Any mechanical system consists of mechanical elements. There are three types of
basic elements in mechanical systems:
Inertia elements
Spring elements
Dampers elements
Inertia Elements.Inertia Elements.Inertia Elements.Inertia Elements. Mass and moment of inertia. Inertia may be
defined as the change in force (torque) required to make a unit change in
acceleration (angular acceleration). That is,
= 2
