SUMMARY
The discussion focuses on calculating the Moment of Inertia for a point mass located at coordinates (3r, 1r) in the x-y plane. The user successfully determined the moments of inertia along the x and y axes but seeks clarification on calculating the z-axis moment. The formula for the moment of inertia about the z-axis is established as I_z = md^2, where d represents the distance from the z-axis, calculated as the hypotenuse of the triangle formed by the x and y components. This provides a clear method for determining the z-axis moment of inertia based on the point's position.
