Hi!(adsbygoogle = window.adsbygoogle || []).push({});

The moment of inertia of solid sphere is 2/5 mr^2. However, when the sphere spins at light velocity, some articles state the moment of inertia is equal to 1/2 mr^2. However, no derivation is found in those articles.

Would you suggest some articles / textbooks which show the derivation of the moment of inertia equal to 1/2 mr^2?
