Physics Question?

Hi Everyone,   I know that this is not a project related question and I promise not to make it a habit, but my physics teacher stumped our class with a question today and I thought of all the smart people on Instructables one of you would know the answer. I have already search google to no avial. Is it possible to determine the volume of a flask given only the starting temperature/pressure and the final temperature/pressure? The number of moles are unknown. If it is possible how do you determine it? Thanks for your help!

Racing Game Physics

I've been designing a physics engine for a racing game for a long time now (months? years?) and I think that I've finally got almost everything figured out. The one thing that I don't know about is traction. So far my best guess for a formula is T = X + (Y * S)Where T is the stabilizing force on the car, S is the amount of slippage, and X and Y are two of the car's stats (probably measured in G's). This formula would be applied to each tire separately to account for the suspension.NOTE: The thing that might not be obvious here is that the car doesn't slip at all as long as X isn't exceeded.What do you think of this?

Physical Spectrum Analyser

Hi! I'm planning to build a physical Spectrum Analyser - a tangible model capable of showing audio levels (or something like that). A moving, undulating board of pillars that rise and fall with music. Spectrum Analysers split audio inputs into 'Bands' and normally then express these values with light boards (LED's). I want to use an audio input to create kinetic power. Is this possible? I'm thinking a series/grid of actuators might serve to raise/lower blocks and columns. This is all new to me! Much appreciated. Any thoughts?

A proposed projects for physics...

Hello there techies, the project USB charger was proposed by me to our professor in physics II. unfortunately he didn't accept such project HOWEVER he was happy. He just said that our project is not yet satisfying. He wants us to do a power inverter. We will buy a 2 6-volts battery and series it and it will output a 200+volts with a 30watts and then we will insert any charger such as a nokia cell phone charger and then voila, it should be charging. Do you think it is possible to do? And another project I proposed is that we will make a REAL TIME CLOCK using a 7 segment. I already had a schematic from youtube. and it uses a decade counter ICs but unfortunately I think such ICs are not available in our country, can you help us sir? T____T

LED physical durability

Heya, So, I'm thinking of making a flashing rattle, by using LEDs and batteries as the "stones" in the rattle. My thought is that when an LED randomly connects with a battery correctly, it will flash. But, will this destroy the LEDs very quickly? Shaking a light bulb is bad, but I think that LEDS are a bit more durable than that. Don't know HOW durable though. Any other thoughts that would help me?

Physics puzzle games- Auditorium, World of Goo and Crayon Physics

I really like puzzle games. I've played two that are really addictive and beautifully made, and found another that looks great.AuditoriumAuditorium has a free on line demo. I've played through the levels a few times. The full game hasn't been published yet.The screen has a stream of light particles flowing into it. You have one, or more, buttons that will affect the path of the particles: like one that bends the light stream to the right, or one that pulls it into a vortex. You move the buttons around to steer the stream into boxes that are scattered around the screen. There are many particles in the stream, and by careful placement of the buttons, you can split them into different paths. When you hit the boxes with light particles a new group of instruments join a symphony you hear. The goal is to get all of the instruments playing.Some levels have areas that will change the color of the light particles as they pass. Some of the music boxes are different colors, and you will have to route the light particles through the color changer before you send them it into the box. Try it out, the free online demo will make it very clear. I didn't even look at the directions. It's easy to find your way as you go. I love a game like that.PlayAuditorium.comWorld of GooIn World of Goo, you have to stick living gooey balls together to make lattice and build some kind of structure (tower, bridge, rope, ...) that allows the gooey balls to reach the end of a pipe that sucks them up. The Gooey structures are not stiff. If you don't build your structure carefully it will bend and can collapse under its own weight. It is a 2D game with a comic book style to the graphics. There is also a level designer and an online community where you can share new levels. I haven't experimented with these yet - I'm still working through the levels that came with the game.There is a downloadable demo for both PC and Mac. There is also a WII version for sale.It is drawn and designed beautifully. Totally addictive.2dboy.comCrayon PhysicsI haven't played this yet but it looks really great.The graphics look like they were drawn by a 5 year old with a box of crayons. When you get to a level, it presents a drawn scene with a star and a ball (it's actually an apple. Must be a tribute to Newton) somewhere in it. You have to draw some kind of mechanism, or ramp, or some objects, or... As you are drawing, the objects develop mass.Everything you draw then reacts with gravity. You have to harness the momentum you get from everything dropping to the ground in order to push, throw, drop or guide the ball so it hits the star.Look at the video it is self explanatory.

Computer program learns physics

From Wired:"In just over a day, a powerful computer program accomplished a feat that took physicists centuries to complete: extrapolating the laws of motion from a pendulum's swings.Developed by Cornell researchers, the program deduced the natural laws without a shred of knowledge about physics or geometry. ...Condensing rules from raw data has long been considered the province of human intuition, not machine intelligence. It could foreshadow an age in which scientists and programs work as equals to decipher datasets too complex for human analysis."LinkThe software has a long way to come, but apparently it's showing a lot of promise.What do you guys think? If computers can do physics better than humans, does that make human physicists obsolete?

Camera Stabilizer (Physics related)

I had an idea for a camera stabilizer a while ago which involves some basic rules of physics. I've done some thinking on it and I can't seem to figure out if it would really work or not. It involves two principles: 1.) Torque (t=f*d) 2.) Inertia (p=m*v) ---- The idea is to combine a gimbal design found on camera "gliders" like these: -Commercial product: http://www.bhphotovideo.com/c/product/521721-REG/Steadicam_MERLIN_Merlin_Camera_Stabilizing_System.html -Homemade design: http://www.diycamera.com/stabiliser/index.html ...with some sort of see-saw to counter the effects of up-and-down motion.  Ignoring the fact that this might be somewhat hard to hold such a thing, I just want to know if this would work. ---- Any balanced see-saw will have an equal amount of torque on either side of the pivot point. Therefore, a balanced see-saw will work with 500g hung 10cm from either side of the pivot point, OR 750g 5cm from one side and 250g 15cm from the other side (750*5=3750; 250*15=3750).  With this concept, I thought of designing this part of the stabilizer like a small camera jib (http://en.wikipedia.org/wiki/Jib_(camera)). That is, the camera on one end with a counterweight on the other. The pivot point would have a handle or some kind of vehicle mount on it.  The stabilization occurs (or so I'm thinking) because of inertia. Inertia=mass*velocity. So, when the pivot point (the handle) moves up or down, one of the sides of the see saw should move up faster than the other. The side that moves up slower (the longer side of the see saw, I'm thinking) should have the camera mounted to it.  ---- Is there a flaw somewhere in my thinking? THE QUESTION: Would both sides of an uneven length, balanced see-saw move up at the same time when the pivot point is moved up or down? I'm not really sure and I'd like to hear your input.

Physics question? Why doesn't this work? Answered

So included I have the original "troll physics magnet car" that supposedly would use magnets for propulsion. I know that it doesn't work since the front magnet pulls the car and the car pulls the front magnet, so the energy is evened out. But if you put a stronger magnet on the front, then the smaller magnet on the car wouldn't have enough strength to equalize the larger magnet, so why wouldn't the car move forward?  What if you applied the same idea to a generator? (look at the picture with the circles and rectangles) Wouldn't the bar magnets continue to repel each other and make the generator wheel would spin forever? If the wheel was balanced and was given a little push to get things going, I don't see what the problem would be. I'm not planning on building this machine, so trial and error is out of the question for me.  Please help!

Physics - Tech engineering software, that is fun?

Hi, Just a quick question... I ran across something called Gmod, or Garry's mod software today by accident. This one here... http://www.youtube.com/watch?v=Ui7S1ToK49Q&feature;=related It looks pretty neat, sort of a mechanical play thing. But, I'm not sure how true to reality the software is, also you apparently need to own a main platform software to use it, like Half Life. I don't have any of the games needed to play around with Gmod. I started to wonder if there is any other software out there that works as an, across the board experimenter's virtual lab? Sort of a mechanical, electronics virtual plaything? I'd think that engineering tech schools would have software such as this, (CAD comes to mind) but I didn't quite find what I was looking for with a google search... Not exactly sure what the best search term would be for something like this? I've come across virtual electronics software, but maybe I'm asking too much for a multi electro-mechanical environment. Has anyone ever used software like this, particularly something fun to play around with, without being to dry? Free would be nice as well, but I'm probably pushing the envelope there a bit! LOL.

See What's Really Happening in Physics -- arXiv.org

If you are curious about what "real physicists" do, or what the current "hot topics" in research are, take a scan through the "recent postings" at the Physics Preprint Archive. Started for the High Energy Physics community in 1991 at Los Alamos National Lab under the name xxx.lanl.gov, and with a purely e-mail interface(!), arXiv moved to Cornell Univerisity with its creator in 2001.The archive includes preprints from all areas of physics research, not just HEP, as well as computer science, mathematics, and quantitative biology. "Preprints" are a way for the research community to get their results out for everyone to read, during the often lengthy period (months, sometimes!) between submission to a journal and actual publication. In many fields, it has been traditional for decades that printed copies of "preprints" were mailed out, sometimes in regular batches, between major University departments. That mechanism has been superseded almost exclusively by the arXiv database.Besides these traditional pre-publication journal articles, the archive also often includes conference proceedings, and submission of much older published papers of general interest to the community. There's also (usually in the general "physics" category) a scattering of crackpot nontraditional science papers.

Few questions about coil physics and capacitors.

Hello.  Hopefully there's some smart electromechanical and physics guys on this board. Long story short I have been working on a coil gun project for about a month now. Originally I was using disposable flash camera circuit, a simple push button, and a coil I took out of a fan. The coil itself is roughly 42 gauge wire, wound an inch long with about 14-18 layers. I achieved best results from this coil, about 4% efficiency, using a 200v 470uf capacitor and a magnetic projectile. However when I used a more powerful capacitor rated at 400v 820uf efficiencies were much lower. I realized the coil was limited and the capacitors energy wasn't being maximized. So I bought some 16 gauge magnet wire to wind a new coil. I wound a coil 40mm long, 3 layers thick around a 1 cm pvc pipe. The coil works but once again there is a huge loss of efficiency at higher energies.  So I need to wind a new coil.  Now here are my questions. 1.  I have read that a coil should be about 33% longer than the projectile.  Is this accurate? 2a.  Is there a magical equation to determine the number of layers a coil should have if all other factors are known? 2b.  How many layers of 16 gauge wire should I use for a coil wrapped around a 1/4 inch barrel to maximize efficiency with a 400v 820uf capacitor?  What about a 200v 1200uf capacitor? 3.  Could someone please demonstrate how to convert farads into amps? My main objective is an optically triggered multi stage coil gun with kinetic energy transfer of above 30 joules. I've moved away from flash camera circuitry and am now using dc to dc converters to charge the capacitors.  I need to find out how to convert farads into amps to figure out what kind of transistors I need for the trigger switch.  Any help is truly appreciated.

Graphical User Interface Library for Physical Computing in Processing

Visit our blog:    http://blog.butterflui.org/?paged=3 The subject of physical computing, especially in the field of robotics, is a fascinating area that has already begun its triumphant in universities, schools and hobby applications and is developing with impressive speed. It is highly interesting that Pyhsical Computing and Robotics, more than any other area, can merge many different areas (engineering, design, psychology, biology and many other areas). Our target groups are mainly users with robotic and physical computing affinity: engineering, programmers, mechatronics engineers, product designers, interaction designers, communication designers, robotics, interface designers, developers, electronic engineers and artists. There are people who want to monitor and control the input and output of their system without major effort in which they rely on an interface library. Robot experiment sets are increasingly being used in short-term projects in schools and universities to provide basic knowledge on physical computing. Our analysis of current sets shows us that existing features don’t cover all aspects of robotics. The aspect that has been neglected so far according to our research, is the controlling and monitoring of experimental physical computing projects through a graphical interface.

Received Instructable.com request for my physical address to qualify to receive an animated holiday card. Is this Legit? Why know physical address for this? Anyone else get one of these notices?

I received a notice from Instructables.com with request that I identify my physical address to qualify to receive an automated greeting card...???  Is this legit? Why do they need to know my physical address? This really sounds odd to me.  Anyone else get one of these kinds of notices?  I really LOVE Instructables.com   Its awesome fun for those who like to do projects not just talk about them.

How to connect a physical pushbutton to a display to trigger an animation.

I'm trying to figure out how I would set up a physical pushbutton so as to trigger an animation once pushed.  The programming language I'm using is processing, and the content would be played on a 32" screen.  So I'm trying to figure out what type of hardware I would need (circuit boards, pushbuttons..etc) in order for this to work.  Thank you in advance to anyone that offers some advice.  P.S. I also have little knowledge in programming this is a project so I can become more familiar with it. Thanks!!

How can I make a physical randomized trigger?

There is a board game called "Pie Face" that uses a randomized trigger to release a hand that has whipped cream on it- which splats into your face.  So the trigger cant be so strong that it breaks your nose, but fast enough to hit ones face before their reflexes dodge it.  I would love to get my hands on one of these to figure out how the mechanism works, but the game is unreasonably expensive.  Anybody have any ideas?
