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 ...
It is this last assumption (underlined) which is absurd ...
Imagine an irresistible force that meets an indestructible obstacle, what do you think will happen?
Almost 3 years later...I'm doing it again...because it's the period of knots in the brain (and who here likes that...
)
I rephrase the solution:The correct solution is for the plane to take off (almost) as if nothing had happened. because a treadmill of an airplane on wheels (which cancel the friction on the ground, therefore on the carpet, at uh like "100-X" %) cannot prevent this plane from moving forward because it transmits its power by pressing on the air and not via its wheels...the X% will slightly slow down the plane which will take a little more distance to take off...
Think of a bike on a treadmill: push it by hand on the frame, it will move forward almost as if nothing had happened (with friction X near the wheels). It's the same here.
If the power was transmitted by the wheels, like almost all land vehicles, it would be different... the same with a plane that brakes (wheels locked), on skis or without wheels...
The statement is therefore based on an unrealistic, misleading and twisted hypothesis...but that has already been said!
