In this example, we're asked to find the center of this following object.
00:06
Okay, so we're going to be looking at only this shaded region is our object here.
00:12
Okay, we go all the way down.
00:13
We want the center of mass in the x direction and of the y direction.
00:19
Okay, so this point right here.
00:22
Okay, let's say this starts at the origin.
00:25
Let's call the origin right here.
00:27
So this is going to be 0, 0.
00:30
This object is made up of some uniform material.
00:33
Okay, so we don't need to worry about the changing in density.
00:36
Okay, we see that this object does have symmetry about this center here.
00:42
Okay, so all we need to do is find the center points in the x and y direction and we're all set.
00:48
So let's see here we go from 0 in the x direction to let's see.
00:55
Actually, i'm going to move the origin over.
00:57
I just realized they don't tell us how far we are from this point here.
01:01
So let's call the origin instead.
01:03
I'll call the origin this point...
