CG Showcase of Overbalanced Wheel

Trajectories of object1/object2 are differents like image showing. Force from friction is F on object1 and -F on object2. Why energy must be the same if trajectories are differents ?

Different frequencies give different results because object2 moves differently. All forces are stable if frequency is lower than 2400 Hz.

@helloha: you knows WM2D, can you test my model on this software ?

Sum of energy change when trajectory change.

a-XXX XXVIII. trying my hands on wm2d, model based on rc4's design   

@rc4: i have problem opening the .phz file for the moment (due to my computer hardware/software issues),
so the wm2d model is based purely on the image you upload.
