Sound and tension

i do not knwo how to handle this problem
i am trying to determine a certain tension in a string
let take a example that evryone can understand
suppose i have a bicycle wheel and i want to have all spoke's (strings) the same tesnsion but also determine or that they have the right tension
Let say they must have all 120 kg /f so about 1200 N each
How do i determine this?
any ideas?
i see all kind of problems like damping of hub and rims and that kind of things and how do you get the same frequentie on all strings?

How exactly are you trying to bring LabVIEW into all this? Are you trying to measure the tension from the fundamental frequency?
Here is a formula: http://www.bikexprt.com/bicycle/pitcheqn.htm

  • Help!! Static sound and Lock ups

    I recently updated to the newest Ipod Mini version software 1.4. and when i play the songs on my ipod i get static sounding sounds and when i look at the display timer, it looks like the ipod i slowing down.
    Also i'm getting lockups when i'm browsing.
    Ipod service told me to restore the ipod, and i have 3 times, 1 to the factory software version, and twice to the newer version. It didn't help, as i'm still hearing static sounds, and I've switched headphones and headphone jacks, and it still doesn't help.

    the exact same thing happened to me. Mine is an original mini which needless to say is out of warranty, so I need an answer that is not "replace the hardware". Is there a way to restore it to a previous version of the software?

  • Disable sound and/or vibration while in Messages app?!

    Hi!
    I would like to know is there some option in the iOS where I could disable sounds and vibration while I'm using Messages app (app is open and the display is turned ON and I can see the message I recieved). This is very annoying when I'm using iMessages and getting a message every few seconds and then my phone vibrates constantly. It is of course OK if I'm not in Messages app but when I'm already using it I don't need a notification I got a message when I can see it for myself.

    I'm having the exact same problem. I get a random text message ding for no discernible reason at least oncer per day. No alerts from apps, no email, no texts, no missed calls, no voicemails. It's not changing connection types between wifi, 3G, and edge. I know that the first gen iPhones sometimes dinged in that situation. If anyone knows what's causing this I would love to hear it.
    Just to be clear I'm using a perfectly normal, not jailbroken, iPhone 4 running the latest software version.
    Regards,

  • HP ENVY TouchSmart 4 Ultrabook - Sound and Video Lags and Distortions

    This issue has been previously reported and noted as solved, but it is not solved. See the link to the other post below.
    Ways in which I attempted to address this myself...
    I first re-installed all drivers and updates, including BIOS updates. After that didn't fix the problem, I did a full wipe/re-install of windows 8, and again, updated all drivers from the HP website. This issue happens on both Windows 8 and Windows 8.1. I then did an exchange, and even the new exchange ultrabook is experiencing this issue. HP technicians, there is something faulty with this device. Please acknowledge and address ASAP.

  • Satellite P200D-11R sound and graphics crash after waking up from sleep mode

    Hi,
    I am wondering if anyone here has had similar experiences to mine (below) or can offer any solutions.
    I have upgraded my P200D-11R OS to Vista 64 Ultimate to take advantage of the extra performance. I also add that the BIOS has already been updated to version 1.4.
    Well, everything works fine with the standard 2Gig of RAM which the laptop was supplied with originally, however, when I upgrade the RAM to 4Gig (2 x 2GB Samsung 667mHz modules), sound and graphics problems appear every time the machine is brought back from sleep mode.
    The sound card makes a very laud fuzzy noise every time it wants to play a sound and the graphics produce lots of horizontal lines on the screen. I then just have to restart the machine which means loosing all my unsaved work.
    Everything works fine as long as the machine does not enter sleep mode. I have currently disabled the sleep mode to prevent the machine from entering it but I am finding life very hard without it.
    I am very surprised and also disappointed at the fact that Toshiba did not test these machines with Vista 64 Ultimate and 4Gig of RAM!
    Extra info:
    The memory is the same Samsung type as the 1Gig modules supplied by Toshiba originally with the machine, and the part number Toshiba recommends.
    I have tried installing other (more recent) device drivers by Realtek and ATI without any improvements.
    The memory modules pass all tests and are not defective. They have also been tested on my friends Dell notebook with no problems even in sleep mode.
    I have installed my friends Dell 2Gig memory modules in my P200D and they too produce exactly the same results with post-sleep crashes.
    My thoughts are that this must be another BIOS issue unless anyone can shed some light on the issue from another angle.
    Please help! Many thanks in advance.

    Hi Sascha
    Since you are running a Vista 32bit version, the upper limit of the memory recocnised by the machine is 3.2gb which is the maximum a 32bit operating system can address and use. The diffrence here is that I also upgraded my OS to Vista Ultimate 64bit to get yet better performance out of the 64bit dual AMD processor.
    3.2gb of RAM on 32bit OS does not necessarily increase the performance. However, it keeps the performance stable when you open many more programs at the same time since the machine has more RAM to play with before staring to use the much slower hard drive as operating memory (Page File), to keep all thoes open programs running.
    A 64bit OS such as Vista Ultimate 64, recognises the whole 4gb of RAM and much more (for instance, 8gb with 2 x 4gb RAM modules). The 64bit OS itself would generally consume more RAM to start with, however, with 4gb I found the general performance to be much better. Going back to the problem however, my P200D-11R with Ultimate 64 and 4gb RAM refuses to wake up from sleep mode gracefully and the graphics and sound crash every time, forcing me to restart.
    My feelings at present is that eventhough your machine may be slightly different, I bet if you upgrade your OS to 64bit, the machine will start recognising all of the 4gb of RAM and post-sleep crashes will start to appear!

  • When playing games on the ipad I have no sound and it it very slow.

    when playing games downloaded from the app store I have no sound and the games arte very slow?

    Try this  - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
    Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
    If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

    iPad running slow? How to speed up a slow iPad
    http://appletoolbox.com/2012/07/ipad-running-slow-how-to-speed-up-a-slow-ipad/
    If You Think iOS 7 Feels Slow Here’s How to Speed It Up
    http://osxdaily.com/2013/09/23/ios-7-slow-speed-it-up/
    You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

  • HELP! Uploading AS3 Game to server, no sound and Spacebar doesn´t work HELP!

    Hello, relatively new to AS3 and flash, this is the first time i am publishing anything. We are trying to upload our simple flashgame to our webserver, the game works perfectly fine locally save for one thing. We get an error regarding TLF which says it wont stream or something. So when it gets online, no sounds play and spacebar doesn't work, left and right arrow does work. We have three TLF text fields that are used to update score, lives and show you final score. If i turn these into classical text they stop working.
    Things we have tried: Changing default linkage from RLS to Merged into code, changing the text boxes to classical text(they then stop working), made sure the paths are correct(all files are in the same directory including the .swz file)
    This is the code from the soundclass:
    package 
        import flash.net.URLRequest;
        import flash.media.Sound;
        import flash.media.SoundChannel;
        import flash.events.*;
        public class MySound
            private var bgSound:Sound;
            private var fireSound:Sound;
            private var waterSound:Sound;
            private var earthSound:Sound;
            private var lightSound:Sound;
            private var soundChannel:SoundChannel;
            public function MySound()
                soundChannel = new SoundChannel();
                bgSound = new Sound();
                var req:URLRequest = new URLRequest("BackgroundSound.mp3");
                bgSound.load(req);
                //fire
                fireSound = new Sound();
                var req2:URLRequest = new URLRequest("soundFire.mp3");
                fireSound.load(req2);
                // water
                waterSound = new Sound();
                var req3:URLRequest = new URLRequest("soundWater.mp3");
                waterSound.load(req3);
                // earth
                earthSound = new Sound();
                var req4:URLRequest = new URLRequest("soundEarth.mp3");
                earthSound.load(req4);
                // light
                lightSound = new Sound();
                var req5:URLRequest = new URLRequest("soundLight.mp3");
                lightSound.load(req5);
            public function playBgSound()
                soundChannel = bgSound.play(0, 999999);
            public function stopBgSound()
                soundChannel.stop();
            public function playFireSound()
                fireSound.play();
            public function playWaterSound()
                waterSound.play();
            public function playEarthSound()
                earthSound.play();
            public function playLightSound()
                lightSound.play();
    I can somewhat get that sound can bugg out, but why does spacebar stop functioning? ANy help is greatly appreciated as this has to be delivered in twelve hours(published online) for a school assignment.

    Also might add publishing it locally in my own browser everything works, as does ofcourse playing it in flash itself. Changing from RLS to merged into code stops the error from coming, but doesn´t fix the problem on the server.
    Code from main class related to sound and spacebar:

  • I am having trouble keeping the quality of my video when exporting to my external drive.  I change the kind to "original" but when I view the video from the external drive once exported, the sound and picture are distorted.

    I am having trouble keeping the quality of my video when exporting to my external hard drive.  I have tried to export from iphoto with changing kind to "original" but when I open the video from the external drive the quality is effected.  I have also tried copying the video to my desktop and then dragging and dropping onto the drive...same problem. Any suggestions?  I would like to save everything to my external drive so that I can delete all of iphoto library and then reimport to correct a few things.

    The file sizes are identical.  In the finder I did a search for all .mov files.  Then when they came up, I went through them and named each one so that they would be easier to find.  I am a new mac user and am used to windows.  I realized later that I should not have done this....with a mac files should be named within iphoto app...not finder....When I went to open the videos in iphoto, it wouldn't allow me.  I had to go into finder, copy to desktop and reimport into iphoto.  Then the videos worked again.  However, I had the problem with the poor video quality when copied to external drive before that.  Actually the first problem I had was when I copied to ext drive...videos were copying as an image...so I learned that you have to change "kind" to original before exporting....then that problem was solved...now they are videos, not images but not of a great quality.  Skips, sound and images are not in sync...etc...

  • Can you record sounds and save as a ringtone with the IPhone4?

    I'm new to the IPhone. All other phones I' ve used in the past I could save sounds and use them as a ringtone. I just can't seem to figure it out with the I4. Can it be done?

    You can record sounds with the Voice Memos app, then sync them to your computer by selecting "Include voice memos" on the Music tab of y0ur iTunes sync settings and syncing your phone.  Once synced to your computer they will appear in a Voice Memos playlist that iTunes creates on the left sidebar.  Then you have to convert it to a ringtone using iTunes as shown here: Create free ringtones with iTunes 10.  After this is done, you can check the ringtone in your iTunes library, then check Sync Tones on the Tones tab of your iTunes sync settings and sync.  Custom ringtones will appear in Settings>Sounds>Ringtone at the top of the list.
