Space Shaker - Backstage Science

[Yeahrrrrrr55]

this is a music instrument! at 4:52 it sounds exactly like a timpani!

[MegaMonkeyExtreme]

That machine would do wonders in the chocolate claw games.

[mrteemumilto]

Breaking items deliberately is blasphemy!

[DontMockMySmock]

seems more like backstage engineering to me

[pvskpraveen]

I was waiting for the 20Hz moment when we can actually hear the movement of the platform.

[lobstermendez]

@pvskpraveen i thumbed up your comment, so don't take this offensively, but i'm a car audio "basshead" and at high enough spl I have personally heard all the way down to 14hz, but we're talking about like 155 db or more.

[pvskpraveen]

@lobstermendez thanks, I dont see any offence. But may be someone can explain why textbooks say 20Hz as lower limit when you were able to hear 14Hz...

[BrettahAU]

@pvskpraveen Recording hardware tolerances/limitations, probably.

[lobstermendez]

@pvskpraveen ya, i understand that text books say that, but what i assume is that there aren't a lot of scientists (not that im saying there arent any) that have been able to produce high enough spl possible for hearing these notes, i'm talking about hearing them in vehicles that are basically sound generating machines. i mean even at 155 you can barely hear that low. that much spl is very hard to produce even by bass competitors that have been around for years.

looooool

Back in the 70s we did this for the electronics packages being placed in the Viking Mars landers. We would be running automated finctional tests on the pacakges as they were shook, both through frequency scans and while playing actual recordings of a Titan launch through the shake table to simulate a real launch. During these shake tests some of the electronics packages had price tags in the millions of dollars, so you really do get that puckered feeling.

[BeanTVYWG]

Seeing a rocket launch in person is something I need to do. Being part of the crew being launched would also be acceptable.

[damianpaz]

I can't help imagining Mr. Bean siting on a table trying to have a cup of tea on top of that machine ^_^

[CongletonDirector]

Awesome! thanks...

[JonJwhittaker]

vibration facility? what is your mum in there?

im so sorry...

[fossil98]

If that thing were a subwoofer...

[douro20]

@fossil98

It's actually quite similar in operation. It's driven by an amplifier, in this case I'd imagine it's close to 50kW. Two opposing liquid-cooled voice coils drive the shaker table back and forth.

i hope by the end of 2014 i'll get my degree in aerospace ENG...thats if the world wont explode at the end of this year....

Thanks so much brady.

"You never actually learn anything about an object until you break it."

I like this guy.

[defaultuser88]

hey ladies... check out my vibration facility

[eggroll9000]

Breaking things for science. That's gotta be a cool job.

[MarkArandjus]

Shake it like a polaroid picture!

[ToxicBassUK]

Would be fun to sit on.

[motopix45]

You've been busy putting up vids. Love it!

[1DARBY1]

cool, what would happen if you strapped a person to that?

[feuchster]

@1DARBY1 death. It would scramble your brains pretty hard.

[zbe8]

@1DARBY1 You are asking wrong question. What would happen if you had sex on it? ;D

[MrMaffen]

hell of a backscratcher

[Probablyacowtbh]

Neat!

[Lampet6]

Nice video, as alway :-)
