Q: Would the plane take off?
Submitted By: thewise1, 309 days, 2 hours, 18 minutes ago
A plane sits on a giant treadmill capable of spinning the opposite direction of the plane, as fast as the plane is required to go in order to take off.
The giant treadmill is, for the sake of argument, 5 miles long.
The wind is N @ 1mph.
The treadmill accelerates to the same speed that the plane moves forward and can magically keep its speed exactly the same as the plane.
Can the plane take off?

Wheel speed makes no difference. The thrust from the engines is identical to a non-treadmill scenario.
The plane would take off.

The plane must generate lift in order to take off. This is obtained by moving down the runway. You can have all the thrust you want but if you're stationary, you're not going anywhere.
