Web1 Hamiltonian formalism for the double pendulum (10 points) Consider a double pendulum that consists of two massless rods of lengthl1andl2with masses m1andm2attached to their ends. The ﬂrst pendulum is attached to a ﬂxed point and can freely swing about it. The second pendulum is attached to the end of the ﬂrst one and can freely swing, too. The Hamiltonian can induce a symplectic structure on a smooth even-dimensional manifold M in several equivalent ways, the best known being the following: As a closed nondegenerate symplectic 2-form ω. According to the Darboux's theorem, in a small neighbourhood around any point on M there exist suitable local coordinates (canonical or symplectic coordinates) in which the symplectic form becomes:
