That makes sense. Thanks for setting things straight and informing me of the standard current conventions used today.

Oh, ok. Does this mean that currents ,in reference to an electrical perspective (as opposed to a Physics perspective), always travel from + to - in DC and AC currents, or are there exceptions?

Homework Statement When reading about directions of magnetic flux in relation to current flow on pages 6 to 8 of http://www.free-energy-info.tuks.nl/Non-Ferrous-Magnet.pdf , I found that in figure 11 the current is traveling from + to - terminals, while in figure 12, the current flows from - to...

Thank you! That helped me understand more.

Yes I agree with you completely. I must find the true significance of dotted and double dotted x to understand more. Another note, after more searching, I found that the gear ratio can also be expressed in Radians per meter, so Rad/m most likely refers to that. It is less plausible for them to...

If It was wrong of me to post that diagram could someone please notify me.

here is some info from post 1 and additional info. The system is a floor tile that generates electricity when stepped upon. where x is the position and V the voltage across the load resistance. k= 150000 N/m The spring coefficient. D=10 Ns/m Mechanical damping Kt = 0.0728 Motor constant...

Once again, this paper has defined the Suspended mass (without dancer)m as 35kg and the estimated mass of the dancer between 70 and 100kg. I wish to find how the Power, Current, and/or Voltage may be affected if the mass of the dancer was higher or lower than estimation (70-100kg). Is it...

It is on page 4 http://www.researchgate.net/publication/224505926_Human-powered_small-scale_generation_system_for_a_sustainable_dance_club or http://ieeexplore.ieee.org/xpl/abstractAuthors.jsp?tp=&arnumber=5075243&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D5075243...

would that convert to \ddot{x}=\dot{x}, (15000/m) \dot{x}-(10/m)-(1601.6^2/84.6m)\ddot{x}+1/m=\ddot{x} and V= (240240/169.2)\ddot{x} I feel that I have done something wrong in the simplification of the matricies, could somebody assist me in finding my error?

.

Ok, Thank you. I am beginning to understand. I just need to engage in a bit more self study to understand more of the the mechanics behind the mathematical concepts. I realize that I was unable to display the equations. In the future, how should I input my formulas to make them visible to others?

Homework Statement I am trying to understand what [x^. x^..] means, and information regarding the vertical format it is in . Can someone please help me understand, or refer me to a website that can aid me. Thank you!The system is given by...
