MARAZ, E  y  BURGOA, O. SIMULATION OF THE MOVEMENT OF A DOUBLE PENDULUM IN A VISCOUS MEDIUM. Revista Boliviana de Física [online]. 2014, vol.25, n.25, pp.27-30. ISSN 1562-3823.

We present the movement equations of a double pendulum with a resistance proportional to the velocity using the lagrangian formalism (the double pendulum system is simulated with the "yabasic" language). We solve these equations using the Runge-Kutta numerical method; as a result, we calculate the resistance coefficient of the medium using experimental data taken from a simple pendulum as a reference. Subject headings: Lagrangian and Hamiltonian mechanics - Numerical simulation; solution of equations
