I think similar questions have already been asked but they are just similar not same.
I completely agree with the fact that product moment of inertia is a physical quantity but i am not able to find a satisfactory(as per me) example which tells the actual reason behind why the mass distribution along y axis will resist rotation about x axis?
Does that mean when a body of arbitrary shape is rotated along y it will soon start having an angular acceleration along x too? I am not able to intuitively feel this. Shouldn't the body rotate normally, with only the mass distribution perpendicular to whatever axis it is rotating, effecting it?
Please correct me wherever i am wrong and suggest examples, links or videos to give it an intuitive feel.
P.S. I actually tried to search a lot before asking here. Any help would be great.
