SUMMARY
The discussion focuses on deriving the equations of motion for a compound pendulum with three degrees of freedom (DOF). The user is familiar with Lagrangian mechanics for simple pendulums and seeks clarification on whether the system is a 3D conical pendulum or a 2D plane pendulum composed of three interconnected rods. The compound pendulum is described as a single irregular body with a 3x3 inertia tensor, fixed at a point and capable of movement in a 3D rectangular coordinate system, characterized by rotational angles alpha, beta, and gamma.
