Moment of Inertia Study Materials
Principal Moment of Inertia.
The perpendicular axes about which product of inertia is zero are called “Principal axes” and the moments of inertia with respect to these axes are called as principal moments of inertia.
Among two values of moments of inertia about the set of principal axes. One will be maximum and the other will be minimum. The maximum moment of inertia is known as Major principal moment of inertia and the minimum moment of inertia is known as Minor principal moment of inertia.

Mass moment of inertia:
The moment of inertia of solid figure is generally referred as “Mass moment of inertia”. It is denoted by the symbol (I)mass or Simply Im.
Kinematics of particles:
Kinematics is the study of motion of a moving body without considering the forces which cause the motion and kinetics is the study of motion of a moving body with also considering the external forces which cause the motion.
Types of plane motion:
- Rectilinear motion
- Curvilinear motion
The motion of a particle along a straight line is known as rectilinear motion (or straight line motion).
