I'm not concerned about it being easy to implement. I need the most efficient method of keeping that wheel spinning regardless of the contstruction.
That's also why I asked for other ideas :)
I see... Let's take a case where I'm sitting on a chair holding the spinning wheel at arms length. I'm twisting the wheel so I will rotate on the chair. Now I just need the wheel to keep spinning to keep rotating.
What then would require the least amount of energy?
Hello.
This question has kept me up all night: What mechanism would keep a wheel spinning using as little electrical energy as possible?
Let's say we have a toy car (could be anything that involves a wheel) that is already in motion and moving with a constant velocity. What would you build...
The r is the radius from the string to the wheel. If I extend the radius the precession rate will go up. It should be the same with my arms right? If I were able to extend them :)

So basically I could use the same equation as for the situation where the wheel is hangin by the string?
So I find for the precession rate:
w = (r * T)/(I * s) , where r is the length of my arms, T is the torque I apply, I is the moment of inertia of the wheel and s is the spin frequency of...
Hi.
I am working on a little project involving precession and I'm having a hard time figuring this one out.
I am sitting on a chair hold a spinning bycicle wheel in my arms. When I twist the wheel to the side I will start to spin.
What governs how fast I will spin? What is the equation...
