Plane falling from air, mechanical physics, need push in right direction

Click For Summary
SUMMARY

The discussion centers on solving a mechanical physics problem involving a plane in steady flight, specifically focusing on the forces acting on its center of gravity (CG). The participant has modeled the problem using triangles but seeks guidance on how to initiate the solution process. Key advice includes creating a diagram to visualize the forces and being cautious about simplifications in aerodynamics that may differ from standard textbook definitions.

PREREQUISITES
  • Understanding of mechanical physics principles, particularly forces and motion.
  • Familiarity with aerodynamics and the forces acting on aircraft.
  • Basic skills in diagramming and visualizing physical problems.
  • Knowledge of steady-state flight conditions and their implications.
NEXT STEPS
  • Study the principles of forces acting on a center of gravity in aircraft.
  • Learn about steady-state flight and its characteristics in aerodynamics.
  • Explore diagramming techniques for visualizing mechanical problems.
  • Review aerodynamics textbooks to understand common simplifications and their effects.
USEFUL FOR

This discussion is beneficial for students in mechanical engineering, particularly those studying aerodynamics and aircraft dynamics, as well as educators seeking to clarify complex concepts in physics.

That is the problem that I am trying to solve. It is simply a practice question but I want to make sure that I am doing things right and that I am prepared. I understand the concept of this problem and have modeled the problem on paper with triangles. I just don't understand where to get started. I am sorry if this is vague, but even the smallest hint will probably help because I have done this work before two years ago in high school, but I am at university now with a mediocre lecturer and unfortunately some of the material isn't clicking like it should.

Thanks for any replies!

It may help to make a diagram with all the known forces acting on the CG of the plane and to consider what happens when the plane is in steady (non-accelerated) flight.

The problem text seems to introduce one or more simplifications over the usual definitions in aerodynamics, so be careful if you refer to a textbook in aerodynamics.
