Thanks for the explanation, this video helped me out a lot. Quick question, for finding sigma 3, shouldn't it be 0.38 ksi because it's sigma m (1.5 ksi) minus the radius (1.12 ksi)? Correct me if I'm wrong. Thank you again for the great walk-through!
You are correct! sigma_3 should be 0.38. I guess I can do mechanics but have some trouble subtracting numbers :) The max shear should also be adjusted to be 1.81.
Thank you for such a great video explanation! We know from this that the angle between x-axis to first principal stress axis, but what about the other two angles? for 2nd and 3rd principal stress axes?
In the first minute you gave me the answer I'd just spent an hour searching for. Thank you so much.
You are welcome!
Finally one of these videos actually makes sense
You're welcome :) Happy to hear it was helpful.
THANK YOU!!

It was on the tip of my tongue.

The principal-axis-1 is the z-axis. Principal-axis-2 is 31.7 degrees clockwise from the y-axis (in the plane normal to the z-axis).
