Rigid Body

A rigid body is an object which does not change its shape or undergo any significant deformation due to an external force or movement. Mathematically speaking, the distance between any two points inside the body doesn't change in any situation.

Rigid Body Dynamics

Rigid bodies are defined as inelastic shapes with negligible deformation, giving them an unchanging center of mass. It is also generally assumed that the mass of a rigid body is uniformly distributed. This property of rigid bodies comes in handy when we deal with concepts like momentum, angular momentum, force and torque. The study of these properties – viz., force, torque, momentum, and angular momentum – of a rigid body, is collectively known as rigid body dynamics (RBD).

Question

### Problem Description

Two uniform spheres, each with mass \( M \) and radius \( R_0 \), are connected by a thin (massless) rod of length \( 2R_0 \) such that the centers of the spheres are \( 4R_0 \) apart.

### Diagram

The diagram shows two spheres of equal size, labeled with radius \( R_0 \), connected by a straight rod. The rod's total length is indicated as \( 2R_0 \), and the distance between the centers of the spheres is marked as \( 4R_0 \).

### Questions

(a) Determine the moment of inertia of this system about an axis perpendicular to the rod at its center.

(b) Calculate the percent error if the masses of each sphere were assumed to be concentrated at their centers.

(c) Calculate the percent error if the rod itself has mass \( M \).

This setup involves understanding concepts of rotational dynamics and assumes familiarity with calculating moments of inertia and error analysis in physics.
