Engineering - October 2007

my friend is a kite expert. He is good at making the usual thread/rope kites. But one day he said that with the help of a toy aircraft engineer, he could build a remote controled kite.
is he just kidding me ?

I did few basic experiments with NI ELVIS in my school.
And I realized I missed something. It's about DMM.

What if I set the range of resistance less than actual resistance.
ex. If I set the range of resistance as 30k ohm
and the resistor is 300k ohm, what would I see in the screen?

I'm just curious because I know you do have to be EPA certified to use refrigerant, so how does that work with students at a HVAC class in college studying to be hvac techs.

I can't decide what I want to do with my civil engineering degree when I get out of school... As far as I know I can go into design, or I can go into something like field work or construction management. As far as I see, there is more money in design, but I think I'd enjoy being out doors on projects more. I would like the design to, but just not as much. Does anyone have any opinion on this situation...is there money in managing out in the field?

What would

y = -x
y = -x - 4

We're learning to find the distance between parallel lines. My teacher tells us to pick of the y's and she always does the top one, but it's just -x how would that work?
