Anti-Gravity Wheel

Anti-Gravity WheelI’m here in the University associated with Sydney exactly where the mechanised engineering shop has generated this incredible bit of apparatus personally. It is really a forty lb, that is actually nineteen kilogram flyWheel about the end of the meter lengthy shaft. Are you able to imagine attempting to hold this particular out flat with only one hand only at that end? It’s virtually… It’s impossible, okay? No I will let proceed. You going in order to maintain this whatsoever? I wish so. Are you able to lift this out? Allow it to be horizontal — hold this, hold this, hold this.

Come upon. Just attempt to – I’d like you to keep it away horizontal. See if you’re able to. Hold this, hold this! Ahh, seriously! No. What I will do is I will spin this up to and including few 1000 RPM after which I’m likely to attempt that, to maintain it in one end and also have it away horizontally. 5, four, 3, two, 1.

Boom. I will let opt for my remaining hand. Exactly what you’ll observe is how the shaft continues to be horizontal, view it going close to there. It nearly looks as if the Wheel is actually weightless. So how exactly does this function? Well rather than pulling the actual Wheel right down to the floor as you’d probably expect, the weight from the Wheel produces a torque that pushes this around inside a circle.

You might recognise this particular as gyroscopic precession. For any more comprehensive xplanation, click on the annotation, or the hyperlink in the actual description to determine my video about the topic. Here I wish to try some thing more severe. I’m going to try and lift this over my personal head along with one hands while it is spinning. Desire me good fortune. But prior to I help to make the try, Rod sensibly suggests which i first check basically can raise the Wheel over my mind without this spinning.

OKAY, let’s prove which i could raise it, simply this finish, without this spinning. Right here we proceed. Agggh I am talking about it’s just type of awkward using the hand. Cautious! Ah, che Cautious! Ha Oooohhh Simply barely. Oh yea goodness, would you even raise? Clearly I actually do not.

Undaunted through my insufficient strength, I am going for this, but I wish to make certain the Wheel is actually spinning as quickly as possible to provide me the very best chance associated with success. Provide it 10 more mere seconds. Ten, 9, eight, 7, six, 5, four, 3, two, 1. Pull! Proceed. That had been perfect. Now I will release my personal left hands and keeping only along with my correct hand at the conclusion of the actual shaft, I’ll attempt to lift this up more than my mind.

This is really a forty lb, nineteen kilogram flyWheel. Prepared? Here all of us go: 3, two, 1. Beautiful! Let us go once again in 3, two, 1. Nice! Sleek. Three, 2, one. This feels extremely, incredibly light when i do which. When a person said this felt extremely light, yeah a person mean when you are lifting this feels gentle? Yeah. This shouldn’t! I understand.

Hahahaha Truthfully, I possess lifted this up along with one hand when it is not re-writing. Yeah. Also it feels very hard to raise it upward, like it is a big work. Yeah. But with this particular, when it is spinning this honestly felt enjoy it was simply… Wanting to increase by by itself. Yes. It experienced like I wasn’t struggling such as I wasn’t putting in the quantity of force which you’d want to lift that type of weight. Love gardening?

I bet should you ignore it, it’d crash right down to the floor. It’s not really weightless! We can’t do this though. We can’t do this part from the experiment. What we should could perhaps do is I possibly could stand on the scale and we’re able to see exactly what the pounds of me personally plus which apparatus will, while I am lifting this up more than my mind, see basically get lighter essentially.

You can easily see that simply my weight is all about 72 kgs. Now after i pick in the flyWheel it rises to regarding 91 kgs, which can make sense since the flyWheel itself is all about 19 pounds, that’s regarding 42 lbs. Now we will spin this up and I’d like you to create a prediction. Because I’m raising it more than my mind, do you believe the size reading may be much more, less compared to, or add up to 91 kgs.
