Now here you look at a cylinder, right? let me draw the signal.
00:03
It's a vertical kind of cylinder, and this unit has cross -section.
00:08
So the cylinder, let me try to draw it.
00:11
So this has a cross -section, right? and it's fitted with a tight, feteen friction as piston, mass.
00:19
So this piston, let's say something here, right? so this is a piston we're talking about.
00:24
Let me try it with different colors.
00:27
So this is a piston, and this, and space is kind of going at this way.
00:36
So this is a piston, the piston here.
00:39
This piston has a mass which 3 .1 kilogram, okay? that's the mass of the piston...
