Homemade Balancing Toys Part Two // Homemade Science with Bruce Yeany

[@smartereveryday]

How's the knee?

[@YeanyScience]

I had both knees done at the same time, it was not a pleasant summer but it's amazing how much better I feel 6 months later. Great to be moving pain free again, Thanks

[@koosnaamloos4291]

@@YeanyScience Glad to hear you're ok!

[@BealsScience]

You know you are doing things right in the physics/education world when Destin checks in on you!

[@abrahamcavazos1984]

I was going to ask you about your knee also. Someone did it before I did. I'm glad you're doing better. Anyhow, great to have you back Bruce. By the way that balancing hand saying goodbye.... I thought it was awesome.

[@YeanyScience]

Thanks Craig, and I really appreciate that both of you guys took the time to stop by my channel and leave a comment .

[@henrithebault5722]

I am 46 Yo and you make me want to go back to school. So much to learn and do not have enough life to do so.

[@LakeNipissing]

I am the same age, and I have told Bruce many times on his older videos how much I wish I would have had a teacher like him when I was in school.

[@brinjoness3386]

You might be too late for a gold at the Olympics for running, but nobody is too old to learn or go to school.

[@Watchyn_Yarwood]

You're such a great teacher! I wish my children, heck, even I could have had a teacher half as good as you!

[@fernandoaguirre2682]

Greetings from Mexico. Great videos, great lessons but most important is the LOVE and the PASSION you put in every project. If we all had the same passion, the world would be a better place. My respect, maestro!

[@PolarKantele]

We need to make Mr Bruce a Minister of National Education

[@lotsagrapes]

Nicholas Cage can induct him in lol

[@javiergomezvillarreal2002]

Nice to see you back Mr Bruce. Thank you

[@RaExpIn]

I'm on my way of becoming a teacher in chemistry and physics and these videos are extremely inspiring! Keep up the great work! :)

[@newhorizon1521]

I enjoy watching your scientific videos. You are a great teacher

[@cterrell1343]

Excellent video! Thanks for even more ideas! I am in the process of making prototype balancing toys as making projects for my school's Science and Technology departments and will pass the link to this to the relevant teachers too.

[@addington3o396]

This mans the real MVP! Great work man ! Can’t wait till next vid!

[@YAHaqabNatsariym2701]

With the battery operated plane you could see how the center of gravity changed with the increased motion of the plane and the battery lifted with the increase of speed! Same with the bees spiralling as they decreased the rotation increased due to the weight of the bees down the incline. Pretty cool stuff! Thanks for the cool video.

[@sarthak8350]

India really needs teacher like u In india physics is just learning definitions and doing numericals No focus is given to practicals

[@videocurryofficial]

*Respect* 👍

[@MakeScienceFun1]

Great to see you again! Loved the plane with the battery.

[@chrisp6582]

Great to have you back Bruce!

[@YeanyScience]

thanks, nice to be back!

[@Youcanscienceit]

8:42 Most interesting moment - When the plane gets going with enough momentum the battery swings up and the plane get's pushed down. What is going on!?! I think...that it has something to do with the fact that the instantaneous linear momentum of the battery and the instantaneous linear momentum of the plane are at different heights placing them each above and below the center of mass there is a torque created. Once the mass of the airplane and the battery rotating in line with - at a plane the same height as - the center of mass everything balances out again. Or nearly if it weren't for gravity since the pivot point starts out above the center of mass the position of the center of mass gets displaced from plumb a bit so probably the whole thing processes a bit as well while rotating.

[@Reach3DPrinters]

Centripetal force throws battery outward, which pivots upward at balance point fulcrum. Same thing you said :)

[@chance1986]

Or... the upper cylindrical surface of the battery (along with the flat bottom of the case) forms an "airfoil" and creates vertical lift. This causes the battery to rise. ;-) OK... OK, at these speeds the lift is probably in the micro-Newtons. But it sounds cool.

[@logan398]

Your so smart

[@angelonious8785]

Oh if you had been my science teacher I would have been a physicist. At least I have your videos to base projects off of for my children. Thank you!!

[@YeanyScience]

glad you liked them, and I am especially pleased to hear you trying some of it with your children

[@dwurry1]

Interesting that the electric plane changes the center of mass as the centrifugal force increases in unequal proportion because the masses are at unequal distances from the center of balance. There's also an interesting problem in that the masses being at different masses are different weights from each other. (force * distance = toque). The torque changes with rotation.

[@muruganandhamem]

welcome to your regular schedule. keep making such videos which motivates us to keep learn. thanks a lot for your efforts.

[@Mevangeli]

Bruce is back!

[@hunterboat]

You're back!

[@deepakk1347]

Yeah... Mr. Yeany back!

[@dechaa.1549]

Glad to see you back.

[@wot_noobclown5621]

I’m sure this guy has some sick moves on the dance floor, what a legend 😘

[@BealsScience]

Love it all - as usual! Thanks for sharing.

[@danielclements439]

Back in the classroom! Nice!

[@rubenpereal.9906]

As always... Excellent video

[@peterschmidt2702]

Schön dich mal wieder zu sehen! Nice to see you again!!

Danke, es ist gut, wieder da zu sein

[@bascooymans8917]

Thanks for this vid. Glad to hear you're doing fine.

Omg you almost hit 200k subscribers!!! good luck

[@Maninawig]

That tweeny bopper (the first one).... If you put a concaved wheel on the middle, couldn't you make one of those bicycle tightrope walkers?

[@hamzaahmed1578]

You are an awesome teacher

[@incxxxx]

nice!

[@laurencegoldman4639]

It would be cool to put your mini lights on there and make light photos.

[@3dprasad]

these videos are getting interesting more and more

[@paulsharpe3794]

Hi grate to see you back

[@JaisimhaAllalghatta]

Nice to see you back

[@YeanyScience]

thank you

[@AloisMahdal]

Somebody should make Room Exit flash game on Bruce's workshop.

[@abhavishwakarma5035]

That was so cool!

[@LuisPerez-xc1yc]

I thought I was retired. you recovered? I like your videos are ingenious

[@YeanyScience]

I retired last year, had surgery and have recovered, while still in the classroom, I shot some footage, so now I am combining that with new footage

[@backstept]

It's interesting to see how the motorized airplane tilts downward due to the centripetal force from the battery end. I wonder how it would perform if the battery was moved to be level with the airplane.

[@carultch]

It looks so weird seeing the plane banked in the wrong direction.

[@antalz]

Still having some audio distortion on the intro unfortunately. I think it would be worthwhile to discuss why this does work if the wire is shaped like a ^, but not if it's shaped like a v. In other words, why does this not work if the masses are above the contact point?

[@YeanyScience]

I know the audio continues to be a problem, this was shot with older equipment, not sure if it's the equipment or me, good news is that I've updated my equipment so we'll see. Good idea on the mass above the contact point, I have another set of toys that I will tackle down the road, including a high wire bike rider, I will make a note to tackle this then.

[@antalz]

@waterrocketsrule If I'm getting this right, you can only comment on people's videos if you have similar videos on your own channel? And my unrealED video doesn't count as educational because you said so?

[@Rand0mManic]

Note how the momentum of the bees is improving the systems behaviour..

[@UselessCat]

Love the videos

[@YeanyScience]

thanks Mason, aren't you in school now?

[@UselessCat]

Bruce Yeany yeah it’s advisory and I do my work

[@el6700]

Professor you need to teach again!

[@chance1986]

But he is.

[@MrFmiller]

Try suspending weights on strings at the ends instead of fixed objects. I suspect the motion will become chaotic.

[@YeanyScience]

this is why I always look forward to posting and seeing what new suggestions I will find.

[@MrFmiller]

Expounding on that you might suspend weights at different lengths or multiple weights on each string to explore the effects of pendulums on rotation

[@dmawzx]

Классный учитель!

[@johnrhine7211]

Hey Mr Yeany. Hows it going? we all miss ya at Annville Cleona.

[@YeanyScience]

Thanks John, I'm doing well but I really miss not be in the classroom anymore

[@johnrhine7211]

@@YeanyScience I'm Glad to hear you are doing well. They have Mr. Simon in your classroom now and Mr. Metzgar moved upstairs and Mrs. Mohn is in his old room. Iv'e had a rough year since I lost my dad to brain cancer back in January.
