Double gyroscope

( Adolf Cortel 2009) Double gyroscope. The weels can turn in the same or in opposite directions. When the angular momentum adds it behaves like a gyroscope. However, if the weels turn in opposite directions the angular momentum cancel and nothing particular is observed. This means that the magnitude responsible for the behaviour of a gyroscope (angular momentum) depends on the sense of rotation so, it is a vector

Dear Adolf, nice video. It neatly shows the additivity of angular momentum. However, you might want to change "and anything special is observed" to "nothing special is observed".

Cheers.

@Kloer5

Thanks for your kind comment. Of course, you're right and I'd like to change the sentence, but to do this I should edit the video again and upload it with another name . I also like this video very much because it clearly shows that the magnitude responsible for the behaviour of the giroscope is a vectorial one (angular momentum). The idea comes from Sutton's book (Demonstration Experiments in Physics). Regards.

@realisticHomeboy NO, I AM NOT A HOMOSEXUAL AND I HAVE NO INTEREST IN MEETING YOU.

THERE ARE GAY DATING SITES ON THE INTERNET WHICH ARE BETTER FOR YOUR NEEDS THAN YOUTUBE.

PLEASE STOP CONTACTING ME.

THANK YOU ONCE AGAIN AS I HAVE ASKED YOU TO STOP BEFORE.

Yes, precisely - sorry, didn't see that you got there yourself :o)

English is sometimes hard for us non-E-speakers, when it comes

to the finer details. I think that is what happened in this video.

@realisticHomeboy

I think he means "nothing special is observed", because the opposite angular momentums cancel each others out, so that the gyroscopic effect vanishes, unlike whenboth gyros spin in the same direction.

@realisticHomeboy Or you mean "nothing special is observed"?

Anyway, thanks for the video. It answered the question I needed answered.

[realisticHomeboy]

"anything special is observed" doesn't really make sense. You must mean "something special is observed"?
