Im really not sure how to solve this. For the oscillations themself the angular frequency is w=sqrt(k/m)? Although this is not going to be the angular frequency of the cylinder. Im looking through my book and all my notes, I really cant figure out how to relate the angular frequency of the wheel to the oscillations. for this problem Ive been trying to use w=sqrt((m*g*d)/I). Im not sure if Im on the right track, as Im not sure what to use for d and Im still trying to calculate the moment of inertia. Am I correct in assuming that I is the sum of the moments of inertia on each side of the axis? So that you would have I =(1/2)(9.7)(1.326^2) + (1/2)(9.7)(2.57^2)? thanks for any help.
