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

- ,

where

is an interaction constant, , are the unit vectors bound to the solids. The interaction torque is as follows:Then the motion equation of the k-th particle takes the form:
