# Difference between revisions of "Kelvin's medium"

Kelvin's one-dimensional medium is a chain consisting of masses interacting via a pair torque potential. In this example the masses are visualized by rods. The masses interact via the torque potential:

,

where is the interaction constant, , are the unit vectors bound to the masses. The interaction torque has the form:

Then the motion equation for the k-th particle is as follows:
