  1. 1. Dynamics of a complex mechanical pendulum : and its dependence on energy

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Niclas Löfvenmark; [2021]
    Keywords : ;

    Abstract : In this thesis we analyze the motion of the double pendulum in which the first rod has a distributed mass and the second is a light rod with a linked spring attached to a point mass. The dynamics of the system is modelled in Maple using the Sophia package and Lagrangian mechanics. Trajectories, phase portraits, conservation of energy etc. READ MORE
