AI Thread Summary
To destabilize a gyroscope, a force must be applied that causes a change in the orientation of its rotational axis, typically defined as precession. Even a small force applied off the spin axis can initiate precession. In the example of a 10 kg iron wheel rotating at 1 rotation per second, the specific force required to achieve a 30-degree shift in orientation depends on various factors including the gyroscope's speed and mass distribution. Understanding the mechanics of gyroscopic motion is crucial for calculating the exact force needed. This discussion highlights the importance of defining "destabilize" in the context of gyroscopic behavior.

When a Gyroscope is Running, How much Force need to apply it to destabilize(change in the orientation of the rotational axis, say 30 degrees from the original position) the gyroscope ?.

For Example. When a Iron Wheel of diameter 30 cm and 10kg rotating at a speed of 1 rotation/sec in a gyroscope. How much Force need to apply to destabilize the Gyroscope.

You must define "destablilize". If you mean "precess" then any amount of force, no matter how small, applied anywhere but in line with the spin axis, will cause the gyroscope to begin precessing.
 
Thanks billslugg. I added the meaning of destabilize.

See #2 above.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
