Simplified: Equations of Motion of a Quadcopter

AI Thread Summary
The discussion focuses on the complexities of understanding the equations of motion for a quadcopter in an x-configuration. Participants note that while some resources exist, such as a specific academic paper, they can be difficult to comprehend, especially for those without advanced mathematical backgrounds. The importance of understanding Denavit-Hartenberg parameters is highlighted, as they are essential for dealing with the quadcopter's degrees of freedom. Simplifying these equations significantly may not be feasible due to their inherent complexity. Overall, the conversation emphasizes the challenge of making advanced topics accessible to high school students.

Hello! I've been looking into the equations of motions of a quadcopter with an x-config. The only thing I've found was http://www.inase.org/library/2014/santorini/bypaper/SYSTEMS/SYSTEMS1-07.pdf, but it seems complicated. Could someone explain the equation of motions, and how they were arrived at? Also, is it possible to simplify the equations to something someone in high school could understand?

Thank you in advance

How simple would you want it ? There are a number of degrees of freedom you have to deal with, whether you like it or not.

The article is only a part I of an intended series ... (not followed up since 2014 -- and I grant you it's hard to read -- partly because of the imperfect english)
Did you read up on the Denavit Hartenberg parameters ? I think you'll need the mathematical formalism to do anything non-trivial in this area. It's simply not that easily simplified...

Funny. I google and find a lot more.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
