(classical music supposedly improves your intellect...) *Turnes on Handel's 5th* X-D *Go litle Gray cells, It's your birthday, It's your birthday* (Sometimes I even frighten myself...this is one of those times)

I believe the motion occurs because the energy used to stretch a spring is the same amount that is created when the spring is...un-stretched (for lack of a better word).

Lectvay »» models »» homepage Re: Intriguing Items of Discovery   posted: 08-Jul-02 23:13   »»  To be honest, I don't really understand why it behaves that way. I would have guessed that the zip-springs would pull the same amount and even out, as we have seen in other shapes. When your magic square is stretched to become a long skinny rectangle, you would think that the long sides would be stretched so far that they would have lots of force pulling it back. Why doesn't it? I don't think I completely understood your explaination, qwertilliopasd, and maybe that's why I'm still confused.

qwertilliopasd »» models »» homepage Re: Intriguing Items of Discovery   posted: 08-Jul-02 23:35   »»  I think I know... When a spring is stretched, It takes energy to stretch them. The springs on the sides are zip-springs; their length is zero so any length is being stetched. When a spring is let back to it's resting size, the same amount of energy is used to get to the resting size. Since this energy is equal, any energy "helping" one spring return to resting length offsets the balance, and that spring will return to its resting length. Sorry if that was too much physics-gibberish.

Try playing with them > to get VERY interesting results. (I haven't tried that yet, but) Theoretically: Friction would only determine the amount of momoentum (besides the "vibrations") Theoretically: Any change in K would just increase the force of the springs, but still the balance would remain (the size might change...)

The equillibrium (sp?) causes anything that happens to the zip-spring's length tho stay that way. Maybe it's because the zip-springs have no length. (the very notion of zip-springs is a "hole in the programming". Think about it: two masses are bound together with something that doesn't exist) I'm still "confuzzled" on that aspect. As I said: I just stumbled on this anomaly.
