If you've ever wondered why you even need to torque things to spec and cant just max out every bolt with those big muscles you got from typing ITworlds comments, then this is the video for you! in this episode of Bumper 2 Bumper we look at some fascinating fasteners. The B2B team goes through the science of tension strength and yield. this episode also has some very stressful experimentation to prove our theories on torque spec.

Yeah i don’t like this hick soundin dude in the beginning he weird
I love learning stuff while laughing
Lb*ft lol
It’s not that we don’t have time, or don’t have a torque wrench, it’s that we don’t have a CARE LOL
So what you're saying it is... greasy ugga dugga bad?
the hospital fed james oompa loompas to make him feel better trust me i helped jk i didnt im just an 11 year old kid
The stingray is great!!!............ I'm not Sébastien, but I can't imagine a free vette to not be great...
imagine if this wrench slipped and got your knuckles.... in the cold in the dead of winter? Its nicer than you think I can't feel my hands 😜
I dont like watching this host as much as the other ones but they seem to give him all of the interesting titles.
Perfect example of when righty tighty becomes Righty loosey
Just come ask the new guys at my job who always say “yea I can run an impact” lmao then fast forward to me replacing the stud😂 HAND TIGHTEN YOUR LUGS!!!!! A problem that’s 100% avoidable smh these new guys have me working in “strip city”
What if I’m a wiz attack helicopter?
I actually broke 2 socket wrenches trying to get a bolt off my tire a few weeks ago.
Bumper to bumper became science garage
5:21 I always feel "sorry" for this poor guy and how his show gone...
Well because you can lose your wheel on the highway.... had a shop over tighten my lugs once, and now I never ever leave their torques
LOL the torque meter! "Bro i'm scared lol" lmaooo. And how you gunna hide behind Nolans S197! Haha poor Fords!
Don’t forget the German Torque spec. Guddentight!
I’m surprised your breaker bar didn’t fail @ 1000 ft. lbs! That would be 100 lbs of weight placed 10 feet out on your stainless pipe. Which you seemed to have accomplished. Hmmmmm
It snaps and you die inside. It then turns a 1 hour job into a few days worth and that's if your even lucky Enough to get the snapped bolt or stud out.
What happens when you over torque a bolt? It breaks. Ok, now I’ll watch the video.
You could probably use smaller bolts and actually make this work if your didn't use shit grade 5 bolts lol
Ever see a Mercedes oil cap? Literally can not apply torque to them. They're basically gas caps. Not sure what the hell you're talking about.
I tried out Omegle one day and a girl asked if my dad was divorced because he has a F-150. But she has a Toyota Tundra, now I might be wrong but to me it seems like her parents bought that truck since she looks in her teens.
Awesome video. Appreciate it as always!
or you’re a mechanic, like me
????
I wonder how much Omaze could really help good causes if they actually donated a bunch of money rather than spending it on sponsors, advertising, cars, and cash giveaways
These guys could replace my mechanics of materials professor
Diameter ,grades of steel, etc...was the small bolt and large bolt a grade 8 bolt?
That moment when u forgot corona and u look at the visor and say always good to have eye protection 🤣😂🤣😂🏁😅
Cue the brains of the episode at 5.25 😂🤣
Had a broken 3/4" torque wrench in school and we were trying to torque U-bolts on a semi. When we realized that something was wrong, no one believed that we had a "broken" torque wrench and said that we just weren't there yet. Ended up stretching the bolt to the point where it snapped in half and sounded like a shotgun blast.
i wish he was my mechanics of materials professor, maybe i would’ve done better 😅
Seriously only came to see you guys break the bolt. I was nearly hit by a bolt that broke while tightening, it wasn't little...
Uhhh they break. Saved everyone 12 minutes.
Cool video! The material science you talked about wasnt completely correct though, Plastic deformation doesn't necessarily involve breaking molecules (breaking chemical bonds). For example with metals and metal alloys (which is what youre really talking about) there is a lattice (arrangement) of metal atoms and/or metal-nonmetal molecules For example steel has iron atoms (Fe) and iron carbide molecules (Fe3C, aka cementite). In elastic deformation, the arrangement of these particles (atoms and or molecules) deforms and like you said returns to the original arrangement. But plastic deformation involves the particles slipping and will rearrange in a new arrangement but the chemical constituents are the same and no molecular bonds have broken (in metals and metal alloys at least). Again, great video :D love your stuff and im super glad youre introducing car folks into the engineering and science behind how cars work :)
It fails... haha
F-150 GANG!
I do not like this man
Dude what a bunch of wimps... get a torque multiplier and a 3/4" torque wrench
This is the like the Mythbusters of automobiles and I'm here for it
People laugh at my pipe-and-weight type torque wrench like you guys used. Many mechanics simply can't afford a 600 Ft-Lb cap or higher wrench so for loads like this and more I use lengths of 2 inch schedule 80 aluminum pipe and a special fabricated 3/4 drive head to do basically what you do in this video. I use a hand spring scale for the force and it is important to apply the force at right angle (90 degrees) to the distance from the fastener center line. Check the accuracy of your spring scale by lifting known weights - It is an accurate system although much more cumbersome than a large torque wrench but better than guessing with a huge impact.
The people who laugh at your technique are the same kids who laughed at the person studying for the final who's getting an A regardless while, at the same time, hoping they pass with a C.
Because you dont use a torque wrench, it doest mean that you need to over torque them. Just tighten them enough
Thanks for putting the ad line down guys😶
Your mask and colored hair say alot about you
I miss science garage more and more every day
Surprised the ratchet didn’t break
BRO I THOUGHT YOU HAD A ENGINEERING DEGREE!!! LMAO SUCH A BASIC CALCULATION! Dude stop explaining mechanical engineering right now please.. and dont ever again
You can also measure the length of the bolt as a unit of measurement
It might be a sponsorship with Omaze but honestly, I think it should be a partnership. Donut is the first place I saw Omaze, and continues to be the only meaningful place that I see it. I think it would be a good fit for both companies. Donut would be likely to be seen as a more involved media company, and Omaze would be likely to be seen as a company that cares about the little guy (relatively speaking). Either way I love that they work together, and I love both companies!
It would be so loud if they broke it
That’s dope y’all partnered with a local union. 👍🏼
I never thought my 9th grade engineering class would be useful but I’ll be damn. Basically half this video was about that class 😂
I'm torqued just watching this
I still want to see the thing break...i thought y'all we're going to pull it off, but perhaps it's a job for HPC 👀
rotary flywheel bolts...
We have to fight for our country war is coming civil war fight or die
This was actually a bit of a stupid experiment because in the first bolt they broke the bolts thread so if they really truely wanted to see they would’ve needed WAY more torque
reason why a lot of car bolts are now xx newton meters and xx degrees also why replacement is asked by manufacturers
I think it’s also worth mentioning the differences in the grades or property classes of bolts and some of the misconceptions with that. Grade 8 bolts are stronger but more brittle because of the additional carbon, Stainless bolts are in fact weaker than carbon steels, etc. also talking grades you can talk case hardening. The layer of hardened steel in bolts will penetrate about the same amount so a 1/4” bolt will have the same case hardened thickness as a 1” but the percentages are greater in that of a 1/4” bolt. Platings and coatings are another good topic for things like hydrogen embrittlement. Things that could be another episode though.
I know for a fact that they put over a 1000 ft.lbs. of torque on that bolt. I do Pressure/Hydro Testing on gas plants, which requires us to torque bolts all day so flanges don’t leak. We use a 1000 ft.lbs. Torque with a 4 foot extension which makes it 8 feet long. With that you can apply 1000 pounds with no problem. Just imagine a 13 foot pole. I’m pretty sure you guys were more closer to 1700 pounds than 1000 pounds.
Science Garage disguised at B2B
I use German specs "goot-un-tite"
So here's why there's no up to speed.. (129) car/truck videos (make model and sub model) videos. (7) oem perf. division videos. (7) aftermarket perf. divisions. (2) racing (F1, group b) videos. (2) race car drivers (Petty, Miles). (1) race track, the ring. (3) engines Hemi,LS,Cummins. (3) motorcycles. (2) semi trucks. 4 misc eps. Santa sleigh, quattro system,foxbodys, john deere tractors. (2) deleted eps. and a Redux episode of the RX-7.. ⚡⚡⚡ and now there out of ideas maybe?
Bro what kind of breaker bar is that.
What happened to Up To Speed
3:56 Basically just the good old qaurter turn before strip
Intro to material science 🧪
Hope to see science garage again!
I’m fucken dying 💀😂😂😂😂
Ok then mr smart man how am I supposed to prove my masculinity without tightening it as much as possible
11:05 guys..... Spell check was a thing in the '90s. Is this some sort of poorly-spelled Easter egg hunt? I swear, there's one in every video
7:56 anyone else pushing the screen away lol
Wish i had saw this video when doing material enginnering. Books are not that fun
3:30 after the material experiences plastic deformation, it will still have some elastic deformation that will reverse or 'snap back' when the load is released but your stress/strain curve will be shifted by the amount of the plastic deformation.
Congrats to Sebastian tho
So what happens now if you over twerk tho?
Something you didn't cover is how the part you're bolting down can get distorted. Cylinder heads are very particular about this. If the bolts are not torqued evenly enough it can warp the head. There are a lot of parts like that, including wheels and brake rotors. If the lug nuts are not evenly tightened on a wheel, or if they are overtightened, it can cause the brake rotor to warp, and then you get brake pulsation. Also, I'm super disappointed you didn't break that bolt. I wanted to see tools fly.
You don't know how you got suckered into this? It's cuz you got a pickup. Pickup owners are automatically drafted. That's why a lot of guys own station wagons or SUVs instead.
Lets get some f's for all of our fallen slinky bretheren
Replaced my timing belt on my 98 civic with no torque wrench ran perfect for 30 thousand k until a guy ran a red light:(
What happened to James?
Lug nuts get 3 ugga duggas, suspension bolts get 5, hub nuts get all the ugga duggas
“””””hand-tightened”””””
Donut: **does mathematical calculations and experiments on torquing a bolt** Me: if righty righty becomes righty loosey, it’s an oopsie 😂
I love that b2b became science garage 2.0. Very different hosts and energy, but love the content about how shit works
The 1/4 +plus turn calculus deduction. Interesting.
He is tall
7:30 but you guys do realize that torque applied to bolt increases, when bar is getting more horizontal? When you put bar almost vertical and hang bags of sand, you applied torque so small, you probably do with one hand and a small ratchet. Torque is force multiplied by arm on which its applied, and when you are using gravity as a source of force arm is measured in horizontal distance. Vertical bar = 0 arm = 0 torque even if you hang 10 tons of sandbags on it
...please dont say bust a nut that alone is excrutiating
Now I'm thinking of the autobot that said "That nut is supposed to have 10,000 pound feet of torque, not 19,000!"
I ugga dugga everything!!!
That’s a serious cool & educational viddy Mr. Bravo 👏
I'm more surprised the pin inside the breaker bar didn't shear.
Use less lipstick man.
Puss yall should have kept going on torquing the ball
This is useless to me. I love it
kinda like, in terms of acoustics, how it takes 8 trombones to be 2x louder than 1 trombone
Stuff is made to made at least 1/2 or a quarter the rate it's actually good for ...
Alright but how I look at thinks with my 20 year old car is I rather it be a lil too tight am secure them to lose an leaking 😒 especially in places I don't ever want.to be in my car again
