 along the chain.  The quality of this assumption depends on your
 particular chain.  For example, a damped spring thermalizes on a
 timescale of order $\tau = 1/\gamma$ where the damping ratio $\gamma

 frequency $\omega_0 \equiv \sqrt{k/m}$, $\zeta \equiv b/2\sqrt{km}$,
 and $b$ sets the drag $F_b = -bv$.  For our cantilevers $\tau$ is
 on the order of milliseconds, which is longer than a timestep.
