Answered You can hire a professional tutor to get the answer.
1. How can a pilot maneuver an aircraft that is experiencing negative g load? Are there conditions that create this without the pilot input?
1. How can a pilot maneuver an aircraft that is experiencing negative g load? Are there conditions that create this without the pilot input? Think of what happens on a fairground ride.
2. Why does maneuverability point change as the aircraft flies at different altitudes?
3. Why do fighters have additional envelopes? Give an example where this may be needed.
4. 'I' beams are used in the ordination to show the shape in an 'I' form. What happens when they are used in the 'H' form? How is the stress distributed and would it deflect as much or more? - justify.
5. Modern aircraft have several spars (Beams); how does this make the wing stronger to resist the weight of engines?
6. Why is there zero stress at the neutral axis and will this change when the upper wing experiences compressive stress and not tensile stress?
please explain
