Solving a classical problem using quantum physics

vishal007win

I came across a discussion on net recently, where projectile motion was solved using the quantum mechanical approach.

I have already seen solution of the vibrations in string using quantum mechanics.
I want to ask can i use quantum mechanics to find the vibrations in ring. if there is any text on this stuff available, please let me know. Need a little guidance before starting the rigorous calculation process.
Thank you

Wouldn't it be exactly the same as for the string except with continuous boundary conditions on the edge.

sorry i forgot to mention. By ring it meant a solid ring, whose vibration analysis will require the knowledge of solid mechanics. So now you see nature of problem differs entirely.
