Homework Statement Could someone explain how they came to this conclusion? http://hepweb.ucsd.edu/ph110b/110b_notes/node34.html Homework Equations I know how to get: ω1 dot + Ωω2 = 0 ω2 dot - Ωω1 = 0 The Attempt at a Solution I know euler is e^(i * t) = cos(t) + sin(t)*i but not...

http://i.imgur.com/TbYIHnb.png?1 So, if I have a pull up and apply a current source. How would I need to read/calculate resistance? V=IR I = 5V/8k = .0006A would result in a voltage drop of close to 5V Using a current source/Voltage reader I supply .0006A which should equate to ~5V...

thanks vk, going to give it a try with my module.

If I have a circuit similar to this: http://i.imgur.com/JaUGb.png I am reading in voltage as an input from Vin, when switch is closed, and am wanting to find out the unknown resistance R. Similar to dmm...what would be the best approach? Reading the voltage, calculate current to find R?

I have the calculations for the atm and gas force. I am not seeing how some get the formula, Fatm=F+Fgas+W. How do you come to this formula from the diagram? And then solve for F. Anyone.

Ok, well can you tell me a little more about the FO way, or at least some links so I will be able read more about this process.

this not be used to go 'off-roading'. This is more of a 'show and tell' type of work. The most it will probably do is drive circles in a parking lot. We chose this project as it was asked to be done. So, with that said, is there any ideas or input one might incorporate into this if they were...

It is a group design project in the 'brainstorming'/design stages right now...so we are going to go ahead with it. I was just wondering for additional ideas either related to the wireless network that will be associated with it dealing with bluetooth/laptop possibly or other ideas people had...

I posted this in the other section but didn't seem to get any replies and thought this would be a better forum for this type of question. Looking to brainstorm a little. Looking for some EE's or anything related to share thoughts. Trying to come up with some ideas to incorporate into a...

Looking to brainstorm a little. Looking for some EE's or anything related to share thoughts. Trying to come up with some ideas to incorporate into a wireless buggy(go cart). Will have a wireless connection between steering wheel and pedals, front/rear wheels. Will probably install sensors later...

You are correct. Even though I thought I double checked me answer before I posted the question, I just did the calculation and got -1.4138x10-20. This is more reasonable?

Well, using the ED formula mentioned above. I solved for mc = .98*9.1094x10-31 = 8.927x10-31kg and solved for ε=12.3*8.854x10-12 = 1.089x10-10F/m. Plugged those two equations into ED, and also h-bar = 1.054x10-34Js and e=1.6022x10-19C, I got the answer I mentioned above in my calculation.
