Alright you bunch of degenerates. Solved and explained. You don't have to like it, you don't even have to agree with it. Physics doesn't require your approval in order to function the way they do. The riddle is designed for you to bicker. Some of y'all have zero understanding of Aeronautical Physics.
Will a plane on a treadmill take off or fly? There isn't anymore details than that. So, people insert their own terms and understanding to answer their perception of the question.
So, what do we know? Well, we know we have a treadmill, and we know we have an airplane. That's it. No other factors. No speed of an airplane, no speed of a treadmill, therefore as we insert our own determining factors that comes from our perception of the question, we answer it from our own perspective. But is that enough?
The only one of you who nailed it, is Deceptive. Let's breakdown the characteristics of sustained, controlled flight.
In order for any winged aircraft to achieve flight, you need 4 forces. Thrust, lift, weight and drag. Yes you need all 4. Not 2, not 3. All 4. Thrust alone, without the other 3 doesn't mean diddly squat. All 4 must be present to have ANY lift and hope sustained, controllable flight.
Again, we do not have enough information to come to a conclusion, so let's take what we know. There are 3 possible scenarios with 3 possible outcomes.
Scenario 1) There is a pane on a treadmill. As the plane increases it's thrust, the treadmill equally increases its speed. In this scenario, there is no lift. Lift is determined by the amount of air that passes over and under an airfoil. Air needs to pass over the airfoil to create negative pressure under the wing which creates one of the forces needed, Lift. If the airplane and treadmill are matched in speed and thrust, there is no wind or air generated to create negative pressure. Scenario 1 equals no flight.
Scenario 2) There is a plane on a treadmill. The planes thrust is less than the speed of the treadmill. In this scenario, there is not sufficient air or wind to generate negative pressure on the airfoil to produce one of the 4 needed elements to produce lift off or flight. Scenario 2, the airplane moves in reverse. Due to the speed of the treadmill is greater than the speed of the airplanes thrust.
Scenario 3) There is an airplane on a treadmill. The thrust of the airplane is greater than the reverse speed of the treadmill. If enough speed (thrust) is achieved, then the air passing above the airfoil will generate negative pressure under the wing and produce lift. Scenario 3, the airplane will achieve flight.
You do not have to like it. You don't have to agree with it. The physics won't change because of your feelings.
Feel free to read The Airman's Handbook of Aeronautical Knowledge. Here is a link for your enjoyment. This was the book I had to know front and back to pass the Federal Exam. Enjoy.
