In this study the validity of a new mechanical damper, the rotational inertia damper, is investigated through numerical analysis. Once installed between stories, the damper provides effective mass to the structure expressed as the rotational mass moment of inertia multiplied by the inverse of the bal...

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...
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 ...

Moment of Inertia As you just learned, spinning the same object around a different axis of rotation, or changing the radius, can make the motion more or less difficult. A natural extension of this concept is that similarly shaped objects with different distributions of mass have...
