Bicycle Display Rack

A bicycle wheel is suspended from one of end of its axie by a rope, and spun up by hand. The wheel’s axle is then placed horizontally and the free end of the axle processes about the supported end.

The gyroscope seems to defy gravity because the torque created by the spinning wheel counteracts the torque due to gravity. Gyroscopes have been used through history for varied uses such as stabilizing spacecraft or for guidance systems on ships and missiles.

  1. Angular momentum is a fine label for a natural phenomenon with a precise mathematical formula but it explains little. I believe I do a better job of demonstrating that gravity consists of locally generated angular lines of radiant attractive force with my "1Gravity" video, also on YouTube.

  2. There are lot of misinterpretations in physics with regard to Angular Momentum. That is because some accepted faulty theorizations remained unchallenged for centuries.What is the use of hand rules if the founder himself had a clear idea of the mechanism behind the phenomenon? Erection of a hanged cycle wheel can be explained easily without any reference to the gloomy theory of 'Conservation of Angular Momentum'.

    What are the parameters which do matter upon the phenomenon?
     1. Rotating speed of the wheel
    2. mass of the rotating part of the wheel
    3. Radius of the bearing (ball bearing, roller bearing or sleeve bearing etc.)
    4. Friction of the bearing
    5. Angle of inclination of the axle
    You would agree with no arguments on 1st and 2nd parameters because the relation is clear enough. But about the 3rd reason you would argue ‘How radius of the bearing does matter’ with it?  
    The perpendicular force ’Fp’ is a centrifugal force and it depends on the distance from rotating axis to the frictional surface on which the wheel is rolling. The entire wheel load is shouldered by the axle at the top region of the bearing as shown in the figure-04.

    Even if we don’t notice it, the wheel is just rolling over that point while rotating. The ‘action’ is the resistance of the bearing and ‘reaction’ is the centrifugal force due to rolling. The force of reaction proportionate to shift of rolling surface from the rotating axis and therefore radius of the racer bearing becomes important. 

    You can observe it by yourself doing the same experiment by use of a very small bearing fixed to a very lean axle and observe the wheel would not be erected.   

    Then you may question ‘how friction of the bearing affects upon this matter? 

    Frictional force is the ‘action’ applied against the rotary system. If the action is weak then the reaction too becomes weak. 

    Therefore use a 100% frictionless racer (if possible) and observe the wheel would not be erected as a proof of the theory.  Also use an old corroded racer bearing and observe how easily the wheel is erected.   

    “What is the importance of the inclination of the axel?” then you may ask. 

    I can answer this by a similar question such as, “why don’t you hang your apparatus sharply vertical?”
    You can weld a hook at the end of the axle and hang the thing sharply vertical and then you would observe no erection at all. And why is that? That is because the wheel weight should be loaded only upon one side of the axle to create a perpendicular reaction. Therefore no erecting force is induced within the wheel whereas the axle is kept sharply vertical. 

    You can do the experiment in a space laboratory under zero gravity conditions.  However much speedy the wheel could be rotated there no erection would be observed because no wheel load is applied upon the axle. Therefore give up those unnecessary hand rules and gloomy theorizations whence things could be clearly explained mechanically. (pl ref 'Theory of Action & Perpendicular Reaction' for more)

  3. Take the rope off. Set the wheel on the table with the axle pointed up-down.  Then spin the wheel at about 1,000,000rpm. (will need to make the wheel a bit stronger.) It will rise up off the table. (assuming it is light enough and that the exterior of the wheel is traveling faster than 18,000 mph or Escape Velocity.) At that rpm it will start to noticeably warp space time. Do the math.
