Anti-Gravity Wheel?

I am here at the University of Sydney where
the mechanical engineering shop has built this incredible piece of apparatus for me.
It is a forty pound, that is nineteen kilogram flywheel on the end of a meter long shaft. Can you imagine trying to hold this out horizontally
with just one hand at this end? It is virtually… it is impossible, ok? No I’m going to let go. You going to be able
to hold this at all? I hope so.
Can you lift it out? Make it horizontal – hold it, hold it, hold
it. Come on. Just try to – I want you to hold
it out horizontal. See if you can. Hold it, hold it!
Ahh, come on! No.
What I’m going to do is I am going to spin this up to a few thousand RPM and then I’m
going to attempt just that, to hold it from one end and have it out horizontally.
Five, four, three, two, one. Boom. I’m going to let go with my left hand. What
you’ll see is that the shaft remains horizontal, see it going around there. It almost looks as though the wheel is weightless.
How does this work? Well instead of pulling the wheel down to the ground as you’d expect,
the weight of the wheel creates a torque which pushes it around in a circle. You may recognise this as gyroscopic precession.
For a more detailed explanation, click the annotation, or the link in the description
to see my video on the topic. Here I want to try something more extreme.
I’m going to try to lift it over my head with one hand while it’s spinning. Wish me luck. But before I make the attempt, Rod wisely
suggests that I first check if I can lift the wheel above my head without it spinning. OK, let’s prove that I could lift it, just
this end, without it spinning. Here we go. agggh
I mean it’s just kind of awkward with the hand.
Careful! Ah, che
Careful! Ha
Oooohhh Just barely. Oh goodness, do you even lift?
Clearly I do not. Undaunted by my lack of strength, I’m going
for it, but I want to make sure the wheel is spinning as fast as possible to give me
the best chance of success. Give it ten more seconds.
Ten, nine, eight, seven, six, five, four, three, two, one. Pull!
Go. That was perfect.
Now I’m going to release my left hand and holding only with my right hand at the end
of the shaft, I’ll try to lift it up over my head. This is a forty pound, nineteen kilogram
flywheel. Ready?
Here we go: three, two, one. Beautiful! Let’s go again in three, two, one. Nice!
Smooth. Three, two, one. It feels incredibly, incredibly light as I
do that. When you said it felt incredibly light,
yeah you mean when you’re lifting it feels light?
Yeah. It shouldn’t!
I know. Hahahaha
Honestly, I have lifted it up with one hand when it’s not spinning.
Yeah. And it feels really hard to lift it up, like
it’s a big effort. Yeah.
But with this, when it’s spinning it honestly felt like it was just…
wanting to go up by itself. Yes.
It felt like I was not struggling like I was not putting in the amount of force that you’d
think to lift that kind of weight. I bet if you let it go, it’d crash down to
the ground. It’s not weightless! We can’t do that though. We can’t do that
part of the experiment. What we could maybe do is I could stand on a scale and we could
see what the weight of me plus that apparatus does, while I’m lifting it up over my head,
see if I get lighter in essence. You can see that just my weight is about 72
kilograms. Now when I pick up the flywheel it goes up to about 91 kilograms, which makes
sense because the flywheel itself is about 19 kilos, that’s about 42 pounds. Now we’re going to spin it up and I want you
to make a prediction. As I’m lifting it over my head, do you think the scale reading will
be more, less than, or equal to 91 kilograms. What do you think? You can make your prediction by clicking on
one of the on-screen annotations or if you’re on mobile you can click a link in the description. Five, four, three, two, one.

  1. What if while holding it in one hand I also try to balance the torque with muscle power …will I still be able to lift it so easily?

  2. 7000 year before aliens made their planes on earth were based on this phenomena . they totally removed gravity effect and moved with speed of light

  3. Wheel spining left side
    You pulling it up and moving left side

    Do it in opposite direction like
    Spin the wheel left side and pull it up and move it on right side. You will feel the double gravity force.

    You can use the gravity force for instant tranmission/transport

  4. what happens when you connect 2 flywheels on one shaft and spin one wheel on one side but other to other side

  5. In India there is a weapon called 'Gada' used same in this manner. The gada is a club or blunt mace from the Indian subcontinent. Made either of wood or metal, it consists essentially of a spherical head mounted on a shaft, with a spike on the top.

  6. It's just that it's a lot harder to turn that fast-spinning flywheel from its origional level than a non-spinning thing.

    Oh yeah, AND the angular momentum that resulted from the gyroscopic effects can be turned upwards using a force somewhat similar to a centripetal force, which is easy to exert as it doesn't require energy.

  7. Imagine a vehicle, round shape, that has lots of this thing arount it in a shell instead of wheels, that is called Flying Saucer!! Damn! Aliens exist!

  8. It simply uses "magnus effect", it doesn't defy gravity, just has another force providing normal reaction to it in mid air letting it partially balance gravity

  9. If you spun up two wheels, one on each end of a rod, barbell style, so that the wheels were spinning in opposite directions to cancel out the procession, would it cancel out the effect and simply be a very dangerous spinning barbell?

  10. I believe this trick works like quantum physics. Like light, the weight requires an observer, or in this case a strongman.

    It is lighter, the quantum mass, when someone is lifting it.

    The usual mass when someone is weighing it.

    I believe it is in two states, or two masses, at the same time.

  11. Would it work the same way if u added two flywheels that both spun a different way? And can u do a video of it if its possible?

  12. Los masones de mierda o poderes fácticos, luchan para que la energía libre Nunca sea de usó común para la humanidad

  13. I think it isn't anti gravity. Because you moving forward. You just only throw the energy. Asia people know this very well…

  14. Pity you chose not to mention of Professor Eric Laithwaite, former Professor of Heavy Electrical Engineering at Imperial College London, who first demonstrated this experiment, and who you've obviously copied it off. Your experiment trying to weigh yourself is flawed, because you will be bouncing up and down a bit on the scales which will throw the result.

  15. Porque os engenheiros não enchem os interiores dos caminhões de cargas com algumas rodas como essas e assim poderiam diminuir os excesso de peso que a gravidade exerce sobre a carga e no final isso resultaria em baixo consumo de combustível fóssil!!!

  16. This is super simple and no, it’s not how flying saucers would fly if they existed.

    Centrifugal force. When the disc is spinning really fast, they centrifugal force is almost as strong as gravity which explains why our skinny host can suddenly hold the stick with the spinning disc at one end.

    The trick ONLY works when the spinning disc is held vertically because gravity pulls towards the mass generating it while the centrifugal force pulls equally in all directions away from the axis of the spinning disc. If he had held the stick with the disc straight over his head, the trick would fail as the centrifugal force was pulling to the sides instead of downwards.

    A flying saucer would therefore need to be vertical instead of horizontal and even then, the centrifugal force would only help carry the discs, not make them or anything else weightless. And that doesn’t even address the energy needed to spin such discs fast enough to ALMOST nullify their own weight.

    Just think about it.

    Elementary, dear Watson.

  17. The answer to anti-gravity is right in front of you. Why don't you see it? The answer is still invisible as a knowledge which already has been disseminated, but the answer is always in front of you. We all live under it's rule every day. If you make a million guesses, what are the chances that one, or twenty are correct? Now focus on those possibles. Then narrow down the amount of tests of the ones you choose. Of what amount of those are false leads, and wasted on the true, and correct answer to this difficult problem? I believe those who come close to the answer are stifled and stopped from their proving grounds, and this is the battle we are constantly forced away from with distracting physics that only flicker its real power.

  18. What happens if you accidentally come into contact with that spinning disc? How fast is it going? Is it like touching the rough surface of a running angle grinder with your finger?
