Ok an error in the equation Iy which was noted by Tim and still took my half an hour of brain scratching to work out for myself. the tern ax should be (a-1)x also note that the x is in fact the matissa m , I just called it x as I had to use the value x for it to work in desmos the graphing calculator. I will cover this error and the derivation if Iy in another video.

Taking a bit of a 'tangent' here , pardon the pun. Extending the idea of a magic number to a magic line. Not sure if I am going anywhere with it , but the mathematics is interesting so let's travel down this road for a while and see where it takes us.
