Just multiplication, division, addition and subtraction! There are a number of variables but it's not too bad. Gravity could be added without too much work.
MIT stands for the Massachusetts Institute of Technology. It is one of the best Engineering schools in the world. MIT is the developer of Scratch too, as you can see in the web address: scratch.mit.edu.
excelent simulation! espesially the last one. Intresting because most people would actually think that the more cycles per minute the higher the peak will go which is incorect! its about frequncy, for every size the shap is it will have a preferd frequency in which its amplitude will be at its larges, vabrate a large shape to fast and its going to be all over the place and vibrate a small shape slowly it wont catch a rhythem!
This is awesome! I loved the one that you could plot the peak amplitude. This is pretty ironic because we were just studying waves in school (So I know what amplitude really is now, lol). How do you come up with all of your great ideas for projects?!
Thanks! Lately, the ideas have come from looking at other people's work and thinking about how to take the concepts futher or in a different direction. I'm glad you enjoyed this one...vibrations and waves are amazingly cool.
Are you an ME? Me too! My BS was Univ. of New Hampshire class of '80 with my MS from MIT in '85. I'm sorry to say, all that pricey knowledge has pretty much rotted away...
Thanks! Sometimes it's hard to know when to quit...I originally had this project doing the entire frequence sweep automatically, including the plotting. But then, it took half an hour to run it and what was the fun of waiting around for it? Plus, I had trouble determining when steady state had been reached so I decided to make it much more manual.
Very nice simulation. I gave it a love it even though there needs to be more levels to this game. A good remix of this would change the sprite appearance, etc. to simulate a slinky anchored to one side. You could also vary the normal vector of the final (rightmost) slinky sprite and rotate the others accordingly,
Very very cool! It is amazing... I dont see how its possible to be this good!!!! WOW! I mean, I see how you can get the dots to follow the pointer,,, anyway, wow. Another great Paddle2See Hit!!!
I see peeks at 29 (129) and 63 (62). (IcedTea Java Plugin on Ubuntu linux, AMD Sempron 2800+) There may be other smaller peaks, but I think testing it out of order may be causing other waves... Interesting. I think your theory is still holing up... But I'm not able to test on windows with the official Java.
There's a future for me in engineering! awesome! :)
I like that you can grab any point., I struggled with this idea. Yours works well. I was trying to have mass in my fire copter's bucket, to require more force by the helicopter when it's full of water- and not be a bungee cord- but I think I was changing the wrong variables. I need to study springs more. You may find these interesting too: http://www.gaffer.org/game-physics http://freespace.virgin.net/hugo.elias/models/m_main.htm

the pluck isn't fixed lolz click the end an you can drag it.

Well, so you can! By fixed, I mean it won't vibrate on it's own...I think I'll leave it the way it is. Thanks for pointing it out though.

what kind of math did u use? I sould take a look. This would be awsome if I could learn how to do this. Could you add a gravity funstion?

This is a fantastic project! You always flesh them out so well, with lots of cool details. I love the various setups and the graphing is a nice touch.

The normal vectors should be doable...not sure about the more levels...

But I found a gitch, when you try to move it when you are on the 'cycles per minute' thing you can move the ball.

You mean move it with the mouse? Yeah, I guess you can! But then it trys to snap back on to the shaker position...kind of fun!

Woah, this Project is good for making Game's with velocty and gravity (well not REALLY velocity) anyway, bye.

What do you mean 'not REALLY velocity'?

Well it's kinda hard to explain. :S but oher than velocity, I dont know what to call it. :S

Yeah, I found myself getting very different peaks on the same computer, just different time. Maybe something was bogging down the processor?
