00:01
All right, so if you draw this figure, you'll notice that from that point to all the way to the extreme, we have 200 millimeters, right? and we'll have 100 for that.
00:30
This is 100 millimeters.
00:34
This is 30, right? also, there's another 30 millimeters, right? and from this point to that point is 140.
00:50
I've deducted 60.
00:59
Okay.
01:01
And this is, of course, a1, a3.
01:04
Okay, i'm three, i'm two, and i'm one.
01:08
Okay, so this is two, this is three.
01:16
All right.
01:17
Let me write it well so that we don't have any confusion.
01:21
So this is a2, this is a3.
01:29
Okay.
01:30
So therefore, for us to figure out these ascent weights, remember, we're looking at x and y.
01:40
Okay.
01:49
So therefore, if we have that, i'm going to have to label that x prime and y prime.
01:57
So looking at that ascent weight, that some sort of a coordinate for that, right? so, ascent weight for, we're going to have x and y.
02:11
So that, so which means that for x direction, we're going to have 1x1 plus a2x2 plus a3x3 over a1 plus a2 plus a3, which basically translates to a is the area of the region in that particular arm.
02:41
And the centroid of the a1 from the origin, remember, in x direction...
