Why most of the mass of a flywheel is concentrated at the rim?

Expert Answer:

Most of the mass of a flywheel is concentrated at the rim so as to have moment of inertia same for the whole mass. If such a wheel gains or loses rotational energy, the change in the angular velocity is very small. Thus, a flywheel helps to maintain uniform motion.
