Simple: you don't define it. That's was discussion and compromise is for. You can't reduce everything to a single scientific factoid that will be true always and forever. Too much regulation is as bad as too little.
The airline industry is a perfect example: heavily regulated for years, it started to stagnate and companies to struggle...then they eased a lot of the regulations...business boomed for a while...and then they eased some more...and some more...and now, due to too little regulation, from the point of view of the traveller/customer is pretty much back where they were during the too much regulation. There's only a handful of carriers left, very very little competition, and airlines are seen as some of hte worst companies in the country (topped only by Electronic Arts and cables companies).
last time someone tried this the cable company (comcast i believe? or time warner?) )got it shutdown.
now in that case, it was a small town deciding to do it for themselves and set up a new provider, rather than an existing provider like in this case. but if the local cable monopoly can stop that, they can probably stop this.
i figure the only reason they couldnt stop google was because...it's google and its harder for the local 800lb gorilla to stop a fellow 800lb gorilla than it is to stop a 5oz mouse.
This this, a million times this. most of the people talking about the sequester, and saying its no big deal, a lie, or didnt have to come from these sources, simply have no Fing clue what they are talking about. My favorite is the claim that the cuts are bogus because the budget is actually larger.
They have NOT READ the bill, and they do NOT KNOW how the government budget works, and they are no better than the politicians who are viewed the sequester as a win/win proposition no matter what. They knew they can blame the other side for it, and their supporters will gladly ignore their chosen parties complicity, and the posts here on/. only prove that.
Since I already have 6 of those games, and don't want the other 2, I wouldn't pay 1k$ for this card. By my math (~55$ per game), that's 440$ of games I don't need. $352 if assume a 25% markup. Thus, I would buy an OEM bundle of the card, for between $550 - $650. Makes sense to me.
(Ya, I know they get paid to include the games in the bundle...that's not my point)
i saw the part where they add what basically seems like an autorotation transition to the mix. i didnt talk about that, simply the general idea and engineering problems of slowing/stopping a rotor in flight.
Autorotation itself is interesting because it's another transition of forces. Whereas autogyros use autorotation by default, at all times, a helo does not. a helo effectively (but not precisely, because airfoil lift is more complex than simple "fan pushes air") directs air downward, or stated another way, air tends to flow down through the rotor. and in autorotation, the opposite occurs: the rotor is forces to continue rotating (providng some measure of lift) by air being forces up through it as the helo descends.
So another transition phase to consider, going from one set of dominant forces, to another. And helo pilots that I've met generally dislike autorotation training, so it could be interesting to ge the, onbaord with making it an intentional part of normal flight. Heh.
Right, and the S-69 before them, though it also never got to the point where they reduced rotor speed. Something about too much airframe stress. Slowing down the rotor would allow a higher forward speed with the same total force on the rotor, but the combined forces on the airframe as a whole, particularly in the support structure (rotor/body interface), could be an issue.
repairable doesnt mean 100% recovery. ever had a scar that never fully healed, leaving a small pock mark? It's repaired...but not 100% as some of the tissue is still missing compared to before. same concept.
this is actually one of the arguments for why we shouldnt wait for sometime in the future to make colony ships for interstellar exploration, but should instead start now.
No they didn't. What, you think it was a secret, or the knowledge just mysteriously vanished from peoples minds? The fall of Rome wasn't over night, it was over decades. And the people didn't just vanish, nor did the knowledge. The "Dark Ages" following the "fall" of Rome, wasnt really dark. Really the only thing lacking was this huge overarching unification and relative stability granted by being part of the roman empire, and even that was only in europe.
Farmers have been making crude cement for thousands of years. You think they never noticed that when sandy/gravelly soil and clay soil mix (effort to loosen up the clay soil so it drains/grows better), it only gets worse, such that you can't farm? Then somoene got thebright idea...whoa...this stuff is hard...we can't grow with it...but we can cut it into blocks and make walls and homes from it!
physicists do this a lot. I remember many years ago a physicist delving into philosophy, and getting nearly an entire Discover mag article devoted to him. Essentially took the abstract means of talking about physical phenomna, took out the equations, and then applied it to philosphy and logic and stuff.
hate when physicists begin delving outside their field. XKCD had it right.
Been done. S-72 and X-50 prototypes. Its very unstable. The bring a rotor to a controlled stop thing is easy, existing rotor brakes can be geared to align it fairly precisely when it comes to a stop. The lift transition is the issue. It's not just that lift is basically 0. It's that one half of the rotor disc (the theoretical abstract describing the lift forces) has to completely reverse the airflow of the lifting surface.
Its essentially an expanded case of the Retreating Blade Stall problem.
But the retreating half of the rotor disc has to, as some point, go from generating lift from a retreating motion through the air (moving backwards relative to airframe, due to rotation) to generating lift from an advancing motion through the air (moving forwards, relative to airframem though no longer rotating). The easiest way to think about it isnt to think of it as going from rotating to fixed, but rather think about a rotor that is simply being reversed in direction (simplfies a lot of math).
So at some point in the middle there, half the rotor disc will fall below stall speed, and experience a stall similar to the effect of a Retreating Blade Stall. Worse, won't regain sufficient lift until its now going ~100 KIAS in the opposite direction. Think of it as stalling between -100 and +100 KIAS (example number) as it crosses the transition.
The only craft I can see being able to cross that boundary zone would be a very small, very lightweight rotor that is able to make extremely fast accelerations, and thus cross the zone before it's able to affect the craft much. A full scale craft would simply have too much inertia/momentum to be able to make the transition fast enough, without tearing itself to pieces. Likewise for any craft trying to stop the rotor and use forward motion to generate the lift.
http://en.wikipedia.org/wiki/Sikorsky_S-72 The sikorsky S-72 demo prototype. Never actually made the conversion from rotary to fixed flight mid-air, but did fly in both configs seperately.
even if they dont eat that trash theyre still gonna be fat. It may be better than sitting in a chair for hours, but this thing hardly counts as exercise.
I'd say it sounds like you need to find better people to play with, at a place where they enforce the rules, and even kick people who arent playing for the objective, and just trying to be aholes. And don't rent equipment and buy supplies (reloads) at the paintball range. Hhave to assume you're doing one or both cause walmart and the interwebs have that stuff cheeeeap.
how exactly is this the WOT backfiring? We have no beef with the Chechens, and they largely have no beef with us either.
We dont even yet know what the motivations of these two whackadoos are yet, so it's rather early to be playing that card and start your preaching to the/. chior.
But honestly, the only reason I hope the 2nd one gets captured alive is so he can spill his guts (to confirm or deny any involvement or backers beyond themselves). his motivations I really dont care about; he specifically set out to kill/maim innocents, and there is zero justification for that, period. i'd hope he gets the death penalty, but Mass. doesn't have it anymore (since early 80s i believe).
