Turns out what I've envisioned has already been prototyped as found:

Still no idea how to set up the equations for it though
Hi there,
I'm currently working on a personal project, not really a homework question and didn't get an answer there so trying this forum. The idea is for a device that harnesses vertical motion via electromagnetic induction for the purpose of energy harvesting. I have built a prototype to...
What UR_Correct said essentially. Google "RLC circuits". Current oscillates between an inductor and capacitor via a resistor. Physically this is an oscillation between an electric field(cap) and a magnetic field(inductor). The resistor is an energy loss resulting in signal attenuation (with the...
You've pretty much got the TF. Rearrange the laplace you've done above so you get f/x = tf (factorise the left side wrt to X). From there, you can use MATLAB to analyse the TF.
MATLAB tools(look in help): tf, bode, ltview.
The time required to manually calculate the TF is trivial for systems...
There are two main reasons for changing from the time domain to the frequency domain.
1) It allows easy analysis of the frequency response of the system (if it's a filter, say)
2) Calculations are often required when passing an input signal through and LTI system. This is a convolution in the...
"An impulse response means your input is a unit step function, u(t), or one for t>0."
An impulse response represents the transient response of the system. It is the system response for a an "instantaneous" input decaying with time. The step response is more like the steady state response of the...
