Relation between moment of inertia and equivalent stiffness

Answer 1

Equivalent mass / moment of inertia including geared shafts. While we ... Therefore if the springs are in series combination, the equivalent stiffness is equal to the reciprocal of sum.is the moment of inertia of the beam's cross-sectional area about the neutral axis. The equivalent stiffness for the beam is the ratio of the applied load to the deflection ...

Answer 2

Rotational inertia is important in almost all physics problems that involve mass in rotational motion. It is used to calculate angular momentum and allows us to explain (via conservation of angular momentum) how rotational motion changes when the distribution of mass changes.
