You know, normal cars(with a manual transmission) do have some straight gears: the reverse gear. Ever heard that weird noise when you're reversing? Thats the straight cut gears.
There is no actual reverse gear, except in manual transmissions. The reverse gear is just the planet gears of the planetary gearset of an automatic transmission, which use helical cut gears. Search up how a planetary gearset works on youtube before you start spurring out bullshit.
Bart failed to mention just how badass straight cut gears sound at speed. As a mechanical engineering student I love watching your videos, they are educational as well as entertaining, I think you found the right balance of being educational without getting too bogged down and bored by the theory and math behind the concepts
One of my teacher once told us that in the old days all gearbox were straight cut, even truck's one, he said the sound of it was louder than the engine once you past 50 mph
It's long gone sadly. Bart left Donut like 4 years ago :( They never made any public mention of it that I remember so I suspect it wasn't on the best of terms but I'm not sure
I was. But I've been trying to figure out what that gearbox whine was anyway. I always thought it was the drivetrain, when you get to higher speeds. I also hear it in some rally cars.
@@willmiskovich359 Its got to be cheaper to manufacture a straight cut gear than a helical. It makes reverse noisy, but how long are you in reverse to even recognize it?
@[GD] hiyarus In the case of the BMW you kinda have to, since there were multiple M3 GTRs from different types. Using the full name means people know which one you're talking about right from the get-go.
Same I love it so much that I starve my tranmission of fluid so I can hear that killer whine might be a different whine but still a radical whine hahah
Hey guys, thanks a whole lot for this series. Everyone loves to learn stuff and its better with the comedic relief and graphics. Would have been useful for me last year, when i had a test on this, but it is going to be easier for everyone else. Thanks to everyone at donut!
Actually a common engineering solution to the thrust loads caused by helical gears is by running another set in the opposite direction. Essentially it just cancels out the thrust load. Also thrust loads are used to make sure that bears stay in the desired place.
You mean Herringbone-cut helical gears? Funnily enough, that’s where the logo for Citroën came from. Founder, André Citroën, got into the automotive industry by producing herringbone gears, which were even used in the steering gear of the RMS Titanic. Said herringbone gears were also used in the final drives of Citroën vehicles, up until the Traction Avant.
@The FruitOfDestiny dam, and there stronger than rexys as well :') got a fmic, injectors, headers, intake and fuel pump about to go in soon. so it's either the block or box thats shit's it self by christmas
Well there’s only two types of people in the world, left handed and right handed! Kinda makes you wonder what all the fuss was about in the first place 🤔
funny bit, at some catholic schooles etc a while back, being left handed was considered sinful (hole devil left side nonsence?). SO even with lvr handedness we figured out how to hate eachother for that lol.
I was loling over “Gears for Fears” and then Bart tries to have a serious conversation about Race. Bahahahaha I laughed so hard I had to go get my wife and make her watch that bit with me 😂😂😂😂😂😂
Thanks Bart for another awesome funny and informative video, on a lighter note I think the middle finger is the world's first and most common lever which people use on one another.

nouse use hey i'm sorry, didnt know this was only for manual cars, and also, most cars in europe are manual, and not automatic, like in america.
Why is that?
ITS THE SAME THING DUMBASS. Manual gears are not straight cut either so stfu and go read up on manual transmissions.

Why is it called science garage if the whole thing happens in a kitchen?
nice point
Cooking pretty much is chemistry.

Tell me about it
reminds me of LTT
Straight cut gears are awesome, used them for years.
You can't argue with me because my tinnitus screams louder than you can
Lmfao
pretty sure if I drove a car with all forward straight cut gears it would trigger my PTSD from my first car's transmission grenading at 60 mph lol

Bring back this series. It's the best car explanation series on TH-cam.
I like this series. Driving 4 answers is the best series for car explanation IMO.
Was going to say the same things, guess you could say they’re much and much the same though.

Then that idiot took the channel by storm and it's a race to see who can act the most hyper and absolutely retarded

Oh, I think I see someone I know, you'll have to excuse me.
Am I the only one that knows what straight cut gears are because of The BMW M3 GTR in NFS MW.
No, I'm a fan too. Too bad the Payback abandoned M3 doesn't have that straight cut gear whine.
@@bozo6206 or the straight cut Gear transmission swap.
Too bad not everyone was here because of it...
The Gaming J.D m3 gtr is life
I was.
But I've been trying to figure out what that gearbox whine was anyway. I always thought it was the drivetrain, when you get to higher speeds.
I also hear it in some rally cars.
Missed the most obvious pun, Richard Gear.
And the clip of him not being able to get the Lotus Esprit in "gear" from the movie Pretty Woman.
PGTMR2 genius! Donut writing staff hire this guy 😀
Damn, opportunity missed
Dick Gear to his friends.

The reverse gear is a straight cut gear in all cars and that's why reverse sounds louder, right?!
Yes

How to make gear sounds interesting.... Say gear louder.... 😂

Not inserting a piece of 2001 BMW M3 GTR ALMS into an episode about straight cut gears is a sin.
yes
Indeed.
True
That's my whiny boi
What about Straight cut gears' sound? It IS loud, but also - great.
Watch that video --> "Bmw M3 GTR nürbürgring Hans joachim stuck" (not sure about drivers name)
Straight cut gears: whine.
Nfs BMW M3 GTR
No M3 GTR Video???? Btw, great work! Science garage is my favourite thing in Donut.
I wish this series continued. Helps me so much with my education
Man, this guy is so awesome! Anyone knows what is he doing these days? I'd watch more of his videos. Same goes for the script writer
The puns are so beautiful.

I love the little puffs when his hand hits the bench. Classic!
You didn’t mention opposing helical gears eliminating the need for an axial bearing.
I was looking for this comment!
"Left handed and right handed"
THIS IS IT. I SUB FOR UP TO SPEED, STAY FOR SCIENCE GARAGE.
2:08 is when he gets to the point.

rip to the golden era of donut media
Im going to go use this information to build a transmission.
Some day when i get money.
Make a fixed ratio transmission for an electric. That shouldn't cost all that much.
you need to know way more than this to build a transmission; this is just basic stuff
BRING BACK THIS DONUT
Love those little flames that pop up when ya slam your hands on the table lol
This episode has the funniest intro out of all of them. Keep up the good work guys.
"lend me your gears" lmao
this guys videos feel like im watching the onion but the information is actually correct
Nothing wakes me up like
:rolls dice:
Straight and helical gears
Oh How I miss you Bart 😢🫡
I love these videos man! Perfect mixture of humor and science. Thanks and keep makin science garage
who puts these little things in like Bart’s hands at 5:04 😂 i love it
Just finding these old episodes and this guy was awesome!
he's the boss guy. donut just realized their other presenters get more views

What do you know about the "Gear Wars?"
Its " How familiar are you with the gear wars exactly?" Peasant
I'm one of the few that watches this episodes to see the new "don't tell to my wife" part and star laughing.
Dude, you’re hilarious! You’d make an awesome high school automotive instructor
This is the clearest explanation on the dif in heli vs straight! Love it guys
you forgot about metal gear solid
