A ring and disc have the same mass and radius.What is the ratio of their moment of inertia about their axis of symmetry?

What is the moment of inertia of a disc about their diameters?

What is the moment of inertia of a ring

Define perpendicular axis theorem of moment of inertia.

What is physical significnce of moment of inertia?

What is the concept of inertia mass?

Torques of equal magnitude are applied to a hollow cylinder and a solid sphere, both having the same mass and radius. Hie cylinder is free to rotate about its standard axis of symmetry, and the sphere is free to rotate about an axis passing through its centre. Which of the two will acquire a greater angular speed after a given time.

On what factors does the moment of inertia depend?
