... it is said that the conveyor belt compensates for the advancement of the plane, that's all!

Precisely, it does not compensate for anything at all since the wheels-carpet assembly does not constitute the right reference point and only "smears" you with errors ... : Wink:

Frankly, I stop debating with such bad faith! I thought you were more open-minded than that! : Evil: : Evil: : Evil:

The error is you who is inside and well and on 2 points: if you neglect the friction of the wheels then the lift cannot exist! So you are making a double mistake!

I proposed a compromise solution that should have intellectually satisfied you and exni and you spit it in my face? Seriously?

Spin a Boeing wheel at 1 rpm ... we'll see if the power of its internal friction is not counted in MW ... : Cheesy:
If 1 Million RPM is not enough for you goes to 100 M ... OSEF since there is no limit in the statement!

There's nothing worse than a donkey who doesn't want to move forward!

If we calmly resume and admit the statement, the plane will accelerate and the carpet too (at speeds not possible!) And the plane will take off. More , if we assume that the belt prevents speeding up from the ground (for no other reason than is what the one who wrote this glue claims!), then the plane will stay where it is ... : Mrgreen: It is this last assumption (underlined) which is absurd ... : roll:

Oh cow that's it !!

It is absurd for two reasons:

a) A conveyor belt can stop a plane in a world with friction but it is technologically impractical given the different orders of magnitude

b) A conveyor belt cannot stop an airplane in a frictionless world but in a frictionless world there is no lift so planes either

But a statement must be accepted! Physically and mathematically this problem is not absurd and is very interesting: the proof that we spent dozens of messages and cumulative hours there! : Cheesy:

Him and his forum, it boils down to that
