Also, it might help to explain why you know there is a difference between the Hamiltonian and the energy, and whether you know what the difference is. Anyways, the fact that the rod is driven to always rotate at a fixed angular frequency is probably where your "missing" energy comes from, but it's hard to say without seeing more about the system. | |
