Rotational Inertia and Moment of Inertia Before we can consider the rotation of anything other than a point mass like the one in Figure 2, we must extend the idea of rotational inertia to all types of objects. To expand our concept of rotational inertia, we define themoment of inertiaIof...

The rotational lines will be distributed in a way that depends on the ratio of the moments of inertia of the principal axes of the molecule. Thus there will be multiplets for lines which are closely spaced in energy and which can be strongly radiatively coupled (see discussion of masers). ...
For a hollow cylinder of mass M and radius R, the moment of inertia is I = MR2. For a solid cylinder, I = 12MR2. Force is replaced by a “rotational force” that depends upon the force and its placement from the axis of rotation; this is called a torque T. While a small ...

and the axis of rotation, the greater the rotational inertia. The tight- rope walker shown in Figure 12.2 increases his rotational inertia by holding a long pole, allowing him to resist rotation. think! FIGURE 12.1 Rotational inertia depends on the distance of mass from the axis of rotati...
Rotational Energy and Moment of Inertia of a nitrogen molecule Problem 10-58a: The equilibrium separation between the nuclei of the nitrogen molecule (N2) is 0.190 nm and the mass of each nitrogen nucleus is 14.0 u, where u = 1.66E-27 kg. For rotational energies, the total energy is due...

In case of external torques, we could link them to the variation in time of the kinetic energy. For a given inertia matrix, kinetic energy, and angular momentum of the body, we can define the so-called inertia ellipsoid, kinetic energy ellipsoid, and angular momentum ellipsoid [1,4]. A ...
