Hi, Do you guys know of any good Power systems and machinery book for understanding the fundamentals and applications? I found these two books but I can't tell which one is actualy good, I don't know much about the subject. So far I found these two ...

Thank you that's very helpful !

Hello, Can you suggest me some good Math books about Fourier laplace transforms, convolution, transfert functions and stuff ? Because all I have right now is some crapy math notes and an electricity book that doesn't mention anything about math theory. I tried google but I really don't...

Hmm. looks like it's more complicated than I thought, I should consult a professor because I didn't get to these notions yet. I'll take good note of all that. Thanks.

The reason I was asking is because I find it weird that nobody mentioned this ferrite rode loop antenna not even the graduate student, and we really need something small. For directionality, I know that it's not easy to shield the signal at that frequency, so we're going to make sure that the...

Exactly. For the circuit the technician of the team was talking about that the other day I think(AM radio receiver circuit) I got lost with filters and stuff sorry.. http://www.circuitstoday.com/tag/radio-receiver-circuit In this website for example, they state that a 100 cm metal wire should...

Hi, We're trying to build a simple antenna that's able to pick up a frequency of 457 KHz from a maximum distance of 20 metres. I'm totally new to this stuff, so I looked up the yagi antenna and some formulas used to determine the length of the antenna, but the results I got were huge...

Yeah that's what I thought when I saw the question, but then I said maybe I'm wrong since the problem has 3 questions : a)what's the minimum V b)maximum V c)calculate the value for r=7 It's a instructor made problem... :p Thanks for the help ! and I guess you will often see me in this...

Normal and gravitational force(mg) Usually we want to know what's the minimum velocity so that the can make it (N>0) but here I don't understand the question, what happens if it's going too fast ? will the rail break ? if yes what does that mean ?

Homework Statement What's the MAXIMUM velocity the roller coaster should have at pt A in order for the passengers to stay in contact with their seats ? calculate the velocity for r=7 It kinda looks like this [img=http://img94.imageshack.us/img94/6994/image39.gif] Homework Equations...
