Question

Asked by: Nitro
Subject: A New Year quiz
Question: Happy New Year everyone.

As there has been little sign of new thought on gyrodynamics of late I thought I would pose a New Year quiz asking what you all think will occur with the application of a known force to a known mass. The video of this simple question is on my Jogglevision site here on YouTube:-

So as not to strain the old grey cells for too long, I shall put up the answering demo video around Burns Night (25th January coincidentally my birthday).

Kind regards

 Hi Nitro
Posted this on you tube. There are similarities here with Laithwaites demo of two pivoting gyros, at time 23:09 /https://www.youtube.com/watch?v=Pt9wTAL5KoU. where the mass of the gyros is displaced without a corresponding displacement of the frame.

In your apparatus when the gyros are not spinning, the spring will pull the Mass consisting of the arms and gyros, along the rail and at the same time the mass of the rail and frame etc will move towards the gyros. The C of G of the whole apparatus will remain in the same place.

When the gyros are spinning they will not react the force required to move the frame. The appearance will be that the gyros stay still and the frame moves.

Keep up the good work with Jogglevision!

 Alternatively!!!!!!!!

The exact opposite. Frame stays still and as in the Laithwaite experiment I cited the gyros will move. Which is what I meant to say first time round.

There will also be a reaction to the angular motion of the arms about the pivot which should cause some precession about the long axis of the frame.

It will give conclusive proof that the current paradigm is flawed.

When Richard P. Feynman wrote "It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong."

He lied.
