Hi, I'm not sure if this belongs here or in general physics. Moderators please feel free to move this post if it is not in the right place. I have been perusing the internet looking for information related to the gyroscopic effect without much avail. I have detailed knowledge of linear physics, such as, force, momentum, acceleration and so on. I am hoping that someone here will volunteer to either teach me rotational physics or direct me to good sources. I know linear algebra, multivariable calculus and second-order differential equations well. I just need some help with the concepts. The gyroscopic effect and precession interests me the most. Why does rotation on one axis make rotations on a second axis more difficult? How much more difficult is it to rotate? Any online sources or just plain typed explanations would be appreciated. Thanks in advance, Bobby.
