The wings help the airplane to fly?

Answer 1

Sort of, the engine provides thrust so I suppose they help the airplAne to fly but the wings play a huge part in flight. Of course the presence of wings help the plane to fly as it prevents it from crashing because it creates an opposing force to gravity called upthrust. But the shape and angle of the wing is also important. For a plane to fly you need to create a force called 'lift'. Lift is created when air goes over wings and to do so it has to speed up to achieve the momentum that is needed to travel that fair. The higher speed of the air above the wing means a lower pressure underneath the wing, and therefore lift is created. Now if air has to speed up to go over the wing, then to get more lift the air needs to speed up therefore there has to be a greater distance for the air to travel. This means that the larger the wing and the more curved the wing, the more lift is created as here is more distance for the air to travel. Also the steepness of the wing affects lift but there is a catch. The steeper the angle of the wing according to the body of the plane, the more lift is created as there is a greater distance for the air to travel however there is a critical angle which is 30 degrees. This critical angle means that yes, the steeper the wing the more lift is created however only up to a maximum of 30 degrees or else no lift is created. I hope this helps :)
