the way it is drawn in the Mohr's circle, you have to make clockwise rotation of 2*phi from e1 plane to reach the principal axis. So, in the actual coordinate system, the principal axis is oriented at phi angle (anti-clockwise) from e1 plane. Of course, if the numerical value of phi after calculation turns out to be negative, the principal plane's orientation in the actual coordinate system will reverse.

very nicely carried sir. Thanks a lot
nice lecture sir.
What is angle (2*phi). I guess it is the orientation of principal axis w.r.t. e1 plane. can you please elaborate on this being positive and negative.

@@ajeet3856 Yes Sir. It was explained in the lecture next to this. I appreciate your response. Thank you.
