No tear drop is NOT IDEAL. Tear Drop is closest to ideal as a consequence of our needed compromises IE the need to put STUFF inside it.
Ideal is 2 dimensional line. ie zero frontal/base drag This is what erosion will do to an object IE erase it. the SHAPE of things eroded is mostly about density and type of material. ie one piece erodes faster than another portion etc..
EXERTING A FORCE IS NOT THE SAME DAMNED THING AS LIFT.
LIFT is a very SPECIAL SPECIFIC KIND of force exertion. Lower pressure on top via a venturi effect resulting in an effective higher pressure below the wing PUSHING or SUCKING the wing "up" toward the lower pressure.
THIS is lift. without ALL of those conditions ITS NOT LIFT.
its just pressure. its just a "force vector" nothing more.
your tear drop has PRESSURE has FORCE acting on it. It has NO LIFT.
winkosmosis gets it.
FORCE PRESSURE AND LIFT are not the same thing. its like saying a strawberry is red an apple is red so they must both be apples.
"If there is to be lift, there is also to be a change above the object being lifted. That change must be equalized below the object, meaning that higher pressure under an object, or lower pressure over an object, will create lift. Lift, in essence, is generated by a change in pressure... that would make pressure equivalent to lift, since they change linearly with each other, they can be transposed.
The above being the concrete case in physics, a force can only be counteracted by an equivalent force of opposing direction. This is to say, again, that lift still occurs at any tangent on the shape, but is opposed by the same gross lift on the opposing tangent, creating a net zero lift situation."
Christ. there are so many flaws in this statement where to begin.
your ENTIRE foundation is based on this statement.
"that would make pressure equivalent to lift"
without THAT statement nothing you say makes sense.
here is the problem.
ITS WRONG MAN. NOT EVEN CLOSE to being true.
PRESSURE DOES NOT EQUAL LIFT.
SHAKE UP A COKE. TONS of pressure right? any lift?
but "that would make pressure equivalent to lift" right?
NO.
Pressure is just pressure. nothing more nothing less. Pressure is "PART" of the lift equation but thats all it is. PART of it. they are not synonymous.
any more than a TIRE equals CAR. no a tire is simple a COMPONENT of the car. Pressure is simple a COMPONENT of lift.
without the "rest" of the components you don't have lift. Just like if you only have 4 tires sitting in your driveway YOU DO NOT HAVE A CAR.
until you have the rest of the pieces needed you don't have a car
until you have the rest of the pieces needed you don't have LIFT.
