Thanks tiny-tim, The problem for me is that you are using the formula 1/2 Iω² = Σ (1/2) m_{i}v_{i}², which is the sum of kinetic energies (due to curvilinear translation) of the particles of which the rigid body is thought composed of. But in reality the parts have an angular velocity the...

A rigid body is usually modeled as a large collection of particles in a fixed arrangement. Being particles, they by definition have no size so they cannot undergo rotation about their own axes as that does not make sense. All kinetic equations for rigid bodies are derived from this model, and...
