I was just wondering if this was a valid approach to state space from two second order equations to four first orders. I appreciate the input and if this is valid then all is well. Thanks! Ah yes , most definitely ODE's, I must have mis-typed the 'O'... twice.

I'm trying to 'solve' two coupled second order ODE's with the intent of putting them in state space. My specific problem is more complex and includes additional equations which are irrelevant. Essentially I can solve the problem if I know the solution to this. x1 and...

I'm trying to derive the equations of motion and state space as well as the transfer function for a system which has two mass spring damper systems stacked on top of each other. The system is base excited. I attached a pic of the system

I'm trying to find a solution to a system in which a clamped free Euler-Bernoulli Beam system rests on top of a mass-spring-damper system. The MSD system has nonlinearities in both the spring and the damper and is of the form:
I have extended the nonlinear restoring force to its 3rd term and...
Hey all,
I'm stuck on this problem and not sure how to proceed/if I'm in the right direction.
Problem: One reference frame N sits at the origin (inertial frame) while another frame, B, describes a disk rolling on a circular ring about the other frame. Picture below
(A) find the direction...
Sorry for the extended absence, busy with other courses and had to order a few components. Anyway, the circuit tested fine so I appreciate the help and input from everyone. The new issue is implementing into practical use. I have a few power management circuits that I'm currently looking at...
Thank you all for the help and taking the time to test the system. You are correct in that I was pulsing at too high a frequency and have not included a limiting resistor. I will make adjustments and test it myself on Monday!

Hi All!
A little background info. I'm working with cardiac pacemaking devices with the overall scope of implementing piezoelectric energy harvesters into the devices. I'm in the initial stages of research and development.
Okay, so this is my conundrum: I have an output pulse circuit as shown...
