Summary:

This video presents the code that animates (drawing moving rectangles) the simulation results of a 3-mass 4-spring system whose model was developed in video [moll3mod2EN] and whose simulation details (comparing ode45 and lsim) were discussed in video [moll3sim1EN].

A simpler animation of the oscillations of a single mass is presented at video [masmuAnimEN]; maybe you should view that one prior to this if you are not familiar with Matlab.

Here, we animate the vibration in both longitudinal and transverse form, to better understand how the system vibrates; examples of free response and forced response (three resonant vibration modes, whose resonant frequency computation is not in the scope of this video) are provided.
