1. The problem statement, all variables and given/known data A clock balance wheel has a period of oscillation of 0.250 s. The wheel is constructed so that its mass of 10.0 g is concentrated around a rim of radius 0.600 cm. a) What is the wheels moment of inertia? kg m^2 b) What is the torsion constant of the attached spring? N m / rad 2. Relevant equations I=mr^2 3. The attempt at a solution starting with part a) I have gone mr^2 and gotten 3.6x10^-7 so i assumed that answer didnt make sense, I thought it could be because it says the mass is concentrated around the rim so do i treat that as if it was a ring? If so I know that dI = dm r^2 so ∫dI = r^2 ⋅ ∫dm so I = r^2 M where M is the mass of the whole ring system. Am I correct in this working or was my first calculation correct ?
