how many triangle are on the epcot ball ??

[mickeys papi]

my son asked me to ask the dis this question becauce the dis knows all how many triangle are on the epcot ball ??

From the Imagineering Field Guide to Epcot: "the outer sphere is made up of 11,324 individual triangular panels made of an aluminum alloy, each one custom fit"

It's not a ball, but I'll let that go.

According to this there are 954 but that seems kinda low to me.

Another source citing the same thing: http://architecture.about.com/od/geodesicdomes/a/spaceship.htm

I'd say the Imagineering guide is closer to right, it seems like it would need more than 954 to me.

Geometrically, Spaceship Earth is a derivative of a pentakis dodecahedron. It is a Class 2 Frequency 16 Icosahedron, with each of the 60 isosceles triangle faces divided into 16 smaller equilateral triangles (with a bit of fudging to make it rounder). Each of those 960 flat panels is sub-divided into four triangles, each of which is divided into three isosceles triangles to form each point. In theory, there are 11,520 total isosceles triangles forming 3840 points. In reality, some of those triangles are partially or fully nonexistent due to supports and doors; there are actually only 11,324 silvered facets, with 954 partial or full flat triangular panels.


So...11,324

INTERESTING FACTS

The geosphere is 165 feet in diameter and weighs 16 million pounds. It encompasses 2.2 million cubic feet of space and has an outside surface diameter of 150,000 square feet. It is covered by 11,324 triangular panels and held aloft by 6 support legs that are sunk over 100 feet into the ground.

It's too early and it's monday, that much math is just not neccessary. This looks like a question from my SAT's.

Are you sure, I was thinking more of a class 3? Well 2, 3 whatever it takes.

The panels are made of aulcobond. Which is a pannelling very similar to what we make signs out of at work! Very cool!

Is that anything like transparent aluminum?

 

[MinniesYooHoo]

Is that anything like transparent aluminum?

All right Scotty, can you build a tank with it?

 

[chartle]

no but you do know it a real material

http://en.wikipedia.org/wiki/Aluminium_oxynitride

Way to pricey and no need to look out of Space Ship Earth.

 

[chartle]

Yes see above.

Oh thought I would also get geeky with my last two posts.

Sure, but what happens to it if it is hit with a very large golf club? Will they break?
