I don't think Calculus understands knock...

Nearly did a spit take while doing my math homework. I know it's a theoretical situation, but I think we all know that the efficiency would be zero after the motor came apart... :rofl:

i think your getting your english and your math mixed up

english uses letters
math uses numbers
 
Excluding catastrophic failure,
What I want to know is how is "c" determined
I mean say that you have a 10/1engine v1/v2 would be 1 to1/10 or 10; then

E%=100 x 1 -{1/10^c}

If I choose .5 for c, then E= 80%
If I choose 1 for c, then E=90%
If I choose 2 for c, then E=99%
If I choose 3 for c, then E=99.9%

But say you have a 8/1 engine,then v1/v2 would be 1 to 1/8= or 8; then

E% =100x 1-{1/8^c}
If I choose .5 for c, then E=75%
If I choose 1 for c, then E=87.5
if I choose 2 for c, then E= 98.44
If I choose 3 for c, then E=99.8%

So it seems like c would have to be less than 2 for sure,
and possibly less even than 1
but greater than 0

So what is"c"?

Click to expand...

That's the point of the equation, is that when you graph it, it won't go over a y-value of 100 (because you can't have a 110% efficient motor)

Isn't that a "probability" equation??

Yeah... Probability of engine failure!
(It's actually a limits problem... I still question how the hell I do it sometimes)
 
Stop. Do not do any more Calculus. Many moons ago when I was doing physics equations in preparation for operating reactors my mind fried. I never recovered.
 
Professor Rochelle gutierrez says algebra, and geometry are racist. It promotes white privilege.
I must be ok, since I sucked at math, but the rest of you, well.......
