Simply put, the polar moment of inertia is a shaft or beam's resistance to being distorted by torsion, as a function of its shape. ... The greater the magnitude of the polar moment of inertia, the greater the torsional resistance of the object.

Flywheel is a solid disc mounted on the shaft of machines such as turbines, steam engines, diesel engines etc. When the load of such machines suddenly increases or decreases its function is to minimize the speed fluctuations which occurs during the working of machines.

The Flywheel acquires kinetic energy from the machines. The capacity of storing of KE (kinetic energy) depend on the rotational inertia of the flywheel. This rotational inertia is called as Moment of Inertia(or polar mass moment) of rotating object namely wheels.

The moment of inertia of  body is defined as the measure of object’s resistance to the changes of its rotation.

Hope it helps.
