[2] is pretty cool article. It might be the first time I have understood optimization from a mechanics perspective correctly. Thanks for sharing. PS: there are still some errors in the blog I found (Theta, M (not m) in moving cart figure)

Thank you, that means a lot - you are right there are still some small errors that I need to go through and I'd be very grateful if you let me know of any more you find
