Why is it called science garage if the whole thing happens in a kitchen?
nice point
Cooking pretty much is chemistry.
Adrian Perez science kitchen
Tell me about it
reminds me of LTT
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.
WOW mind BLOWN thank you!
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.
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.
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
@@presinaldlol what happened when it blew up??
@nc_g8gt I don't think we'll ever know
I miss this guy and this type of script writing. I forgot how much better Donut use to be.
Then that idiot took the channel by storm and it's a race to see who can act the most hyper and absolutely retarded
what are you talking about, this is unbearable. he is so fkin annoying I just skipped a whole 5 minutes in the beginning.
Yeah whatever happened to this guy he was my fav
I was wandering the same thing!!
@@zchhrrs4590he quit in 2019 to work for motortrend and kbb
Bring back this series. It's the best car explanation series on CZcams.
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.
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
You forgot metal gear solid

plastic gear viscuous
Nano machines son.
@@dangerm2156 Nano *FIDDLES* son!
Kept you waiting huh?
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
TheMelodySweet ten bucks this chump is lying.
Is it worth a being a mechanical engineer? I was thinking of pursuing that
@@Carlos-hr9kg no, most that ive talked to arent actually doing it despite their degrees
john dowe thanks for the input. Appreciate it :)
"The second thing I like to grind is gears"
But what's the first one?
*Concern*
Herb
It's obviously James
Your mom.. boom..roasted
Babies
My mind's telling me no.
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.
Metal Gear....
Take a shot everytime he says 'gears'
Damn, I'm not twenty anymore.
Shit I can’t I don’t have any
Sry underage
Does it count if I already went through a whole bottle of Grey goose and half a bottle of Jack on Saturday night?
And now I'm arrested for a DUI
How familiar with the gear wars are you exactly?
Pu Derrick ah a man of culture I see
I was looking for this
Uhh not at all
Woah, a fellow intellectual among a sea of ignorant idiots.
Oh, I think I see someone I know, you'll have to excuse me.
The reverse gear is a straight cut gear in all cars and that's why reverse sounds louder, right?!
Yes
that_G_EvanP y though
@@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?
Yes
Top Gear!
SnelleHarry 5th gear
DAMMIT I was just about to say that
._.
the OG Top Gear though with clarkson hammond and may. not the "new" top gear.
bottom gear
Damn, I miss having this dude on Donut
Me too😞
Same
He’s at Motortrend now
As a mechanical engineer, we needed this kind of enthusiasm in undergrad!
**comedy intensifies**
you have a video
@ThomasKT he's a pleb :')
Shit can I get subs I'm on the road to 2k lol
@@guthannight stop begging for subs
how the hell is this a joke? Bad excuse, because someone called you out for begging for subs.
Bring back science garage please, these were (still are) great!
I hope Bart is doing well. I miss watching him explain stuff like this.
What happened to him?
@@GustavAhlbrand He left for personal reasons if I remember right. Had a kid shortly before he left.
@@Crypticdragon1 damn I was just wondering:( gotta respects him for doing what he feels is best
@@GustavAhlbrand the first explanation was he left for family reasons but I’m pretty sure he’s at motor trend now
"Cars that like to go fast" is up there with "The bus that wouldn't slow down"
How to make gear sounds interesting.... Say gear louder.... 😂
STRAIGHT CUT GEAR IN BMW M3 GTR!!!
Denis Novendra Um actually it's full name is: BMW M3 e46 GTR
@[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.
halofreak1990 it’s like saying I have a mustang
You get the point and mental image so you don’t need to say 1965 or 2015
You can just say "E46 gtr"
@@leilalopez6003 BMW M3 E46 GTR ALMS
I love the whine of straight cut gerars! Its the best accompaniament to motor sound, even better than turbos and superchargers IMO.
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!
Jessica started a land war on an Asian Continent
Which Asian continent?
Why are you always top comment? Lol
You keep using that word. I do not think it means what you think it means.
Aidan Barrett Some have told me it’s because of my stupid smug face
@@gremlincc it's cuz your white
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)
It’s July 2022 and I still want Bart back
No M3 GTR Video???? Btw, great work! Science garage is my favourite thing in Donut.
I love these videos man! Perfect mixture of humor and science. Thanks and keep makin science garage
I was expecting a Gears of War reference and I wasn't disappointed. Thank you
Damn, I want to see Zach and Bart in a single video
You didn’t mention opposing helical gears eliminating the need for an axial bearing.
I was looking for this comment!
I wish this series continued. Helps me so much with my education
I love the little puffs when his hand hits the bench. Classic!
rip to the golden era of donut media
gotta say this is my new favorite channel man, get science garage shirts!!!
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.
This is the clearest explanation on the dif in heli vs straight! Love it guys
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
"Left handed and right handed"
THIS IS IT. I SUB FOR UP TO SPEED, STAY FOR SCIENCE GARAGE.
The puns are so beautiful.
maegan22my you are
DSSR your mom is beautiful
maegan22my such love
Wow, look at those thirsty fuckers.
Bloody FX well haven’t fucked in 2 weeks you better believe I’m thirsty
Just finding these old episodes and this guy was awesome!
he's the boss guy. donut just realized their other presenters get more views
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
Dude, you’re hilarious! You’d make an awesome high school automotive instructor
Thanks a lot man. This channel is amazing
cant wait for this series to come back
Nothing wakes me up like
:rolls dice:
Straight and helical gears
2:08 is when he gets to the point.
Cool vid! I learned some stuff
Love these videos
0:53 no richard gere ??, well it' about time to unsub then...

Discovered your channel with this absolutely great video. Fantastic job :D I'm subscribed
Thank you for all the entertainment
What do you know about the "Gear Wars?"
Its " How familiar are you with the gear wars exactly?" Peasant
As the owner of a bugeye rexy... This is the video i need before we get more boost in it :')
Shiii bugeye gang
@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
orange flavored potassium first, wtf is that username aha, and yeh, hated the look 2 years ago then it grew on me
Currently learning Kinematics of Machinery and this is so fun to watch :D
56 seconds was all it took me to subscribe, I love it
The best satisfying straight-cut gear transmission racecar is ALMS version BMW M3 GTR.
Bart gets funnier every episode
Nicely explained.
Yes I was hoping you'll make this one
why is the teamfortress scout talking about gears?
why not
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.
I love these videos keep up the good content
Dude I’ve been trying to figure out the advantages and disadvantages of both as of recently so it’s insane that this video just came out 😂
We hereee🤠🤠🤠
Its okay Dolan. Always remember that James's dad never stuck around.
Please keep it up. I'm your number 1 fan from KualaLumpur,Malaysia! I will spread the love
This video really grinds my gears.
What happened to this guy I love him and I need him back 🤣
I'm sad about it too, he went to motor trend after taking time off because kids
You forgot about Metal Gear Solid
I need a dog box transmission ASAP! Great video guys
this guy always makes me smile
Im watching this on the toilet
Ok....why do I need to know that?😂
So ?
I miss this guy & this series!! Used to be such a blast!
who puts these little things in like Bart’s hands at 5:04 😂 i love it
Gears Brosnan, Gears Morgan, Morgan Gearmen, Samuel L. Gearson. The list of gear puns are limitless 🤔
He miss Metal Gear :(
Limitless, just like gears in a Fast and Furious gearbox
Daniel Gearin
I miss Bart.
Applause for their animators! Superb! Thanks
Man thanks a lot, you made that simple enough

Ladies and gentlemen, that's how racism ended
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.
you forgot about metal gear solid
Love you guys, and what you do hopefully your channel followers starts picking up some speed, but honestly looks like you guys put in alote of work into your vids your my favorite channel, thanks :)
I LOVE THIS CHANNEL
you're grinding my gears
Ok Peter.
RAMCHARGERS!
I love the little dust clouds the animator adds on the table
I ❤️ science garage!
What kind of the people will hit that dislike button? I wonder
Cyclists
James
OAPs
Electric car drivers?
People that are disappointed that he missed an obvious gear pun in the beginning
haha 1mn
This show, is why we subbed. 2 thumbs up. 👍 👍
My favorite from the channel
I'd love to be a racist, I love driving cars and driving them fast
Life is a race and we are the racists.
car community is definitely full of racists
