Two disks are rotating about the same axis. Disk A has a moment of inertia of 3.1 kg · m2 and an angular velocity of +8.0 rad/s. Disk B is rotating with an angular velocity of -9.3 rad/s. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit with an angular velocity of -2.2 rad/s. The axis of rotation for this unit is the same as that for...

Moment of Inertia To find the moment of inertia of different objects and to observe the changes in angular acceleration relative to changing moments of inertia. To also learn how to use calipers in making precise measurements The momentum of inertia of an object is calculated as I=∑mr^2 If the object in question rotates around a central point, then it can be considered a "point mass", and its moment of inertia is simply,  I=mr^2 where r is from the central point...
