Why do we change gears in a car ?

Why do we need to change gears in manual transmission vehicles? We know that, while driving a manual transmission car, we should start it in first gear, shift to higher gears as we gain speed, and shift to lower ones when climbing a hill. But why should we do it?
The gear system and some technical terms like "crankshaft" used in the video are not completely accurate. This is to make the video easier to understand.
All I'm aiming with the video is to give you the basic logic behind gear shifting.

3:00 wrong formula, it's actually angular velocity

[@psyphy]

Yes, you're right!

[@diptoacharjee7538]

Interesting. A Clash Royale player, who's supposed to be brain-dead, knows his physics well.

[@meltedWax169]

Well, thats what you get when you fit people into boxes. Not everyone fits.​@@diptoacharjee7538

[@yuchenmei7011]

This is the exact explanation I want. Simple to understand, right to the point and super clear. Thank you so much!

[@psyphy]

Thanks a lot for the nice words.

[@anshulnihartrivedi1156]

I've watched many videos on this trying to understand but your video is the greatest by far! It has an easy to understand explanation and simple animatoins which help convey the point well, unlike other videos which use the whole drive train as an animation. Thank you for the great video!

[@psyphy]

Thanks a lot for these nice words.

[@badyahelamin8386]

This is like the 6th video I watch on this topic and I am finally able to understand how gears work💯👏

[@zeries1471]

So clear and easy to under stand. Thank you!

[@psyphy]

Thank you!

[@amrithamanoj811]

Thankyou so much...I'm going for driving class since 4 days ... my teacher is now teaching me to control the steering and accelerator after that only we'll move on to gear ...but i dont have any idea about it(like the role of gear other than reverse and normal)now its so clear thankyou

[@balakay1538]

this is the best explanation of the concept I've ever seen

[@hackedclient01]

thank you so much for this video. perfectly explained. spent my whole life having no idea why cars need a transmission.

[@Dvdylol]

Never knew how car components like these worked and this explanation really helped thanks 🙏🏿

[@arunodaya55515]

Best video available on whole of TH-cam regarding this topic! Wow🎉 many thanks 🙏

[@rahulpandey6159]

Very well articulated. Exactly what I was looking for. Thank you.

[@psyphy]

Great to hear!

[@Maple_Tachibana]

Dude nicely done! Easy to understand unlike other videos it still is over complicated. This was basic of the basic.

[@psyphy]

Glad it helped!

[@aadarshahumagain402]

If this was your own creation, then you are going to be a very good presenter

[@psyphy]

Thanks a lot!! This made my day

[@EvilSapphireR]

Holy crap you have the most soothing voice ever! The content was spot on too. Absolutely precise, to the point explanation for the regular joe.

[@psyphy]

Thanks a lot for the nice words!

[@remithraghavan3041]

Very simple but powerful explanation. Excellent work...!!!!

[@psyphy]

Many thanks!

[@devikaa4022]

Thank you!! loved the video. Yesterday was my first driving lesson day and I was all confused about the gear and hated it. This video made me realise the importance of it.

[@psyphy]

Glad it helped!

[@enocksuva2942]

[@nitubhuwalka9620]

That's one of the best explanation anyone could ever give...thank you so much....

[@psyphy]

Thank you! Glad it was helpful!

[@mertdaniel00]

Perfect explanation! Thank you for this video, i understood finally how the gears works...

[@oldschoolgaming4303]

Thanks dude ! Your explanation video is easy to follow ! I learned a lot ! You earned a subs my friend.

[@Cinder5195]

I appreciate this video a lot, it makes this understandable and is entertaining. The visuals definitely helped, I think the size of the gears helped me relate it to the size of a lever. I also appreciate you pointing out that commen sense can be wrong

[@psyphy]

Thankyou!

[@qiarwercn291]

Although your accent is hard for me to listen to, it doesn't overshadow the excellence of this video.

[@golakhchandrasahoo9505]

Thanks for this wonderful knowledgeable video.

[@magodelviento]

Excellent explanation, good video until the very last 👏 .

[@achikavengergarohills3048]

Great... Learnt torque which baffled me . Rpm seems easier to understand but the inverse relation between rpm and torque ok getting it though not fully... damn physics...but I do kind of understand torque a little now... But the big gear for more power output yep needs more learning

[@FlutterShipp]

This is what I was looking for. Everyone says change gears and how it's changing. But nobody tellz why to change it ans why it exists

[@hamza-chaudhry]

Brilliant explanation & great graphics

[@saifeegallant]

first gear has the shortest diameter.. its shown opposite here.. why?

[@psyphy]

As I said at the beginning of the video, this is only a schematic representation of gears focusing only on the physics behind them. It doesn't exactly look like this inside a car. You can refer to this video: th-cam.com/video/wCu9W9xNwtI/w-d-xo.html by Lesics to see it from an engineering point of view. No matter how it is implemented, the physics and logic behind it will be the same, which is what I'm trying to explain here.

[@kalaasmna9116]

Two ways for gear to work,big gear and same number of teeth=first gear,small gear with high number of teeth also works the same way.
Thats what I understood/can visualise,correct me if Im wrong.

[@boggycocktail2545]

I wanted to cry, what a video bro! Full of concept wisdom and humor, all at the same time. 👍
