00:00:00.240 --> 00:00:02.819 A:middle L:90%
indescribable were given point. Mrs. And Nowhere has
2
00:00:02.819 --> 00:00:05.769 A:middle L:90%
to find the moment about the origin. And where's
3
00:00:05.769 --> 00:00:08.730 A:middle L:90%
to find central myself? This object We know that
4
00:00:08.740 --> 00:00:12.089 A:middle L:90%
first of all, movement as summation off Bess is
5
00:00:12.089 --> 00:00:15.750 A:middle L:90%
multiplied by the distance to origin. So usually that
6
00:00:15.750 --> 00:00:20.089 A:middle L:90%
would be this distance, this distance and distance.
7
00:00:21.190 --> 00:00:23.239 A:middle L:90%
And since this one is on the negative side,
8
00:00:23.239 --> 00:00:25.839 A:middle L:90%
it will effect the origin or its will try to
9
00:00:25.839 --> 00:00:29.480 A:middle L:90%
move the central bus or the moment towards this negative
10
00:00:29.480 --> 00:00:33.100 A:middle L:90%
site. What I'm saying is that when we're summing
11
00:00:33.100 --> 00:00:35.560 A:middle L:90%
it up, we'll take that one. Has negatives
12
00:00:35.560 --> 00:00:39.240 A:middle L:90%
or 12 times negative three plus and these air on
13
00:00:39.240 --> 00:00:41.219 A:middle L:90%
the positive side. So the effect of those will
14
00:00:41.219 --> 00:00:48.390 A:middle L:90%
be positive plus 15 times two plus 20 times eight
15
00:00:48.880 --> 00:00:51.649 A:middle L:90%
. That is you go to the negative 36 plus
16
00:00:51.780 --> 00:00:59.030 A:middle L:90%
30 plus 167 moment about George Inness 1 50 For
17
00:00:59.359 --> 00:01:02.490 A:middle L:90%
now, he ordered Central I'd often object or central
18
00:01:02.500 --> 00:01:06.560 A:middle L:90%
mess is you going to x I am I Or
19
00:01:06.560 --> 00:01:07.670 A:middle L:90%
am I excited? Is the moment about the origin
20
00:01:07.670 --> 00:01:11.700 A:middle L:90%
divided by the total less? Be already find a
21
00:01:11.700 --> 00:01:14.000 A:middle L:90%
moment about the origin in first part. So that
22
00:01:14.000 --> 00:01:17.090 A:middle L:90%
is 1 54 We're going to divide this by information
23
00:01:17.090 --> 00:01:21.650 A:middle L:90%
off total SS or 12 plus 15 plus 20.
24
00:01:22.140 --> 00:01:26.409 A:middle L:90%
That is 1 54 divided 4 to 7, and
25
00:01:26.409 --> 00:01:33.030 A:middle L:90%
that is about 3.28 So the central mass is about
26
00:01:33.129 --> 00:01:34.879 A:middle L:90%
one exit three point to it so easily, that
27
00:01:34.879 --> 00:01:41.909 A:middle L:90%
would be somewhere around here. And if you were
28
00:01:41.909 --> 00:01:44.739 A:middle L:90%
to hold this system from here, and die system
29
00:01:44.739 --> 00:01:46.060 A:middle L:90%
would be in belts.
