If an aileron is moved downward then the stall angle of attack increases or decreases and why?
Deflecting control surfaces, such as ailerons, downward will increase the maximum lift coefficient, but that maximum lift coefficient will occur at a lower angle of attack. The following plot is really about the effect of leading edge slats, but if you ingore the bit due to the slats, you can compare the two curves with and without flaps deflected 50°. A flap is like a big aileron. You can see that the maximum lift angle of attack is lower with the flaps deflected, but the maximum lift coefficient is much larger.High Lift Systems: Introduction
Can death row inmates stall their execution by eating their last meal really slow?
I actually read an account of the final death sentence carried out in France not too long ago, by one of the witnesses to it. The French sent torture-murderer Hamida Djandoubi to the guillotine on 10 September 1977. Before anyone else was executed, the Socialist government of Francois Mitterand took over and abolished capital punishment.On the morning of his execution, Djandoubi was allowed to have rum and cigarettes before he was sent to the guillotine. He attempted to prolong his life just a little longer by drinking the rum very slowly, and by asking for another cigarette. The executioner finally got tired of the act and insisted that the execution proceed. Once the scheduled time has arrived, things are pretty much at the discretion of the person in charge of the execution. If someone tries to drag things out like you’re describing, they can be forcibly taken to the place of execution.Here is the account, if you’d like to read it: 20 Minutes to Death: Record of the Last Execution in France
Help pop up problem!!!?
For the pop up, you can block it manually under the steps. Step1 Press the Esc key one time. If this does not help, press Ctrl, Alt, and Delete keys all at the same time. If a programs screen appears, select end task and left click your mouse one time. If another screen appears select end task and left click your mouse one more time. Hopefully your mission is accomplished with this five second procedure. Step2 If step one worked for you, you'll probably have to do it again each time you connect to the Internet, but only once per visit, until you go into your computer and delete this file that keeps popping up from your computer. Step3 If the above procedure is working for you, great. However, they may return again as invisible pop ups. When you're computer appears to be stalling for longer than normal, try the above procedure again, to see if the same program screen reappears. (Invisible pop ups are done away with in the same manner). Step4 If the procedure mentioned above did not help, disconnect from the Internet. Press Start, then control panel, then Internet preferences. Delete cookies and search history. Step5 If the above attempts were not enough, delete the user name and use another one. Step6 If the above attempts were not enough yet, you should ran an anti-spyware software ,then clean your registry make it faster. Recommend: Scan your Spyware/Adaware Scan your computer for viruses and spyware. Make sure and get rid of any nasty viruses or spyware that are located in your computer. http://toptenantispyware.com [if you do not have one]
Can a faulty kill switch cause a motorcycle to stall at high speed or under acceleration?
Yes.I had one bike (Yamaha XS 850) which did a very nasty thing: the engine stalled everytime I took a corner a bit too lively. Imagine being in the middle of a corner taken “con brio”, and as you open the throttle and expect that the oncoming acceleration will straighten up the bike, nothing happens, or better, the engine starts to brake more than before and the bike stays leaning all the way out of the corner. It can be downright scary.What had happened? It took me a looong time to find out because normally, you look at more fundamental things such as faulty ignition components, loose wire connections etc. The culprit was a spring, hidden inside the kill switch on the right handlebar, which pressed a steel ball into a notch and kept it securely in the central position.That bike in fact, as many Yamahas of the time (early 1980s) had a kill switch that moved left and right, rather than the more common up and down. It had three positions: Center = ignition on. Left or Right = ignition killed. The spring was rusty and it didn’t press against the ball strong enough, so the switch rotated under the centrifugal force in a corner taken a bit lively.Another bike that I had (Moto Guzzi T5), had a sidestand which also had a weak spring, so everytime I took a bump the sidestand opened out a bit and the safety kill switch, which was rightly supposed to prevent you from starting the bike with the sidestand open, would kill the ignition momentarily stopping the engine. Stronger spring fitted, problem solved.A third bike, a BMW K75, had the most complex system of interlocked kill switches, which were supposed to control the fuel pump. The fuel pump lived inside the tank, fully immersed in fuel, and was supposed to keep the fuel pressure constant at the injectors. Problem is that it was supposed to stop everytime the engine stopped, and also if the voltage was low, or the current at the pump was excessive, but it was programmed to keep the pump running for a few seconds to raise the pressure as you turned on the ignition, even if you weren’t pressing the starter button.All was well as long as the bike was new, but as it became old faults begun to appear and they were a nightmare to sort out, because of so many interlocking conditions.
How do I prevent plateau in muscle growth?
There’s three categories people tend to use to describe development in strength training, and your approach will be different in each:A novice is a lifter that can fully recover from an exercise in 2 days. Such a lifter can increase the weight every time at the gym, without any variation in their workouts. There’s no plateau if they eat and sleep enough. Most people will be a novice for 2–6 months.Good programs are StrongLifts 5x5 or Starting Strength.An intermediate is a lifter that takes up to a week to fully recover from an exercise. They will plateau if they try to go heavy every workout. They need to vary their programming day-to-day to allow recovery, but still get enough volume to stimulate growth. Typical programs are heavy-light-medium (3 days a week), or upper/lower body split (4 days a week, 2 upper and 2 lower). Most people will be intermediate for up to 2 years.A good program is the Texas Method.An advanced lifter is one who takes more than a week to fully recover. Breaking out of plateaus is a constant battle. They will vary their program over the course of a month or more. At this point, you probably will be using a customized program for specific athletic goals.Eating enough is very important to avoid stalling. You need to eat enough to gain weight—which for some people, can be a difficult task itself. Sleeping is also important, as this is when your body actually produces the new muscles. If you’re eating and sleeping right and find yourself stalling, that suggests you need to adjust your program to the next level up.See also Weightlifting Performance Standards for a sense of what numbers to expect at each level (though I wonder if their Intermediate numbers are a bit low). Note that these are for average athletic ability, so individuals can be higher or lower.
[SPOILERS] In Avengers: Infinity War, if the only way to win was to give Thanos the Time Stone, why didn’t Dr. Strange do it immediately?
There are multiple theories regarding this, I will try to enumerate what I think is most plausible.Image source : GoogleFirst Kayfabe reasons.Nebula factor - If you recall Nebula entered the battle of titan midway. She is going to be critical for what happens next. It is a possibility she would sacrifice her “parts” to send Tony Stark home. It was essential for her to be the part of the battle and bond with Stark to do so. Hence, he fought long enough for her to participate.Reality Check to Stark - Strange wanted to provide reality check to Stark. He wanted to show how hilariously outmatched they are against Thanos. He also wanted to give him a peek of what each stone can do, so that next time Stark will be prepared well. Alternatively he wanted Stark to draw blood to make him believe that Thanos can be defeated.Time stone availability - A weird but intriguing theory going around is that Strange was using time stone at that time in some future period. (to be revealed in next movie) In that case, he hadn’t that stone available at that time. Which means he couldn’t hand it over as he doesn’t had it in person at that time.Real reasonsThe Grandeur - For me Battle of Titan was the pinnacle of the movie, the highest high. I don’t think movie would have done that well if we didn’t have that scene. It is important to have that scene to make people delighted. My point is you can’t make a $2 Billion movie if every conflict is resolved by talking.
