Formula SAE Crash

[NarKs]

In all honesty, why even post this if half the video is a pretty grey tarmac?

[8484dano]

good camera work dickhead

[bdcoller]

@8484dano  Wow. You are classy!

[redtop91]

LOL Oh engineers.....

[keithyoung]

omg something interesting quick point the camera down!!!

[ryN45678]

"OH MY GOD A CRASH!" "i better point this at the ground." wtf camera man?

[ForGodSakePlease]

Took a beer with one ex-UQTR team member the other day. He told us the story of the event: Last minute fix before the comp, they added a bracket. When the new guy from the team put the suspension back on one of the rod-end (On both sides) wouldn't fit so instead of telling the guys the bracket wasn't working he grinded the rodends so he could mount it. They've missed it at bolt check and well you see the results, after some runs it failed miserably! Found a wheel in the bleachers!

[Julian3190]

ugh thats a horrible sound. Kissing away all that hard work. :(

[soupjr99]

The fact that both wheels/tires flew off simultaneously only helps proves that it wasn't a "lack of lug nut tension".. but rather suspension failure.

[gunnerkylling]

Or perhaps bad dimensioning or failure on the A-arms

[saturnv3]

HORRIBLE camera man

[wetmelon]

Worst EVER

[05American]

@saturnv3 agreed.

[phil656565]

i cant believe any engineer would build something that would do that... even if it was loose lug nuts any engineer shouldnt have missed that

[mop65]

Rubbish, it has nothing to do with stuff like loose nuts. the idea of the competition is not to build something conservatively, but to optimise the desing with regard to weight etc.

Under braking, a lot of suspension parts break each year.

[phil656565]

and saftey should be first... putting your driver in danger like this is absolutley rediculous

[CPMaverick]

Um, no, there are not a 'lot' of suspension failures each year. Engineering race cars may be about pushing the limits, but nothing good can be said about a design that fails, especially as easily as this one. This is a learning experience though.

[woodenclock2]

@CPMaverick

it should never fail DURING the race.

ideally the car should disintegrate just as it crosses the finish line (a sudden catastrophic failure without any warning or loss of performance until the race is over).

anything less means that the car was over engineered and the added weight should have been used for ballast.

purely theoretical of course, assuming infinite funds and with no safety concerns

[miky1988]

Yeeeeeeeeeeah! From RaceUP team Italy

[WoRtH2die4]

you learn by your failures

certainly won't happen twice ;)

[dembkomj]

FAIL!

[jhonnybob999]

tran!!

[AwesomeAlvin]

rod end in bending lol

[mop65]

Exactly, I'm doing it this year and our car from last year had REIB - oh look, there goes the front wheel under braking!

[laughsatposers]

lol damn that's kinda funny.

[toctuning]

I just can't stop laughing about how funny that sounded... I'm a terrible person, I know it, but you gotta smile hearing engine rev, breaking steel, then chassis dragging ground.

Funny vid, hopefully nobody was hurt and it was ONLY a learning experience.

[skyseeker901]

I know, i am a horrible person; someone could have been seriously injured, and thats nothing to laugh about....

but i still cant stop giggling XD

[PseudoScienceb20]

That's why this is a student engineering exercise.

[MrJohannVegas]

And that's why the dynamic events have such enormous safety envelopes now.

[jilbruke]

I take it that was a brake test... Yep, the rears locked...! We lost a LR wheel in testing in 2001, and spookily on our next car lose the same wheel in competition.

[aronhalt]

This happened to me after our event in 1999. I took the car out on the highway after coming back from Detroit and I lost one of the rear end lower A-Arm rod ends... Just snapped off at about 60mph. Luckly I just made a bunch of sparks dragging the muffler. Kinda scary though.

[donewithfuess]

remember kids

don't forget your torque wrench when come to competition!

haha jk i hope the guy was alright

[Franckidoo]

It was not a lug nut problem but more a low A-arm rod-end failure + a badly welded bracket. Interesting video but it was not a good moment for our team...

[jameshurst123]

were you using rose joint / rod ends in bending by any chance? a common fault on fs cars, encapsulated sperical joints are the best way...

[unlostfool]

What you don't see is the woman in the stands getting smoked by one of those tires.

[bdcoller]

True.

[Superchickenman159]

@unlostfool shut up dane cook
