Moment of Inertia of a Disk plus YouTube
The rotational inertia of a composite object is the sum of the rotational inertias of each component, all calculated about the same axis. Itotal = I1 +I2 +I3 +. (7.4.7) (7.4.7) I t o t a l = I 1 + I 2 + I 3 +.. So for a ring and a disk stacked upon each other and rotating about the symmetry axis of both, the rotational inertia is:
Simple trick to understand Moment of Inertia of a Thin Disk. JEE
For a single particle rotating around a fixed axis, this is straightforward to calculate. We can relate the angular velocity to the magnitude of the translational velocity using the relation vt = ωr v t = ω r, where r is the distance of the particle from the axis of rotation and vt v t is its tangential speed.

This last equation is the rotational analog of Newton's second law (F=ma), where torque is analogous to force, angular acceleration is analogous to translational acceleration, and mr 2 is analogous to mass (or inertia).The quantity mr 2 is called the rotational inertia or moment of inertia of a point mass m a distance r from the center of rotation..

Thus, the rotational inertia of a thin disk about an axis through its CM is the product of one-half the total mass of the disk and the square of its radius. Notice that the thickness of the disk does not effect its rotational inertia. A consequence of this fact is that a cyclinder has the same rotational inertia as a disk, when rotated about an.

I parallel-axis = 1 2 m d R 2 + m d ( L + R) 2. Adding the moment of inertia of the rod plus the moment of inertia of the disk with a shifted axis of rotation, we find the moment of inertia for the compound object to be. Itotal = 1 3mrL2 + 1 2mdR2 + md(L + R)2. I total = 1 3 m r L 2 + 1 2 m d R 2 + m d ( L + R) 2.

To develop the precise relationship among force, mass, radius, and angular acceleration, consider what happens if we exert a force F F on a point mass m m that is at a distance r r from a pivot point, as shown in Figure 10.10. Because the force is perpendicular to r r, an acceleration a = F m a = F m is obtained in the direction of F F.

Rotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis. Rotational inertia plays a similar role in rotational mechanics to mass in linear mechanics.
How to derive the moment of inertia of a disk YouTube
Theoretically, the rotational inertia, I, of a ring about its center of mass is given by: 2 2 = --M R + R ( 1 2 where M is the mass of the ring, R1 is the inner radius of the ring, and R2 is the outer radius of the ring. See Figure 11.1. The rotational inertia of a disk about its center of mass is given by: I = - 1 -MR2 2

This last equation is the rotational analog of Newton's second law F = ma F = m a, where torque is analogous to force, angular acceleration is analogous to translational acceleration, and mr2 m r 2 is analogous to mass (or inertia). The quantity mr2 m r 2 is called the rotational inertia or moment.

Moment of Inertia of a Disk. The moment of inertia, which is also denoted by the letter "i", measures the extent to which resistance of an object is rotational acceleration about a particular axis, and is the rotational analog to mass. \ [ML^2\] (mass×length2) is the unit of the dimension of Mass moments of inertia.
NOVA Physics Rotational Inertia of a Uniform Disk YouTube
Moment of inertia, denoted by I, measures the extent to which an object resists rotational acceleration about a particular axis, it is the rotational analogue to mass (which determines an object's resistance to linear acceleration ). The moments of inertia of a mass have units of dimension ML 2 ( [mass] × [length] 2 ).
Rotationl dynamic lecture_12./Moment of inertia of a disc YouTube
The moment of inertia, otherwise known as the mass moment of inertia, angular mass, second moment of mass, or most accurately, rotational inertia, of a rigid body is a quantity that determines the torque needed for a desired angular acceleration about a rotational axis, akin to how mass determines the force needed for a desired acceleration.
