Imagine a plane, a treadmill, a X-wing fighter, a wheelbarrow and a cute cat on a runway that .....
Would the cat ......ouch!
Would the cat ......ouch!
Hi Cal,
Neglecting skid marks - okay. My thought is that the wheel and belt remain stationary with respect to each other. Neglecting slight movement due to the servo system having to work with some error and possible under or over damping. 😀

Quasi!
Stop that or the Wookie will be angry. 😀
BTW, just how fast can the cat push the wheelbarrow?

Well it rolls along just fine, but why not just go for a jog?
Someone's actually selling these things:

Truly Bizzare!..A bike is a low impact sport better for the ol' joints........jogging is a high impact .........and what is the purpose ?
Amazin' what you can sell these days!
Is the belt matching the speed of his brain?

Do you have feelings of inadequacy?
Do you suffer from shyness?
Do you sometimes wish you were more assertive?
If you answered yes to any of these questions, ask your doctor or pharmacist about Gin.
Gin is the safe, natural way to feel better and more confident about yourself and your actions. Gin can help ease you out of your shyness and let you tell the world that you're ready and willing to do just about anything.
You will notice the benefits of Gin almost immediately, and with a regimen of regular doses you can overcome any obstacles that prevent you from living the life you want to live.
Shyness and awkwardness will be a thing of the past, (well shyness anyway) and you will discover many talents you never knew you had. Stop hiding and start living, with Gin.
Gin may not be right for everyone. Women who are pregnant or nursing should not use Gin. However, women who wouldn't mind nursing or becoming pregnant are encouraged to try it.
Side effects may include dizziness, nausea, vomiting, incarceration, erotic lustfulness, loss of motor control, loss of clothing, loss of money, loss of virginity, delusions of grandeur, table dancing, headache, dehydration, dry mouth, and a desire to sing Karaoke and play all-night rounds of Strip Poker, Truth Or Dare, Naked Twister and of course posting pointless posts on infinite threads!
Gin. Leave Shyness Behind.

I don't want to upset a wookie, I prefer my arms socketed.
If they're on the belt then it would be a question of how fast can the wheelbarrow pull the cat, and relative to the earth how fast is the conveyor belt travelling if it has to keep up to the plane that is stationary relative to the belt because the wheels have not moved (apart from spinning) and ......did some mention Gin?

To the great Moderator of the forum who corrected and revealed the whole name of our beloved cat. A thousand blessings to you and our eternal gratitude.

Dear big and little Quasi's,
There are growing pains with everything. The auto censor removes bad words for obvious reasons, it just turned out that it also removes them when they are not being used inappropriately. Thanks for the uh...umm...patience and gratitude.
We at diyAudio try to please.
Anything else we can do for you? A bottle of Gin perhaps?

So if this is the case than how can the wheel make progress along the belt without the wheel turning faster than the belt? If it lines up everytime, there can be no progress regardless of thrust. That poor plane is still stuck and now needs a new set of wheels.
Hi Cal,
Instantaneous motion and an error (lag of the belt) should be expected. The belt is run by a servo.
Look at it a different way. The wheel is clamped to the free moving belt. The thrust moves the belt along until rotation is reached when the hypergalactic locks on the wheels are magically released.
Either way, it flies. Even in Vancouver. You don't want Jack Layton to be stuck there forever, do you?? 😀

Poppycock I say. The question introduces no lag in the reaction
Ummm...
I would love for you to answer the question about how the plane is able to make progress on the belt if the wheels are not turning faster than the belt. I think this is the only stumbling block we have left and it was the eureka moment that finally brought me around.
And please, I am a Jack Layton supporter.

Remove the wheel/conveyor from your mind. It doesn't matter, and it is simply there to trip you into thinking the motion of the wheels/conveyor has bearing on the plane's movement. The wheels are only there to prop the plane up. The plane doesn't wait for the wheels to turn faster than the conveyor - it's acted upon by forces that aren't conencted to the wheels/conveyor.
The question is will the plane take off. Not whether the wheels will move faster than the conveyor. Whether the latter happens or not is irrelevent, but by connecting the two you hit a mental block that because one can't happen then other can't. That's the beauty of the question.
Vikash said:
Well the entire question hinges on that premise. If the wheels are not skidding then they are turning at the same speed. If they are not turning at the same speed then we have altered the question.
Remember Vikash, I was on your side at one point. The mental block was lifted and that's why I stand where I do. Introducing the thrust of the airplane and believing it can make progress over the belt without the wheels turning faster than the belt is where I believe your guys thinking falls short.
