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

Күн бұрын

Here are a few more example of balancing toys that are made with simple materials. Making these types of toys have been especially popular with students. Toys can be a great lead in to the study of center of mass, center of gravity, levers, torque. Also makes a good STEM challenge for students to come up with their own balancing toys and investigate factors that influence it's behavior.

How's the knee?

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

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.

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 5 жыл бұрын

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

@chance1986 5 жыл бұрын

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.

@dwurry1 7 ай бұрын

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.

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.

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 5 жыл бұрын

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.

@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?
