Hi--from the acceleration signal you should be able to reconstrunct the loal diplacement as function of time. Then, you could do some FEM calculations on the structure, maybe checking for fatigue failure.

think that the energy conservation you write about, which in your idea gives no real explanation about the cause of the motion,
\frac{1}{2}\dot{x}^{2}+mgx=const,
is instead exactly equivalent to the equilibrium relation
m\ddot{x}=-mg
as can be proved by deriving the en. eq. in the time once...
Hi-
a)I don't understand the question. What's the difference between highly compressible and almost uncompressible fluid about pressure definition? none, as in every other substance
b)if you think that pressure decrease at section where velocity increase (at same heigth) as the only way to...
great.
In the latter case you are supposing to know the equilibrium state, and you say that the force can be applied anywhere (but always perpendicular? I'll suppose so) along the mechanism.
That's an interesting point.
I would do some few considerations first.
We'll consider a...
Hi-
1. The time it takes for increase the kinetic energy of the flywheel mainly (but not finally) depends on the characteristics of the energy supplier (your GSX50) and utilizer (in a direct coupling). Write down the energy balance and you will get the dynamics (and then the time). But direct...
Hi- It is not clear to me what you mean for long/short arm.
Anyway, it seems to me that the reaction of the torsional spring k1 can be simply obtained requiring the static (is it a static structure?) equilibrium at rotation centered in the k1 point for the complete structure. In that case, as...
Hi-
for volumetric strain distribution I suppose that you mean the trace of the deformation tensor. But in principle it is not enough to reconstruct the displacement field, and then the bending. What about beam constraints? Is this volume expansion/contraction due to temperature variations?

Hi
if you know that leak occurs at tank sealing, it should be sufficient to compare the viscosity of the hydrogen and of the gas you are supposed to utilize. The leak (dot_q) decrease proportionally to the viscosity (eta) as dot_q propto 1/eta.

Hi
2)FSI at (e.g.) hip joint is called thin film lubrication. It it substantially different from classical (e.g., as you write, biomedical heart valves) FSI since the size of structures deflection is comparable with the same size of the film thickness. The topic is quite well studied by not...
Hi
It is not really clear to me the question. You mean the spin motion (rotation of the ball with rotation vector parallel to the segment connecting the two centers)?
