Pics of various cars my friends and I have ... (they're links so that this page will load faster)

Here's some of our Crossle 55:

Here's a couple of my friend putting the new J&E forged pistons into his 1990 Shadow 2.5 Turbo's engine:

Nice pics,
I must say, thats a custom intake system you got on the viggen :D

:lol: Yeah ... doesn't give it any hp methinks (it's just a 3" cone filter strapped onto the MAF sensor) .. but it sounds reaaaaally nice.

"sssffffffffff-psshhhhh" <----- love that sound

Never noticed any performance difference with or without the cone filter. Even when I had it blocked off to only get cool air. Still didn't notice any benefit in hp. Mileage went up a tad though. On long freeway trips I average 34+ mpg! With 75% highway just normal daily driving it averages 28 ... which is quite nice!

Love the look on ricer's faces when they hear that sound too. :lol: You can hear it from a block or two away if it's quiet out. Veeerrry nice ...

very nice car and stuff dude

about that calculus, i'm wondering why you used the double prime of that to do it? how'd you know to do that? i know exactly how to get the answers you did too, i even did it out, lol, but about that last set of equations, with the gas and stuff, how does that work, i know the calculus part, but what did you plug in for numbers

I originally posted that in my friend's group as an answer to a question I challenged the group to do. But while the solution I saved (because I scanned it in), the problem was only on the group. I would just copy it now, but the group has closed.

Essentially it was a jet fighter refuelling mid-flight ... I assumed there were different concentrations of Methanol in the in-coming and existing fuel load. This is something the onboard computers sometimes actually calculate as a different fuel grade can lead to a diferent D.T.E. for the Jet. The rates of consumption in reality would be variable as well ... but I assumed constant fuel consumption ... at least during the re-fuelling.

The math is nothing horribly amazing, just some Diff-Eq ... only amazing part is I took that class when I was 16. :lol: I wish I had written down the initial conditions.

The other math stuff there was just something I did when I was bored. I'd been looking over some Aerospace grade metal specs and was wondering why our connecting rods are so huge from the factory. Turns out you don't need even one quarter the standard cross sectional area just to fight the tensile pull from the piston ... but the sheer forces during rotation contribute significantly as well. BTW Titanium has very little sheer strength, and is fatigue limited like Aluminum ... not too terribly great for a street car con rod. If you want lightweight con rods, get Steel H beam ... a good marraging steel alloy is stronger, even per pound, than the best Titanium ... and doesn't have a limited fatigue life.

Adrian~

edit: D'oh ... missed your question. :lol: I didn't use the double prime of anything. In the Methanol Jet fighter one. The double prime for the piston speed problem is obvious though. If you're referring to that one, the double prime represents the accelleration of the piston, as the single prime represents speed, and f(theta) represents position. But the Methanol one wasn't double prime.

dy/dt = rate of change for the Methanol Concentration in the tank. It is equivalent to the single prime f'(x). It was also a first order linear differential equation ... so it could be solved using the formula:

y' + p(x)y = Q(x) ------> then solving it using the "Exact Equations" method.

Which is what I did ... so I'm not sure where you're seeing the second integration? I just re-arranged the problem to fit the formula, integrated the formula (solving the differential equation), and then solved that equation at the appropriate initial conditions.

Adrian, your the only person I have ever seeen to actually use Diff Eq. after school. Quite interesting.

Haha ... I know ... I'm a nerd. What's really funny is I'm sooo not even into math. I play guitar and write music and poetry for pete's sake. :lol: That and photography ...

If you're bored here are some photographs I've taken recently:

i'll look at those pictures in a second, i don't want to forget what i wanted to say about the other message.

yes, i meant with the piston problem, not the methanol one, it is very impressive that you remembered that stuff and use it, and it's even more impressive that i know what you are talking about, except for the exact equations method, i haven't learned that yet, i'm in ap calculus, and have been since september, so i'll probably learn that soon.

post some poetry, i like that stuff.

i like your song dude, really good, and a lot of nice pictures, it sucks that the fires were so close to you, thankfully it didn't harm you. i have to say you're ex g/f's picture is better than your fave, sorry... :oops:

your sunrises suck dude, they aren't good at all, i'll take a picture of a maine sunrise tomorrow morning, if i get up in time, i hope i do, then i'll post it later on in the day.

you should take a picture of one of your sunsets.

~justin

another quick question: in the picture called the_fire_004, if you scroll straight down, you see a tree that has a really wide trunk and a little bush on top, are trees like that over there?? cause i think that tree is incredibly ugly in every way

damn - those pictures are good, a little better then me - not shitting you. Looks like you and I seem to enjoy taking scenary shots. I'll hafta send ya some of mine sometime - it helps when ya have access to good photo spots - u seem to have much more then I do. 8)

I do have some pretty decent photo spots. But they're all just around my house. :lol: And I rather like my sunrises! The first one was actually a sunset that I miss-labelled. :lol: If I lived closer to the beach I could get some better ones I surmise. And those "funny trees" are called Palm Trees ... they're all over this place. Much like Florida.

If you're in AP calc that's the intro to calc class. You'll go to "Methods of Integration" before "Differential Equations" ... sometimes Diff-Eq is bundled with Linear Algebra, but that may come before it as well. Depending on how your college is setup (the one you're going to go to) you may also take Multivariable Calculus before Diff-Eq most people do ... hard to say. It's a GREAT class though ... generally called "Calc 4"

Funny true story. I took Diff-Eq BEFORE the Physics 101 introduction class ... on the test I forgot the formula for the motion of a Pendulum ... so I derived it from basic facts using differential equations on the test. :lol: The teacher actually DEDUCTED points though because he said I was "showing off" ... *grumble*

If you'd like some poetry ... here are two poems that I wrote recently, and a couple not so recently, and may turn into songs:

Two recent ones:

The Shower

The warm water rolls down my skin,
And slowly washes away all sin,
Leaving nothing behind but to lament,
This cold room, and all time spent.

Washing sorrow down serpentine sewers,
Carrying away miss-deed, and miss-fortune,
I don’t feel cleaner, now that it’s left me.

“She’ll be back by dusk,”
I say to myself.
“To fill me with her empty lust,
Leave behind her trail of dust.”

And tomorrow,
Once clean yet again,
In her we’ll all trust …



Skin

It’s too late to fix,
Old wounds that won’t heal,
And I’d love to help you, dear,
If only I could feel.

You cut me deeply,
Scratched away my connections,
I thank you love,
For thickening scarred skin.

And I’d love to help you dear,
With your new affections,
But I’ve lost my depth perceptions,
With skin this thick, everything looks shallow.

I’m sure you’ll fix it,
Like you always do,
With a good band aid,
And your best screw.

Are your methods only skin deep?
Does it matter?
With skin this thick,
There’s nothing underneath …

And two older ones:

Midnight Peace

On the Beach
and in the air
the swooping swallows mourn

The sun they lost
through evening crossed
weakening lights transform

And the water and sand
sit hand in hand
in silent searching awe

Waiting at last
as in nights gone past
for the return of the golden thaw

sdrawkcaB gnioG (Going Backwards)

Returning when I left,
To check the time it's now before,
I did abhor,
The moment I first realized you were gone.

But now instead of forward,
I live backwards always treading,
Water dreading where I'm going,
Slowly living out a lie.

And I kindly step aside
As traffic moving right on by
Makes me lie upon the earth
So they can run me in the ground.

But as long as they don't take me with them,
And, I keep on moving backward,
I won't have to face what happened, just after today.


Enjoy!

Adrian~
