Explain how an airplane wing creates "lift". Diagrams may be used in the explanation. For the Law of Sines, state the formulas, explain them in your own words, and draw a diagram illustrating one of them. We are given the diagram below and asked to solve for T_1 and T_2. Explain,...
The wing must produce lift equal to this load factor if altitude is to be maintained. It should also be noted how rapidly load factor increases as the angle of bank approaches 90°. The 90° banked, constant altitude turn is not mathematically possible. An airplane can be banked to 90°,...
Explain how an airplane wing creates "lift". Diagrams may be used in the explanation. Consider the diagram below and choose the expressions that are correct. - 0 = E1 - E2 + i1R1 - i2R2 - i1 + i2 = i3 - i1 = i2 + i3 - 0 = E1 - E3 - i3R3 - i1R1 - 0 = E2 - ...
