to understand as this video. I’m a visual learner and I must say, this video answered all my questions! Everything finally makes so much sense. Thank you thank you thank you!! Well done.
Yeah, although I wanted to drive manual from the time I was a little kid. So, my first car was a manual. Hard to find one that isn't either worn out or looks rediculous.
Great visualization. I'm always so afraid of slipping the clutch on hills, but its good to see this kind of description, I feel like i can more confidently and precisely practice my hill starts without fearing heavy damage to my components. Sawpping a clutchplate is no big deal, paying for a new transmission... uhhhhhh naww This is a wonderful video, thanks!!1
@@chbrules heres an even better idea. Dont text and drive. You may think you can do it fine and im sure youll keep thinking that right before you're killed in a car accident because you couldnt put your phone away. I dont understand why you would brag about reclessly putting your life and everyone elses lives at risk because you dont know how to set the phone down while driving
Cars now are built with so many distractions --- navigation touch screens, control touch screens, hands-free cell phones with voice recognition and voice-synthesized text readers, dozens of almost identical buttons on the steering wheel and console, dash and so forth --- that the manufacturers now tell us we can't live without electronic compensation devices such as "adaptive" cruise control, blind spot monitors, rear-view cameras, and the rest. When I learned to drive, there were a handful of controls --- basic operation such as brake, clutch, and throttle pedals, steering wheel, lights, wipers, turn signals, lever controls for the heater, air, and defroster, one knob for the radio (on, off, and volume, plus preset buttons, no need to fiddle with the knob on the right), and a toggle for the day-night mirror. Everything clearly and logically laid out, no need to take your eyes off the road. No distractions from the primary task of driving the car.
This was super helpful! I am learning to drive stick shift for the first time, and having an understanding of mechanically what happens when I step on the clutch helps so much!
That makes so much more sense, I kept thinking, how can the clutch be partially on? It’s because of the friction thing ‘clutch disk’ part, not the gears. Thanks for the info :)
My dad's letting me drive his old car for the first time today. This videos one of the requirements for me to be let drive it, and honestly, it has helped a lot, so thanks!
@@TheMechanicalHermit how is a modern dual clutch electronically controlled transmission not more effecient? There is dramatically less time between gear shifts.
It is a shame that they don't make many cars anymore with a manual transmission. It has been a great theft prevention system. I had Dodge Dakota for 20 years with a 5 speed manual. Can't find newer trucks with them...
Thanks a lot friend for posting this. They expect you, when you go for a driving license, to just learn everything empirically and just know, "when your car does this, change the speed", with no further context. Videos like these are very helpful.
at about 5:25 : The partially released clutch acts as a brake…. This is true… however, when stationary uphill NEVER use the clutch at its "sweetspot" to stop from rolling. This is VERY bad for the clutch as it causes incredible wear AND heat!! However, to show how an uphill-start can be performed it it is pretty good. Although, I find the use of the handbrake easier, more control. I am from EUrop (NL) where most drivers are "native to manual" as I call it.
I´m from Czechia (central Europe), we also have mainly manuals here, but i find uphill start easier with clutch, but it also depends on the situation, if for example I´m waiting for a traffic light, I´ll use the handbrake because I´m waiting long and I want my legs to rest for a while, but if the stop is short enough I prefer the clutch start, I feel that I have more control of the car, so I think it is just about what are you used to.
Well if it’s actually to start moving the vehicle then the bite method is good. But if it’s to stay stationary for more than a couple of seconds until you can move again then yeah it’s an horrible idea to ride the clutch.
I always just make sure to be quick and get going before it has a chance to roll backwards. Only once did I use that "technique" of partially releasing the clutch and I knew it must have been terrible for the clutch. I had no idea people do that regularly.
The handbrake method must always be used. "Riding the Clutch" leads to premature failure and shuddering & its replacement is quite costly. If you have to pull away on steap hills often, then rather get an automatic. Or start off down hill rather than uphill & use a detour to get to your destination - your clutch will last much much longer & you'll save a lot of money in the long run.
im 35 and have been driving a stick shift car since i was 15 and never knew how the internals of the clutch worked. this was cool to see what im doing everyday
This is really helpful to learn, but try not to use the clutch as a brake as they say. They did mention it causes excess wear, but only briefly. If you aren't quick enough yet to catch the car on a hill by starting normally, you should be using the parking brake to hold the car while you start and not the clutch. The time between a fully depressed clutch pedal and fully released clutch pedal is called slipping. The friction plate is in contact with the flywheel, but it's slipping on it as it brings the transmission up to engine speed. For obvious reasons, this is when it wears the most. Slipping the clutch to hold the car in place often is going to wear it quickly and is lugging the engine, which isn't great either. There are tons of great videos on here of how to and how not to drive a manual. You'll be happy you learned because it's a much more engaging and fun way to drive. Good luck!
CZ-Hk-S&W I know it. It smells like rubber burning and you will have to change the Clutch Plates. Happened when my dad was driving steep uphill with heavy slow moving traffic with frequent stoppings after 3 to 4 Kms the smell was awuful and we had to call the tenicians
Bruh I’m high as hell , I’m on my last year as a fitting and turning student and this is the first time actually understood something fully from the start , you guys just simplified my understanding of the clutch system,thank you
In most European countries, manual transmission is a given, it's understood everyone who does drive a car knows how to drive a gearshift vehicle. In the US however, anyone who drives a car with stick transmission is nothing short of a hero!
sometimes I complain about new car prices, but after seeing some videos like this one, I think it's worth it... so much knowledge involved, it's unbelievable
It stops running, no different than just turning it off. The clutch ties engine speed to wheel speed at one of a handful of gear ratios. If wheel speed is zero and the clutch is engaged, then engine speed is forced to match the wheel speed, which in a stall is zero.
Wonderful illustration. Shows how even seemingly-complicated ideas can be communicated so very easily and in minimum time, through a well-designed illustration/animation. Thanks a lot.
This video is excellent. It illustrates and explains, in a layman's terms, exactly how a clutch functions. The sequence of the information presented, the terminology used, and the illustrated working diagrams are outstanding. If school teachers and the God awful textbooks we use could present information and teach this way, we would all be so much smarter.
Another thing not mentioned in the video, a clutch has an outside and inside diameter. The reason why is because the max torque applied to the clutch is at the outermost radius. So if an engineer designs a clutch to be able to handle the max engine torque (with a bit of a safety factor of course), the outer radius frictional area and area just below it handles most of the torque. For a clutch designed to have a uniform wear rate (as uniform pressure is too idealized), the ideal ratio of a clutch's inside radius to outside radius is ri = 0.58 * ro. However, clutch desings commonly have proportions between .45ro and .8ro, depending on the space available and torque produced. If you cannot design a system to handle engine torque in the available space and centrifugal force restrictions with just one clutch, you will need more frictional surfaces, which you can calculate. A clutch has 2 frictional surfaces, one to the flywheel and one to the pressure plate. Adding another clutch gives me 4, so if I needed 3 frictional surfaces, I would have to use 2 clutches. If you would like to read more, read Chapter 18 of Machine Component Design by Robert C. Juvinall and Kurt M. Marshek.
You don’t use the outside diameter of the friction material to calculate the loading, you use the mean diameter. Yes I have designed some clutches! I have worked for the two largest clutch manufacturers in the world! LuK and VALEO!
As a very good very accurate description how a clutch operates and also explains why certain cultures wear off faster then other better design clutches to include clutches with dual friction plates also it needs to be discussed and a diaphragm clutch the diaphragm well fatigue and time depending how many time s it is depressed it is best Tori place the entire clutch assembly why the original clutch begins to slip if for some reason it's slips at a low mileage then replacement or relining the friction disc only is needed
As far as I know, you REALLY shouldn't use the technique that they have shown here to get your car going on an incline. This is called clutch burning and can kill your clutch extremely quickly, which is a very expensive repair. This is because when you are staying on the biting point of you clutch, there is an extreme amount of friction happening between the clutch disk and the pressure plate, which creates a lot of heat and creates excessive wear on the clutches friction material, which is why it is called burning the clutch. This is extremely discouraged by a lot of automotive professionals, and can destroy your car extremely quickly. On a manual transmission car, ALWAYS use either the handbrake or the footbrake in this scenario, and have the clutch be somewhere between engaged and disengaged for as little time as possible. Also, another tip: Don't ride the clutch while driving, which means resting your foot on the clutch. This can also cause excessive wear, although more slowly. The clutch is only supposed to be used for short periods of time, which also means that, for example at a traffic light, instead of being in the first gear all the time and standing on the clutch pedal, switch the car into neutral and get off the clutch until it is time to get going again, your clutch is going to thank you.
5:37 - Not recommended, that's how you burn your clutch if you keep braking for too long! You start smelling and eventually you'll see smoke. Do it quick, or use your hand brake!
I would recommend using this method for about 1/4 second. When idling on a hill, use foot brake and leave in neutral & foot off clutch. When you're about to take off, press clutch in, get to friction zone, let off brake, and get car moving all within that quarter/half second. When people transition from handbrake to moving, I typically see overreving and babysitting the clutch. * btw do not have clutch pedal pressed unless you're changing gear. In my roughly 8 years of driving, I've never had any clutch slips/fail.
The technique showed does not work with my car, it shuts down immediately whenever I release the clutch without giving it some gas... I basically have to agressively roll the wheels if I'm starting on an uphill.
@@zaktrytodive7582 Do you have a gas car? It's very hard to pull off when running a non-diesel car. If you tires spin, then you need more practice :D Use the hand brake, it will save your clutch, trust me!
I never understood how it works... till now. My friends always told "when to press" but not "why to press" All sudden I feel actually confident to go get a driving licence.
Uphill start: 1) hold clutch and brake pedals 2) instantly move your braking leg to the gas, go gas gas gas 3) release the clutch agressively after 1 sec your car will fly this way
KEEP IN MIND...PARTIAL RELEASED (or depressed) CLUTCH IS ALWAYS ...BURNING UP THE DISC the ONLY time the clutch is NOT BURNING, is when clutch peddle is FULLY depressed or FULLY released
It's not "burning" per se. Clutches are made to withstand that friction. You're "burning" the clutch everytime you start a car from a standstill or are forced to shortshift. It'll be fine as long as it's not abused.
@@Diandredofus you are burning the clutch when you hold it halfway. The clutch is not designed to slip for long periods of time. Slipping the clutch causes heat that burns the friction material on the clutch.
This is great! I've always been a very mechanically inclined person, but I have to say I completely misunderstood how the clutch system actually worked until watching this video.
