Simple derivation of the Equations of a Gyroscope

[QUOTE="PeroK, post: 6113086, member: 493650"] That's an interesting way to look at it. The gyroscope is supported on its stand. If there were no stand it would fall down! The vertical forces are balanced: gravity down from the centre of mass and the normal force up through the stand. This, however, creates a "torque", which you would normally expect to rotate the object about the point of contact on the stand. Torque creates a change in angular momentum. As the gyroscope is spinning you have to take the change in that spin angular momentum into account, when you see that the torque is in the wrong direction to rotate a spinning gyroscope down. The gyroscope is an example of the full vector nature of angular momentum. And that fact that you cannot ignore spin angular momentum in a rigid body. [/QUOTE]
