G-Force, Jerk, and Passing Out In A Centrifuge
Thanks to the Starrship team for arranging this! I'm also over on their channel, flying with the Blades: https://www.youtube.com/watch?v=iWY3-1gOrxk • At the Royal Air Force training centrifuge in Farnbrough, pilots learn how to avoid G-LOC: g-induced loss of consciousness. Let's talk about g-force, about jerk, and about how to keep circulation flowing to your brain. FAQs: * Isn't 3.6g a really low g-tolerance? * Yep. Turns out I would not qualify to be a fighter pilot. The average range for g-tolerance is 4-6; no-one was expecting me to pass out. The centrifuge team do not deliberately try to G-LOC people! To be fair, though, I'd done a few earlier runs with only minor effects. * What g was the RAF person at the start pulling? * That's Marcus, from the Starrship team, and he was successfully pulling 6.5g with the help of g-trousers: they plug into a compressed air source in the plane (and in the centrifuge) and act as a lower-body tourniquet to keep the blood up top. They are very effective. * Why did you shake and shudder when regaining consciousness? * Those are called "myoclonic convulsions", which is a fancy medical term for "muscle jerks", and they're a common side effect of recovering from G-LOC. * What did it feel like? * I'll answer this in more detail in a video over on the Matt and Tom channel soon, but in short: I don't remember it. I was doing the breathing maneuver, then everything was wobbly, then we were stopped! * Is this a sponsored video? * No: the RAF and Starrship had no editorial control over this, and no money changed hands. Obviously, though, they gave me a spin in the centrifuge, and I'm collaborating with them over on their channel too!

  • If you have questions (what did it feel like? why did you convulse? isn't 3.6g a really low tolerance?) pull down the description, I've answered a few there! And if you see someone ask a question that's in the description, please point them there.
  • The highest G-Force ever survived is a record officially held by racing driver Kenny Brack, when he crashed heavily during a race in 2001 and measured 214G at peak. He made a full recovery and I know him personally. I'd love to see you do some sort of episode around this knowledge.
  • Did you live?
  • That G-Force face is the same as when you fart in a sleeping bag.
  • Hell, I get motion sickness when on a swing..
  • I wonder if there is any significance to the fact that you had 3 waves of convulsions. 1) Your eyes open and you start breathing again but you still seem unresponsive. 2) Your eyes start looking around and you lift your head up but you still seem unconscious. 3) You regain consciousness and start talking again.
  • Snap, crackle, and pop... is that a joke..?
  • isn't that dangerous for the brain? no? like its a jelly
  • “One take!!!”
  • He essentially died there for a moment. Poor guy.
  • *Blimey!*
  • That G LOC was distressing to watch
  • Would this happen if you upside down?
  • thumbnail: when he put it in without telling you😩😩😩😩😩
  • Tom, I'm solidly impressed. Glad you came out OK. Your stuff is always amazing ;)
  • Lmao his face when he passed out lol😂Thankyou Tom for doing this just for us.
  • I thought that the presentator was a jerk and that "jerk" was passing out in this centrifuge
  • 4g and you passed out? i was going 3g and i was fine
  • Heavy orgasm
  • What was going on when he was going like "pah" and then lost consciousness
  • *insert windows shutting down tune*
  • *5 g's activated* *jerk off*
  • How can you jerk when you sit in a centrifuge?
  • Would you ever do more computerphile vids?
  • The one in the Netherlands looks better in my opinion
  • Metre per second per second per second per second.......
  • has anyone thought that the title was g-force jerk in a centerifuge. and the thumnail went so well with it
  • It looks like the star fox characters have metal legs
  • *PAHHH*
  • When designing railways you have limits on how quickly you can change direction, which in effect are rates of change of acceleration, so I suppose that's a use for jerk
  • Ayy Fanborughs my neighbouring town
  • Wait... the controller sits in the Middle of the centrifuge?? Holy crap!
  • Is that lady a doctor and a fighter pilot lmao. What a legend.
  • In the related vids is one of Tom nine years ago soaking his fingers in pineapple juice... oh, how the mighty have fallen!
  • He looked like he had a stroke
  • I did 4 g’s when i was 12 years old like it was nothing
  • Are you an intp personally type I am
  • 3.6? Pussy
  • He’s so shook
  • Speed, accelerator, jerk...and what's the accelerationof the acceleration of the acceleration (and so in...) called? And: is there an absolute limit?
  • That's why piloting an aircraft or going into space wouldn't be for me.... Although I'm sure the photographs I could bring back would largely compensate for the profuse vomiting and vertigo. Reminds me of the movie Apollo 13, where Fred Haise said Buzz Aldrin had been motion-sick all the way to the Moon....
  • Welcome to the Vommy-Go-Round :p
  • I can’t get over the thumbnail 😂
  • *Farnborough!
  • Evolution doesn't design anything.
  • That was scary
  • Scary watching you jerk around a little as you came back to consciousness. Glad your okay. You are brave for doing it.
  • When you wake up thumbnail
  • And here i sit, glad yet dissapointed, that he did not jerk off in the Centrifuge until passing out.
  • Actually I have researched a jerk for years, if you need feedback feel free to ask me anything.
