    Gyroscopic Mechanisms [Related Components, Geometry, Mass, Atmospheric Pressure]

    Gyroscopic Mechanisms [Related Components, Geometry, Mass, Atmospheric Pressure]

    A Presentation On Gyroscopic Effects By Professor Eric Laithwaite.



    https://www.youtube.com/watch?v=OpCEJxO6V9g


    In the demonstration at 35:23 he demonstrates the gyroscope suspended on a string moving in a wide orbit (around the strings suspension point) while the gyroscope is rotating. The gyroscope at this point is at a high RPM and the gyroscopes axle is perpendicular to the string. Later in the same demonstration the gyroscope's orbit (around the strings suspension point) is less wide (smaller), while the RPM of the gyroscope is significantly less by comparison to the first example (with a wide orbit), however the gyroscope remains perpendicular to the string.

    In other words the orbit being large and the RPM being high and the orbit being small with a low RPM both result in the same position of the gyroscope (perpendicular to the string).



    Has anyone got any further related comments on this demonstration by Eric Laithwaite?

    I enjoyed this book not a college level book but a fun read

    The whole video makes me think. I did not know he had worked on Magnetic levitation systems.

    Space has inertia, as do gravitional forces. F=m.g, F = m.a, is for DC in electrical terms. V= I.R, more completely V=I.Z, Force and Potential can be viewed as the same thing.

    V = R.i + L.di/dt + C. integral i.dt ,

    F = m.a + m.da/dt + m. integral a.dt

    I need to have a deep think and. Do you have any of laithwaites maths he mentioned.

    Hey Andy,


    In the demonstration at 35:23 his mechanism is defiantly not magnetic or electric when it is functioning. It is simply a rotating gyroscope on the end of a string. Although there is a documentary about the Eric Laithwaite where he develops a magnetic levitation system, show levitating a metal ball, the clip is at the end of the documentary.

    I do not have any of the maths related to the presentation on gyroscopes although if you wish I can provide you with some of my own related to the 35:23 demonstration.

The technology was sold to the Japanese who went on and developed it. They now have an excellent rail service whereas the British have not.

    If you have some maths on the Gyro I would appreciate it, The book Tom recommended above only goes over basic rotational physics. Dont be concerned about using scary maths, I still understand it from school.

    I found this link which may be useful.

    Hi Andy,

    My gyroscopic physics is based upon a slightly different set of underlying principles.

    The fundamental and most important is that one side of a gyroscope/circular disc moving forwards through space while rotating moves at a slower speed that the velocity of the gyroscopes/disc central point while the other side moves at a greater velocity that the gyroscope's/disc's central point. Ultimately the gyroscope/disc's central point moves at the same velocity as all point on the gyroscope/disc do when it is not rotating. However upon addition of rotation from the previously stated setup the only point on the gyroscope/disc which remains at its previous velocity into rotation is the central point.

    Someone produced a design which consisted of

    1. A square platform, about 2 foot square
    2. Motors and flywheels mounted on the edges of this square, turning in same direction, plane parallel to edge.
    3. The entire system is made to rotate in its plane
    4. The entire system then loses weight.

    Can anyone find this work? Does anyone know how to calculate the weight loss as a function of the flywheel masses, rotational spee4ds etc?

    These mechanisms are dependent upon rotation of a disc which is moving upon a curved trajectory. The device you have mentioned rely's upon the curved trajectory of the planet, upon rotation of the flywheels the mass of the vehicle is effected. Gravity then shall exert a different quantity of force upon the flywheel when its mass is lower so as to allow it to fall at the same rate. However when the object is prevented from falling the actual force exerted on the flywheel can be measured. The direction (clockwise or counter clockwise) the flywheel rotates determines weather the mass increases or decreases as a result of either manipulation of curvature (of trajectory) or RPM.
