When a plane is in flight, the entire weight of the aircraft is essentially supported by the wings. To help you with this problem, it will be best if you visualize holding a model plane in the air with your two hands located roughly about half way along each wing. For this problem:
1. Determine the air pressure (psf) acting on the underside of the wings which will just support the fully loaded Antonov 225 Cargo Plane in flight if the plane and its cargo weigh 650 tons. (The sum of forces in the vertical direction must be exactly equal to zero if the plane is in level flight; otherwise, it would be falling or rising);
2. Draw a free body of one of the wings; and
3. Determine the equivalent force system which would replace the distributed wing load;
4.Determine the reaction forces which occur at the junction of one wing and the fuselage. (Note that the wing is cantilevered off of the fuselage with a fixed connection.)
