So, here in this question we are considering about the movement of inertia of a rectangular lamina about an axis which is perpendicular to the plane and passing through the center of the mass.
00:10
So, here we can say that let's say here is a plane lamina we have to find out the movement of inertia of this rectangular lamina about an axis which is perpendicular to the plane.
00:21
Let's say this is a plane and we have to find out a movement of inertia about the plane which is perpendicular to the axis.
00:32
So, this is the plane which is perpendicular to the plane axis which is perpendicular to the plane.
00:38
So, we need to find out the movement of inertia about this axis let say this is a point.
00:43
So, from here let us say, if we consider about y axis let say this is the z axis from here let say this is the length l from here.
00:55
So, movement of inertia about an axis which is perpendicular to the plane is iy and this from here is ix.
01:02
So, both the planes are perpendicular from here let say this distance is b...
