three words... "Magnetic Linear

Accelleration" That thing might go do fact it would break the track, but probably

not.

"LIM's" Linear Induction Motor, intamin uses those, but I think

those would be a little big, lol. I would think that it would just brake the magnet you

have on the car because if you turn the magnets on, there would'nt be anything

to pull on until the car comes along and even then, the magnet would not be big enouph

to brake the track, just the car magnets.

Ok, first of all, to set things strait, Superman: The

Escape, doesn't use Rare Earth Magnets or true LIMs. It uses a very special

electro-magnent called a LSM (Linear Syncronized Motor). I don't feel like

explaining the difference between a LIM and a LSM right now, so PM me if you

care. All you need to know is that a LSM is more powerful than a LIM.

I

am making my own LIM and believe I understand its physics. So I don't

completly understand/believe in the earth magnets, but I know my LIMs.

im talking about magnetic linear acceleration... why

dont i just call it MLA so i dont have to type it out. Yes of course MLA uses magnets

buts it is basically a domino effect of kenetic energy.

each frame in this video shows 1/30th of a second. the video has six frames,

so if you do the math the total video shows about 1/5th of a second.

keep

in mind the mechanism is a foot long. if you notice, only two frames pass before it hits

the tape meaning the last four frames are the tape moving after the mechanism was

fired. Do the math again and that is 1/15th of a second to pass through the foot long

mechanism.

If someone could use this idea of a gauss rifle, which is

principled on MLA that that fould for sure be a great launch

[gforce]

I don't see how exactly that would work, The

image isn't that clear.^^^

[live4bb21]

ok try this link, it shows the project that you make...

this is also how i found rare-earth-magnets.com

http://www.scitoys.c...nets/gauss.html

BTW this is my science fair project for this year, thats why i know a lil bit

about it

[gforce]

I wonder if you made weak magnets to start and then

strong ones as you go and the last one repel If it would work, I don't really think

so.

EDIT: How could you attach the Gauss Rifle and the coaster car to

connect?

It uses rare earth magnets in

combonation with LIMS for the initial launch and LSM for pickup and breaking. It

uses all three.

i

threw out the idea, its someone elses job to do that lol... i dont know exactly how yet

but i'll keep thinking

[gforce]

you could hang them above the track on a string or on

a C shaped box on the side. If you hang them just try to use the least friction possible.

Where did you hear that? Ive my whole life have been told in books, online,

TV everywhere that its just LSM's and that LIMs or Rare Earth Magnents

weren't used because they werent powerful enough to do the job.

SFmm freak is right, I don't know about superman using LIm's but it

does use lsms's, oh by the way hope you don't blame me for mixing

lim's with lsm's in my earlier post, lol. Huge rare earth magnets are on the

bottom of the cars, and the electric magnets are on the track, and how would the car

move if there were'nt any magnets on the car ?, I even saw on a show titled

scream parks and have it on video showing jim black demonstrating the power of the

magnets on the bottom of the car, putting a wrench to it and it pulling it to it's

surface with an extreme amount of force.

I have that same show on

video. You can see Riddler's Revenge under construction in the background in

that segment.

Saw that!, lol.

[joshg678]

the easiest thing to do is get powerfull magnegs and

put them on the track like this: \/ and have a strate thing on the bottom of that

car and have the repelling side on the inside and the attracting side on the outter side,

its thats simple. LOL
