Hi all, I am trying to determine what is the maximum number of amps I can charge 4 batteries that are in parallel and series ( 4x12V batteries) to produce 24 volts. I have the specs on the batteries and everything but can not seem to determine how many amps they can handle when being...

Yes... I also have done my fair share of math. Allergic to bounded intervals? ... I don't see how this relates to the discussion of thinking an infinite sized plane is "simpler" than a finite plane. I didn't think we were talking about an infinite amount of numbers between any 2 numbers...

I have a hard time hearing people saying that infinite is simpler. If one just thinks about what infinite means for a few moments, you can realize it is beyond our comprehension. Which I think means is not simpler than a printer sized sheet we deal with everyday. It may sound simpler to...

Don't listen to this ridiculous paragraph. An engineer doesn't have to get a PhD in order to be a successful engineer. You also have some nerve calling an engineer that does not have a PhD a fake engineer. Judging from this paragraph, this guy has no idea what an engineer is or even does...

Radii is the plural of radius...

I don't think it's irrelevant, I like to know all the values and what they are if I am going to use an equation. I just find it hard to believe, Axeman, you don't know what \epsilon_{0} is since it seems you are in an electricity class.

Are you familiar with Hess's Law? Rearrange the bottom 3 equations by modifying them and combining them to make it look like the unknown.

What do you think the laser being built at lawrence livermore is for, fusion? :zzz:

Must just be an arithmetic error. I don't think it is a radian/degree issue.

anytime :approve:

Well... how do you relate force and acceleration...

Also, just looking at what side the window washer is on, you should intuitively determine which side will have more tension.

Just take the moment at each end. Each one is only one equation one unknown.

... my comment was directed to the original poster as he said he got an answer of 2 and assumed that was the final answer. Which would not be the case even if 2 was what the right side came out to be due to the fact he took the log of the problem in the first step.

Also I am not sure that you know that when you take the ln of this, you need to take the ln of the other side of the equals sign. So just assume that it equals y, then the answer is ln y = 0, which would be 1.
