My roommate watches it, so I am forced to. I do find it mildly entertaining, but I've only seen maybe a season's worth of it so far, so maybe it will grow old after a while. I never watched it previously.
Scrubs Musical Episode Issues

Ok, so this is driving me freaking CRAZY. I'm sitting here watching the Scrubs Musical Episode on Comedy Central right now. Proor to this I've only seen the musical bits online a few times. I'm sitting here watching the opening song, and I couldn't figure out what was wrong. Then I realized that it seemed to be going a bit faster than the one on YouTube. If I listened closely, I could hear the tempo speeding up and slowing down. I guess it was done on purpose to fit it into a half hour slot, but the tempo wasn't consistent and it really REALLY drove me nuts. I asked my roommate and he just insisted that I was making it up but I SWEAR there was something messed up with the musical bits. I don't know why they'd have to speed it up - it was MADE for TV. If anyone can explain why they did this to me, I'm listening. I KNOW that there was something going on - I just don't know why! It got so ANNOYING after a while!!!

So was I right about the whole two cars drafting then? That's pretty sweet. I feel smart, lol

I've been running at 100 degrees. I don't have a widescreen monitor, so i need a wider FOV to make up for it. I USED to use 100 degrees on two screens too though. I just prefer to see as much as I'd see in real life than worry about how distorted it looks.

Quote from Dark Elite :The tilting and curving of the wing will slow the air down in the areas that are curved or exposed - but seeing as the air will either pass straight underneath the curved area or along it, air going underneath the wing actually won't be affected by the curve very much, will it? So the air underneath remains pretty fast, whilst the air above slows down quite considerably - thus gaining a higher pressure and pushing the wing down. Then you have the effect of the air pushing against the wing as well, but whether this is the same effect, another effect, or just drag, I'm not sure.

Have I finally got this the right way round now?

Yes that's better. In your Post #22 I was like FASTER AIR IS HIGHER PRESSURE?!?!? NO WAY!!

This is the way I see it:

Quote from 510N3D :Right, are your sure you understood the context in which i made this statement correctly?

Yeah. I figured that was what you were talking about, but the fact that you wrote "I think" made ME think that you weren't 100% positive, so I was simply agreeing with you

Quote from Dark Elite :I'm now completely stuck between deciding whether air moving more quickly results in a higher pressure or a lower pressure. Air moving more quickly means that air doesn't need to be in the same place for as long, resulting in a lower atmospheric pressure, but also that more air hits the surfaces of the wing, resulting in a higher pressure on that. Which effect is greater?

Better find out before I go any further on this one

Sam

Well, air moving more quickly parallel to the surface would result in a lower pressure, pulling it up. If the air is moving more quickly at an angle less than 180 degrees then you start to get the effect of the air pushing back down on the wing. My guess is that there is a critical angle at which point the air hitting the wing overpowers any effect of negative pressure. Especially since as that angle gets larger, the air isn't really traveling as fast over the wing anymore. Wonder what that angle is...?

Quote from Dark Elite :Air travelling under the spoiler isn't necessarily a bad thing - so long as it is slowed down. Air moving slowly underneath the spoiler surface, I believe, results in a lower pressure, and so the spoiler - and the arse-end of the car attached to it - tries to move down to occupy the lower-pressure air. This effect is increased by the faster-moving air above the wing creating higher pressure, as the wing is now under a double effect - high pressure above pushing it down, and low pressure below encouraging it to move down.

Well, I don't know much about how wings are set up, but assuming that the air under the wing IS moving faster (either due to the shape of the bottom of the wing, or the shape of the car making that air move faster) it WOULD create low pressure pulling the car towards the ground. But at the same time, that's simply going to pull UP on the car's body under the wing, so unless the air under the car's body is moving even FASTER , it kind of cancels out that effect.

Also, I don't think that the the wing is set up to generate faster-moving air on top compared to that underneath. The wing is tilted forwards, which means the air hits it, and get's shoved UPWARDS, which creates the effect of pushing the wing into the ground. If anything, this effect would create turbulence in the air above the wing, slowing it down, which means the faster, less turbulent air underneath the wing would create en extra bit of downforce as well. In other words, the wing does not function on the principle of the Bernoulli Effect, but is simply based on Newton's Third Law.

...or not. I'm only a Freshman Aerospace Engineer - so I have yet to take all those hydrodynamics courses and stuff...

Quote from 510N3D :Yeah but i think that due to the shape of the spoiler the air that is going upwards is actually repsonsible for the downforce.

Correct. It's a Newton's Third Law type of setup. Air pushed up by the wing pushes the wing and car into the ground.

That's what I meant - low pressure.

Would it have anything to do with negative pressure? I'm completely pulling this out of my @$$ but here's my wild guess:

Normally, as your car cuts through the air, a zone of negative pressure forms behind your car as the air tries to close that space behind you. This causes vortices and stuff, but also the simple fact that there IS a zone of negative pressure tends to hold your car back just a tiny bit. If another car comes in behind you, that negative pressure still exists, but now it is acting on two vehicles, meaning that it doesn't have quite as much of an effect on you alone.

The way I imagine it is if you take a box, with a pointed nose and drag it through the water, the square back end will cause enormous drag. Now if you stretch the box to make it longer (e.g. two cars in this capsule of negative pressure), and pull it twice as hard (two cars in this capsule giving you twice the power) it will still be held back with the same force as the water washes around the back end, but now you can go a decent clip faster.

Does that make any sense?

I swear to GOD when I have the money, a 4-projector setup WILL BE the FIRST thing on my list of cool projects to waste a couple grand on.

I'm curious. I know you can hack games and create your own files and mods and stuff. How come nobody has been able to do so in LFS? I by no means WANT that to happen, but I am wondering how it is that it hasn't been done. Is it really that difficult? I would assume with enough time you could reverse-engineer that 'proprietary setup.' Is it really just TOO complicated? Or is it just that no one has actually taken the time to do it?

That's good too - though you still need to apply Rain-X on the side windows if you want it to work on there too (which I do.) Still, though - I'm fairly certain that if you apply it by hand, it works a bit better.

With regards to the whole, "Well GT5 has 2 bajillion cars and tracks" argument:

Quality, not quantity.

That's it. I said it. The fact is that it doesn't matter HOW many cars or tracks GT5 has - it cannot hold a candle to LFS when it comes to the enjoyment of actually playing the game. You simply do not have an argument here. Everything you've said so far can and HAS been easily refuted with better logic.

How DARE you make references to such websites without providing the proper proof to back it up!

All I can say is, I don't really agree with people getting flamed for it as bad as they do sometimes...

...but sometimes it's a lot of fun to flame them hell out of them. 'Specially when you're in a really bad mood.

Quote from the_angry_angel :It's supposedly awesome on motorways, which tends to be where I do a fair bit of my driving

I can attest that Rain-X IS awesome on motorways. You'd be surprised how well it works. I guess it depends partly on the airflow over particular vehicle's windscreen, but I find that I hardly have to use my wipers at all after using the stuff. Well worth the trouble of putting it on.

Quote from Technique :One thing that may be annoying is that with a 3 monitor setup you have to use the left and right monitors in order to see the apex of the turn. You have to turn your head a good amount in real life too so in that respect it's more realistic. But in real life you don't have large plastic monitor bezels blocking your vision!

Try driving with TWO monitors. You're constantly staring right AT the 1" thick black bar! Although after a while you completely learn to ignore it. Still odd cause it makes anything in front of you seem a lot wider - be it the car or the road.

Yeah - accidentally left a few AI on the grid when I went to the strip yesterday to try something - and when they all blew by me and stopped, that's the first thought I had.

Quote from Dennis93 :i can see what you mean, but.. i'd rather see new cars , than new wheels

I'm sure it wouldn't take a week of development to implement this suggestion. In fact, I'd be willing to bet that the updated interiors that will supposedly be included in the next patch will have this feature.

Or not.

Quote from wtf im nameless :so I can pretty much drag and drop monitors where ever I want to, and the mouse moving from screen to screen will be perfect.

Yup. You can even account for the black bar(s) in the middle - though for anything other than games and MAYBE movies, that is just stupid.
