Question

Calculate mass of inertia about an axis tangent to the given solid sphere but axis is parallel to the central axis.

Answer 1

moment of inertia of solid sphere about central axis =2/5*Mr^2
moment of inertia about an axis tangent to sphere parallel to central axis
Using parallel axis theorem

=2/5Mr^2+Mh^2
=2/5Mr^2+Mr^2
=7/5Mr^2
