Asked by: Hajo Ehlers
Subject: Just say hello
Question: Hi
i an from Germany and having interest on Reactionless drives and gyros.
Currently i am trying to build a small experiment to see if the "weight" of a gyro ( incl. the 3 leg stable gimbal platform ) will increase or not if it gets accelerated in the plane of the gyro axis.

http://www.gyroscope.com/images/thumbnails/GIMBALS(2)-450.jpg ( I think i should supply a self made image )

Thus the whole gyro incl. the platform will be rotated/rotating

Later i would like to increase the speed of the rotation of the "whole" gyro and using a lower speed of the gyro itself because now centrifugal forces come into play.


I come alomg http://mb-soft.com/public3/gravit33.html where the question is rasied if "Conservation of Angular Momentum" is always a valid assumption.

 Hello Hajo

I took a quick look at the site


Correct conclusion, Conservation of Momentum is a general rule to which exceptions can be shown, not an immutable law.
He is wrong about precession. There is no energy exchange in a gyroscope moving from rest to precession. The gyroscope drop he refers to is a downward precession that provides the torque required to accelerate the inert mass of the gyroscope (the cage, bearings, shaft, etc)

He also does not differentiate between the offset gyroscope, where the mass orbits a point and the earth which rotates about its own axis.

This article by C Johnson, Theoretical Physicist, Physics Degree from Univ of Chicago shows how difficult the study of the offset gyroscope can be. He is a prolific, well educated and seemingly well informed writer, yet makes a basic error at the start.

Offset Gyroscopes produce a number of effects which clearly show that neither angular nor linear momentum are conserved, however these will not be demonstrated by your initial experiment.

This will definitely affect your proposed experiment.
