Topic: Ever heard of dynabeads?

[SiliconDoc]

mlinder, you have now, obviously admitted defeat, as well.

Are you going to come clean, or will you hide behind " it won't matter if I go into it" ?

After your little "I explained it", and my where, and your link, it came down to you claiming the reason, your "explanation" of why "they don't work", is, a washer isn't perfectly balanced.

That's "the voice in your head bub".

Have a nice dream.

Please see my sig

I admit defeat only because logic and intellect are irrelevent in wonderland, where up is down and quality of content is, at best, secondary, to lots of words stated in a seemingly near random fashion as quickly, obtrusively and inanely as possible
Buck up, though, kiddo, you've certainly entertained!

I see you've doubled down.

When the time comes, just don't forget.

would these work/help if i had a lowspot or flatspot in my tire?...plan on trying them when they arrive either way

When the time comes for what?

[Inigo Montoya]

The time for one of his personalities goes off the deep end again. we might argue a bit, we might even make some odd and maybe sometimes a dumb statement. But that guy is clearly off his rocker. I have heard that huffing glue and paint does that to a person though.

[mlinder]

Assuming they work at all, no.

plan on trying them when they arrive either way 

Try them after you ride around a bit without them, so you can at least make a valid, personal comparison.

Seriously

Wow, I thought the Charlie's thread was entertaining...I had no idea what I'd been missing...

My day job is as a physics teacher...but I think I'll sit this one out and go microwave some popcorn...

[Duke McDukiedook]

I have pop secret, anyone want some?

Now SiliconDose,

Since you have underwhelmingly explained how the wheel is a washing machine in rotation, how does the translation (linear motion of the tire) play into your bizzaro physics?

You haven't quite explained that yet.

[Inigo Montoya]

And he cant, he will just call you names and make imperious statements and in general, blow smoke till you just don't care anymore.

[Inigo Montoya]

Well I just wanted to point out his tricks so we can all try to emulate him. According to some, I am already on my way!.Not referring to you here!

Ok, I couldn't sit out any longer...and truthfully...I can't even tell what the opinions are on this whole thing.  I can't tell if people have been trying to validate or disprove the claims of this product.

actually as long as the wheel is moving at a constant velocity the linear motion of the tire will have no effect on the beads...
The problem is that any alteration of that constant velocity will undoubtedly have an effect on the motion of the beads.  This is why I would be leary of using this product.  The beads will only stay where they are supposed to if the wheel is 1. at high speed 2.  constant velocity  3.  free of deformation(bumps in road)

The moment of inertia of the wheel is nearly mr² and by increasing the mass of the "hoop" you will increase the moment of inertia and therefore the torque and the amount of force required to make said wheel spin.  This means that it is also harder to start it's motion and harder to stop it's motion.  The problem is that the added mass isn't always located at the outer circumfrence of the wheel and this all becomes very complicated to think about where the beads are during all facets of motion.  

Will this balance the wheel during travel at high speeds and constant velocity??  absolutely and it will work very well... for me though there are too many other variables to account for in motion of a vehicle that is as agile at these bikes are.

just my 2 cents...

My problem with them is I cannot understand how they would ever get to where they need to be.  what force accelerates & decelerates these little bits of matter to the low spot in the tire, or the point opposite the imbalanced mass in the wheel tire system?


Just my 2C

[Inigo Montoya]

Just a thought here. Maybe the beads do not so much balance the tire but maybe the distribution of weight around the tire somehow reduces the effects of being off balance. Just a thought.

[dilbone]

When something is traveling in a circle... the velocity of the object is tangent to the circular path.  The beads want to move in a straight line tangent to the tire.  The tire won't allow that and the beads then get "pushed" to the outside wall of the tire...in reality they aren't pushed outward but rather pushed inward by the rotating tire because they'd rather keep moving in a straight line.

It's like being in a car that is turning.  You "feel" like you're pushed to the outside of the car, but really your body is trying to travel in a straight line and eventually you hit the side of the car(or rather the side of the car hits you) and it then pushes you into a circular path.

That help at all?

[Duke McDukiedook]

But Siliconedose said that a bump int he road would change the position of the beads, so under his logic, any change in the translation velocity (in the real world there is pretty much no such thing as constant velocity) would also constantly displace the beads ON TOP of the constant displacement due to ever changing rotation velocity.

I'm just trying to point out the baloney in his flawed physics demonstration (washing machine).

I already said a lot of this, but as Markcb750 said, there is no force that causes the beads to travel to the 'lighter' side of the tire to balance it.
Anyway, discussions with crazy people is a futile endeavor. Good luck.

Ok, first I'll point out, that is exactly your condition, as well as the doubleturd guy's Dukiedook.
                                                                                                    (or maybe it's misspelled duck turds)

But, I want you to both think about something, so you have at least a single concept under your belts. I'm going to give you a laymen's analogy, that should help you understand a fixed point spinning tire has very different force characteristics than a rolling tire.
 I do this first, because wannabe's in this thread have often referred to two specific physical science law that they've heard, in order to justify their failed expanded application of those same concerning dynabeads.

 Consider a large tractor tire you are inside of , your hands and feet stretched across it's diameter, and it's centerpoint fixed on an axis (axle if you will) raised a bit above the ground. You've seen a similar situaton on TV in game shows, likely. The tire is started up spinning, and you start spinning around inside as well, gaining speed.

Now a similar situation, but this time the tractor tire is on the pavement, and in order for you to spin as before, it is rolled up, and gaining speed.

 Is your physical musculature experience (disregard sight,wind) identical in both situations ?
In which device are you able to exert the least effort to remain in the center with hands and feet extended ?

[SiliconDoc]

Good thought. With the beads distributed around the inside of tire, if the tire moves downward (from the off balance weight), the beads on the upper inside of the tire resist that movement, slowing the top of the tire from going downward too, ever so slightly. Also, the beads on the bottom of the tire float a bit as the tire moves downward, they aren't attached, so they aren't pulled down.

 The reverse occcurs if the tire moves upward.

[SiliconDoc]

But Siliconedose said that a bump int he road would change the position of the beads, so under his logic, any change in the translation velocity (in the real world there is pretty much no such thing as constant velocity) would also constantly displace the beads ON TOP of the constant displacement due to ever changing rotation velocity.

If you try get all manly and bump up against the running washer, does it suddenly go all out of whack and vibrate off it's stands ? I'm just trying to point out that what you're trying to point out is flawwed.

What the hell is this crap? So somehow a person in a tractor tire is now comparable to beads in a tire?

I'm going to give you a laymen's analogy, that should help you understand a fixed point spinning tire has very different force characteristics than a rolling tire.

And yet you try to link a washing machine to a motorcycle tire?

Just to go on a limb here. Maybe it is not your knowledge that stinks, maybe it is your analogies. And I thought mine were bad!

But Pa, it's fun to poke the looney with a stick every now and then...

[SiliconDoc]

I see, so we have one rebel student rager vin who cannot complete the simlpe exercise, and the other, lost in admitting all he does is troll. (of course, since he's with the rest of the idiots, that's ok)

I'll be back sometime after the two rebel students who demanded and challenged do their homework, or...

[Duke McDukiedook]

I think we all know who the troll here is Siliconedose...

[Bob Wessner]

OK everybody, and I mean everybody, not just this thread either. Let's stop the personal attacks and name calling. If it doesn't happen, some threads are going to get locked or disappear fast!
