Thanks for watching and glad to help. These concepts are difficult, and repeated exposure from a different point of view may help. Congratulations on your Masters. That's excellent.
This was one of the best lectures I have seen. You made learning this material so enjoyable and easy to pick up, amazing teaching style thank you for your comedy!!
This was very informative - thank you!. This is coming from a person working on intermediate axis momentum wheel stabilized telecommunication spacecraft.
Hi Dr. Ross, I have a question about the stability and rotational energy of principal axes. You said the highest principal axis (the axis where the highest moment of inertia happens) has a lower energy dissipation than the smallest principal axis. I'm trying to understand this from a mathematical point of view. For rotation about the smallest moment of Inertia, can you say the angular velocity (w) decreases over time, leading to a decrease is energy, E? E= 1/2 w^T * I* w. And can you also say energy can be dissipated easier simply because the system's energy is more focused on angular velocity than the moment of inertia (it is harder for a system to remove mass than energy from rotation)? Thanks. I hope you can understand my question. I am confused about how and why the highest principal axis is the most stable.
Thank you for getting me through my masters in space engineering. This video has been extremely helpful when my lecturer failed to make me understand.

You're very welcome!

That's excellent, especially coming from an actual practitioner! Thank you for your support.
It seems some lessons where acquired by the little spinner in the space craft. Thankyou. Interesting.
