TEXT FROM YOUTUBE TRANSCRIPT
I’m going to introduce
00:04
you to how to construct the C6XTY ball
00:08
from the six component parts and you’ve
00:11
seen them by now they’ve arrived in the
00:13
mail or a box and we’re gonna at the end
00:16
of this introduction we’re actually
00:18
going to construct the cuboctahedron so
00:22
bear with me but I’m a c60 component is
00:25
actually comprised of two hexagons and
00:29
two Pentagon’s and together they come
00:37
together and you’ll notice that what hat
00:41
what’s happening here is that the that
00:45
there are 12 hexagons occupying this the
00:50
6c 60s so that leaves eight virtual
00:54
hexagons and they are used for this
00:57
locking mechanism so as these three
01:00
pieces come together then this forms the
01:04
sixth the virtual hexagon which holds
01:09
these six pieces together and with the
01:11
palm of your hand you can lock that
01:14
together as such now I use in this
01:20
assembly I use a this is vastly overkill
01:23
but I use a 10 millimeter allen wrench
01:25
and just give that a little cinch the
01:28
palm of my hand is not able to do that
01:31
so I recommend you go out and get a 10
01:33
millimeter wrench I think you’ll find it
01:35
everything goes a little bit easier and
01:40
there it is we’re just going to quickly
01:44
do that assembly so there eight of these
01:49
locking caps now that we’ve completed
01:54
the construction of the c60 let’s begin
01:58
to attach the tension members now
02:00
ultimately this is going to become the
02:03
cuboctahedron so this very first member
02:06
will in fact receive 12 tension
02:09
and then all the others will be arrayed
02:11
around that so let me demonstrate to you
02:14
how that gets constructed I want to show
02:17
you that remind you that we have these
02:20
hexagonal faces and we have pentagonal
02:23
faces the hexagonal faces are in imagine
02:30
them as connectors in a chain-link so we
02:34
will start here and link to their start
02:37
here and then they are so on and so
02:39
forth so they will then be part of a
02:42
line and so I can take any hexagon and
02:48
attach connector it doesn’t matter what
02:51
color I have some baby blue ones here as
02:56
well and then it’s important to remember
02:59
that the next connector then goes in the
03:05
same line so you’ve now attached all the
03:10
tension members and you end up with this
03:15
very awkward looking object but note
03:21
that the tension members are all aligned
03:28
but they are each orthogonal to the
03:34
other so that this has the appearance
03:37
being bounded by a box so those are the
03:41
Cartesian coordinates binding the
03:43
truncated icosahedron into a box now the
03:47
next step is simply to continue with
03:50
this effort but we want to do this with
03:53
the virtual locking ring or the
03:58
hexagonal face up and the reason we do
04:01
that is that that then puts all of the
04:05
tension members into tension so if it
04:08
were in this orientation everything is
04:12
just being stacked on one another much
04:14
like stone piling but if we’re in this
04:16
orientation then everything is going to
04:19
go into
04:20
you’ll see that as soon as the
04:22
cuboctahedron is we’re trying to
04:24
continue along this chain now do think
04:29
of it as a change so here we have link
04:32
and another link and another link and so
04:35
on and so forth only there are links in
04:38
the three planes of the Cartesian
04:41
coordinates so I’m simply going to then
04:43
continue with that so every time I
04:45
position one of the C 60s I need to do
04:49
it in such a manner that the hexagonal
04:52
faces are going to permit the
04:53
continuation now one of the results of
04:56
that is that the virtual locking ring
05:02
hexagonal face will appear north so we
05:07
can put this directly into this location
05:10
here and then grab another and we can
05:15
begin to go throughout the structure and
05:18
just simply following that paradigm
05:22
again we’ve got two hexagonal thick hey
05:26
we’re back and you can see now that
05:28
we’ve introduced the three at the top
05:31
and the three at the bottom very much
05:34
like the bowtie crystals so these are
05:38
essentially the same top and bottom and
05:46
we have some open tension members around
05:50
the middle of this the third layer of
05:53
this so let’s go ahead and begin to
05:55
assemble that layer again note that we
06:02
can see it everywhere so we’re here we
06:04
have a chain of tension members here we
06:09
have a chain of tension members so I’m
06:11
simply continuing that chain and then
06:16
there’s the hexagon ready to have the
06:21
next tension member associated with it
06:23
numbers which complete the stability
06:26
instructor
06:27
so we’re just going to add those and you
06:30
note that if all the orientations are
06:32
correct why you have to do is insert
06:34
these things in there automatically
06:36
aligned with its neighbor so here it is
06:43
I note that this is tension members
06:47
heading off in that direction if I just
06:49
simply look down here keep that
06:52
direction in mind and looked in here and
06:56
it’s already aligned for the next one so
06:58
I can just simply you’re looking at the
07:01
cube Oh octahedron
