Glue would significantly increase the friction so yeah that would have an effect. That would make the wheels not free spinning, just like applying the brakes.I guess that force against the wheels is determined by the coeffecient of friction between the wheels and the treadmill.
Say the belt of the treadmill was covered in glue. It would make a difference because of the adhesion between the tire and the treadmill. Friction also works as a cohesive force. That is why we stick to the floor in the gym instead of falling down when we try to stop real fast.
I said that too, I dont think it was on this site too. I said "if they can keep it straight"Can't view streaming media at work. But the question in my mind is this:
Does the fact the belt is spinning backwards increase this cohesive friction to a degree the thrust of the propeller cannot overcome it.
With a strong enough engine, it can break free if the wheels where bolted to the ground.
What I personally think will happen is the plane will either fly too fast and run off the ramp or too slow and fall off the back. Yes, it is a quarter mile long though....but it also has to be straight and level throughout, or the plane could fall of the sides.
