Thanks. That does at least confirm the relationship of I to a.

I forgot this can probably also be done using energy equations, so I forgive me, as that would have been a way I could check my results. If someone has that solution handy, that would be great as well. I will attempt that, but it will likely take me some time to brush up on those...

Hello all, and forgive me if I'm making newbie mistakes as I haven't posted here much. I realize this appears to be a homework assignment, but it is not. I am trying to develop an easy method for determining the actual moment of inertia for real wheels, for bicycles and other vehicles. I...

Well, after going through quite a few data sheets I ordered some LM6142's. Turns out, the hardest feature to get, anymore, is the 8-pin dip footprint. Making stuff at home is only going to get more difficult, apparently. But Digikey still had some 8pin dip versions in stock...

I thought I found it with this one, but realized I needed a faster slew rate than I first thought (for the current project). I probably need more like .5v/usec. This one is .07v/usec. http://cds.linear.com/docs/en/datasheet/14901afd.pdf Everything else about it sounds good.

Thanks again, I did find a Maxim product line with almost exactly the internal protections I was looking for, but unfortunately, the line is also "Micropower" which means very low output (less than 1mA). It also only handles 5v as the supply. But it makes me hopeful something is out there with...

Thanks, that is a handy little page indeed.

Hi all, I realize I'm asking for the world here, but google hasn't been very helpful. I've found a few candidates with some/most of what I need, but wondering if there is some holy grail op amp out there that everyone is using. I'm growing tired of making work-arounds for the LM324's I have...

Thank you very very much! :) and I guess I put this in the wrong forum. Sorry about that.

I finished editing the post above, with my question.

Please forgive me as I may have to edit this post to get the equations to show properly. I am doing some work with AC circuits and part of one of my phasor equations has this in it: \frac {2i} {1+cos(θ) + i sin(θ)} - i , where i is the imaginary number \sqrt{-1}. However, knowing the...

Hi all, this is my first post. I find a lot of conflicting definitions of damping factor, damping coefficient, and damping ratio on the internet, and in some textbooks, when related to RLC circuits. Sometimes I see the neper frequency described as the damping factor or damping coefficient...
