The centre of the gravity’s location and the weight of the composite body is needed to be known. This means that if both of the quantities of the composite body is known then the moment of inertia of the body can be altered. Thus both are very important things to be known about the composite bodies.

Weight of the body
The mass moment of inertia of a composite material is a measure of its resistance to rotational motion around a particular axis. It depends on the distribution of mass within the material and the distance of each mass element from the axis of rotation. In order to vary the mass moment of inertia, two factors need to be known, one of which is the weight of the body.
Definition of Mass Moment of Inertia
Before delving into the weight of the body as a factor, let's briefly define mass moment of inertia. Mass moment of inertia, also known as the second moment of mass or the rotational inertia, is a property of a body that determines its resistance to rotational motion about a particular axis. It is calculated by summing the products of the mass of each particle in the body and the square of its perpendicular distance from the axis of rotation.
Understanding the Weight of the Body
The weight of an object is the force exerted on it due to gravity. It is equal to the mass of the object multiplied by the acceleration due to gravity. The weight of the body plays a crucial role in determining its mass moment of inertia because it affects the distribution of mass within the body.
Effect of Weight on Mass Distribution
The weight of a body influences the location of its centroid or center of mass. The centroid is the point through which the entire weight of the body acts. For a uniform density body, the centroid coincides with the center of mass. However, for composite materials with varying densities, the centroid may not align with the center of mass.
Impact on Mass Moment of Inertia
The location of the centroid of gravity affects the distribution of mass within the body, which in turn influences the mass moment of inertia. By varying the weight of the body, the position of its centroid can be adjusted, thereby altering the mass distribution and the resulting mass moment of inertia.
Conclusion
In conclusion, the weight of the body is one of the factors that need to be known in order to vary the mass moment of inertia of a composite material. The weight affects the location of the centroid of gravity, which in turn affects the mass distribution within the body and consequently the mass moment of inertia.
