- Finding the moment of inertia for an Spinning top
- Relevant Equations
- L = r x F
I hope you guys can help me with this problem..
A top in the form of a flat, circular disc spins on a shaft that is inclined at an angle alpha to the vertical.
Now I have to find the moment of inertia I for the disc about its centre on the shaft.
My attempt was building I with spherical coordinates (r= length of the shaft, phi= \omega t , theta= angle to the vertical) But I think that's just the Point the vector r is pointing to the center of the disc ?![Roll Eyes :rolleyes: :rolleyes:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
