From: Anisotropic friction: assessment of force components and resulting trajectories

Fig. 5

Polar plot of the frictional force, F t -plot, and resulting trajectory – We report here, in the frame of reference attached to the rotating table, F t and ρ (in arbitrary units). The dashed line corresponds to the numerical trajectory obtained using the experimental force. We observe that the trajectory is mainly elongated in the direction exhibiting the smaller value of the friction force, but that F t and ρ do not exhibit the same symmetries due to the asymmetry introduced by the driving [The concentric dotted circles are used as guides to the eye, a=12.6 cm and R=19.3 cm]
