Question
What is a free body diagram? What are they used for? How are they useful for the structural analysis of an aircraft? Explain with use of at least one diagram and at least one example, no more than one page. Attach your answer as a separate one-page document (pdf) with your spreadsheet submission Tip: Treat this as an opportunity to get feedback on your discussion skills, considering this will form a significant part of your assessment for the whole course. Don't just dump in what you find in a Google search or in a textbook. See if you can answer it in your own words as best you can, with a diagram that makes sense to you and helps illustrate your argument)Explanation / Answer
Free body diagram
Free body diagram is often considered as a useful aid for solving a statics problem. It is a convenient method to model the structure, structural element, or segment. It simplifies the complex problems by treating them as simple as possible. The figure given below shows a street lamp and how a FBD is conceived from the actual picture.
FBD is a very essential tool in case of aircraft analysis. As the aircraft analysis often composed of several force and moment components, it is difficult to understand the problem without using FBD. The complex structure of aircrafts is also a reason for the requirement of FBD in analysis of aircraft.
