    Undergrad Examining DC Signals & Batteries: What's the Difference?

    1.No problem, solved. 2.I can't say that I understand fully either. But I can say that it's much faster than emf because can't see the propagation delay between electrolytes. Distance between them is 6cm so it would take 200ps minimum, I have a scale of 40ps on my scope but still get a phase...

    Undergrad Examining DC Signals & Batteries: What's the Difference?

    That's what I was talking about but didn't wanted to push more after I observed that I could'nt express myself to majority efficiently. The main phenomena responsible is; http://wikipedia.org/wiki/Proton_coupled_electron_transfer And it's being driven sequentally, but they overlap as you say...

    Undergrad Examining DC Signals & Batteries: What's the Difference?

    I am sorry, trying again. When you connect a resistive load across terminals of a battery, a direct current will start flowing ; meaning specific amount of electrons propagating per crosssection but how about the repetition rate of this process? Inside the battery ions are being transported...

    Undergrad Examining DC Signals & Batteries: What's the Difference?

    Smallest possible charge is 1 electron thus there should be some sort of rate to generation/conversion.

    Undergrad Examining DC Signals & Batteries: What's the Difference?

    If you study a DC signal under an appropriate scope, you can see the switching transitions ; a pwm signal. But if you examine a battery, no matter how high temporal resolution you reach, you see a dc signal. What might be the explanation for this? electrons are being generated by a chemical...

    Undergrad Rotational speed due to gravitational pull in earth's orbits

    Hi All, Assume we have a package that we want it in an orbit with highest possible speed. In which orbit (low,mid,high) the package will rotate faster ? Due to smaller distance, low Earth orbit should allow more speed but there is also more air friction there. What would be the mathematical...

    Mathematically modelling a mechanical system

    Thanks for all suggestions and sorry for late reply. State model will require very high amounts of sampling points to reach a certain precision but it seems that it's the only way of doing actual calculation. Rather then defining/generating each point I want the output derived from a time...

    Mathematically modelling a mechanical system

    I considered trying to write lagrangian of it but no luck. Programming is easy no problem,i want to write equations to describe the system(continious not discrete).

    Mathematically modelling a mechanical system

    I want mathematical modeling not visual. That indicates gear positions, speeds, radius and every other possible variable.

    Mathematically modelling a mechanical system

    Hi all, Consider a simple gear system. I want to learn to model this system and write equation for it that any information/state regarding system can be extracted from. thanks
