 Moment of Inertia
The moment of inertia of a body is not only related to its mass but also the distribution of the mass throughout the body.
This concept of first mass moment is normally used in deriving the center of mass of a system of particles or a rigid body.
Thus, it would be more accurate to say that the moment of inertia of a rigid body reflects the mass distribution within the body with respect to the axis of rotation.

 Moment (physics) - Wikipedia, the free encyclopedia
For cases when the moment is the sum of individual "submoments", such as in rigid body dynamics where each particle of the body contribute to a moment, the axis change is the sum of a macroscopic and microscopic quantity,
The principle of moments is derived from Archimedes' discovery of the operating principle of the lever.
In physics, the moment of force (often just moment, though there are other quantities of that name such as moment of inertia) is a quantity that represents the magnitude of force applied to a rotational system at a distance from the axis of rotation.

 moment on Encyclopedia.com
The moment of inertia of a body about a point is the sum, for each particle in the body, of the mass of the particle and the square of its distance from the point.
If a force tends to rotate a body about some point, then the moment, or turning effect, is the product of the force and the distance from the point to the direction of the force.

 Moment of inertia
The moment of inertia of a body, which is always measured relative to a point of rotation, depends in general on the object's mass and on its shape.
Similarly when a spinning figure skater pulls her arms in to her body she places more of her body weight closer to the axis of rotation and decreases her moment of inertia.
In an extended object the parts that are further from the axis of rotation contribute more to the moment of inertia than the parts closer to the axis.

 Moment of Inertia
The moment of inertia of a body depends on the axis of rotation, and there can be three different moments of inertia about mutually perpendicular axes passing through the center of mass.
The moment of inertia is defined as the sum of the products obtained by multiplying the mass of each particle of matter in a given body by the square of its distance from the axis.
The axis may be internal or external to the body and may or may not be fixed.

 DistributionDefinition.doc
Here distribution refers to an action of supplying shares of proteins inside human body.
In biology the term distribution is applied to the distribution of proteins by a blood stream inside a human body.
Distribution is also an action of spreading or mode of being dispersed all over an area, as in “this distribution of temperature must have some influence on the shape of the hail stone.” The term distribution also means classification or division and arrangement, as in “the distribution of land into parishes” (11: 354).

In a frontal crash, the forces are distributed along the entire side of the infant's body, while a harness or body band keeps the baby in place during rebound or rollover.
It is therefore not necessary to move children out of their CR the moment they exceed either the weight specified or the recommended head or shoulder height.
Although the most upright position probably still provides the most effective overall restraint in terms of load distribution to appropriate bony structures, a certified reclined position may be used for a sleeping child or to make the CR conform to the enclosed angle of the vehicle seat for a tighter installation.

 Rigid Body Dynamics
The physical characteristics of a rigid body can be described by its inertial properties: mass and moment of inertia.
For this reason, a major portion of discussion will be dedicated to the inertial properties of the rigid body: moment of inertia and inertia tensor.
Therefore most of the equations for a system of particles are usable in the dynamics of a rigid body.

 Encyclopedia Excerpt- Pesso Boyden System Psychomotor (PBSP) - A Body Oriented Psychotherapy and Emotional Re-education Process
Although absorbed with this externally represented memory, the client is nonetheless able to use his/her new-found awareness of emotions, body sensations, and impulses as the motive force to express what is coming up from moment to moment.
PBSP "structures" employ the use of ideal figures who provide the client with tactile, motoric, visual and auditory input that can be used as material to construct, in the mind’s eye and in the mind’s body, an experience, parallel — but in healing contrast — to the original traumatic event.
It is a method that allows the physical, motoric, yet symbolic, expression of feelings that are deeply stored in the body from impressive past events.

The moment of inertia of a distributed mass is found by subdividing the body into infinitesimal point masses and integrating over the entire volume of the mass.
Your objective is to experimentally verify that the moment of inertia of a mass moving in a circle of radius R is proportional to the mass and proportional to the square of the radius of the circle.
If the moment of inertia is really directly proportional to the mass, as you expect, the graph should be a straight line (with some deviations due to indeterminate errors).

Body roll controller: a predicted (corrected) lateral acceleration signal is used to compute the total required anti-roll moment and its direction to keep the body flat in any transient (initial roll) and steady-state driving condition.
The primary function is controlling the lateral dynamics of the vehicle by adjusting the roll moment distribution to the actual driving condition.
The main components, the EHCU and the active stabilizer with the roll control actuator, are shown in Figures 2 and 3.
