Drag Force - Definition, Principle, Discovery, Formula, FAQs
When a solid body interacts with a fluid, drag force is produced on the solid body.Drag forces are not created by any force field. In order to experience a drag force, the object has to come in physical contact with the fluid medium.

A wing with an elliptical planform is flying through sea-level air at a speed of 45 m/s. The wing loading W/S = 1000 N/m^2. The wing is untwisted and has the same section from root to tip. The lift curve slope of the section, mo, is 5.7. The span of the wing is 10 m, and the aspect ratio is 5. Find the sectional lift and induced drag coefficients. Find also the effective, induced, and absolute angles of attack. What is the power that is required to overcome the induced drag of the wing?
