A Video for deriving expressions for min and max Inertia.

The video illustrates how to derive an expression for the minimum and maximum moment of inertia and how we can determine the direction of the major and minor axes.

The Timestamps for the video are shown.

0:00 – Introduction.
1:57 – How do we derive the expression of Ix’ and Iy’ for inclined axes?
5:57 –The Expression of tan2θ =2(Ixy)/(Iy-Ix).
