how about posting your attempt so that we can see your approach. More than likely you made a mistake since all units should be homogeneous.

Here is a nice guide for creating a state space model of your system, which can be easily converted into a transfer function: http://www.me.cmu.edu/ctms/modeling/tutorial/statespace/mainframes.htm Dont hesitate to ask if you need further assistance.

OP, research the airfoils used by high performance gliders...

Appears to be dealing with harmonics. Notably spring harmonics. If so 'y' would be vertical or horizontal displacement.

This is wrong. There are more functions that have no analytical anti derivative than there are that do.

Hi again Mohdoo, reading your first set of equations, it seems you have used the exact opposite convention as I have stated in post 2. Again, The convention these books use for labeling is that you label your resistors in such a way that current flows counter clock wise. However, you use KVL in...

It is not unheard of, of people going this route. Although I fail to see why you would want your masters would be in aerospace - this is very specialized. You should probably stay within ME and go into the aerospace industry and see what its like first. Because an AE is just a specialized ME.

#1 Think about the pattern of Kármán vortex streets and the forces that would be created on a low density sphere. #3 Think about how lift is generated.

That's the thing, that statement and his equations imply mesh current analysis which needs KVL. What he does is imagine a single current in one branch and applies KVL to each component in a single loop and write the voltage of that component in terms of the branch current. Hence the use of I1...

If you are doing branch currents, or mesh analysis, You're using KVL to solve the system not KCL. The most common mistake most students make is use the wrong convention. You need perform KVL in a clockwise fashion (it helps to label your mesh currents accordingly). Moreover, you label the...

The forces used in the second and third terms of your equation for \delta_B are wrong. You have to take a cut at each point, draw a free body diagram and sum the forces for equilibrium

Use KVL and solve the differential equation. Either that or look it up. Since this is the homework forum I can't just give you the answer... We also need to see an attempt, if you have no idea what I'm talking about then you probably shouldn't be asking that question here.

What is the current solution to an RC circuit?

Simply use all the relations given. Its simply plug and chug nothing complicated. Then after you get an equation in x you just plug all your values in and get an answer. Very simple.
