    Motion Equations by Newton's Formalism for a Double Pendulum

    I already have the Lagragian. I want to obtain the same equations using Newton's formalism, so I did the free body diagrams: For m2, I found F2 (analysis in x) and I found the following equation (analysis in y): So, using F2 in the free body diagram for m1, the resultant equation does not...

    Motion Equations by Newton's Formalism for a Double Pendulum

    By Lagrange's formalism, the motion equations for double pendulum are: Using Newton's formalism I can't obtain the second equation. Anyone can help?
