Question
What is the radius of gyration of a right circular cone of base radius R for rotation about the central symmetry axis of the cone?
Short Note
Solution
A solid right circular cone with mass M and base radius R has a moment of inertia of `3/10 MR^2` about its central symmetry axis. Therefore, the radius of gyration about that axis is k = `sqrt(3/10 R)`.
