Query: Looping Pendulum: Theory, Simulation, and Experiment   The looping pendulum is a simple physical system consisting of two masses
connected by a string that passes over a rod. We derive equations of motion for
the looping pendulum using Newtonian mechanics, and show that these equations
can be solved numerically to give a good description of the system's dynamics.
The numerical solution captures complex aspects of the looping pendulum's
behavior, and is in good agreement with the experimental results.
