Okay, folks, so we're going to talk about problem 33 here.
00:05
We're going to be looking for the mass of the wire, and as you recall, i just want to remind you that when you have an infinitesimal line segment with a certain density delta, then delta multiplied by ds gives you dm.
00:21
That's the density.
00:22
I mean, that's the definition of a density.
00:24
Density is, you know, mass per length.
00:27
So when you do an integral of this, you're going to get the mass.
00:31
Of the entire wire.
00:33
Okay, that's really the idea, so let's calculate our problem here...
