A prescribed local linear Maxwell <force> law filters a harmonic drag amplitude by $(1+i\omega\lambda)^{-1}$. For periodic states its time derivative has zero mean, so the mean <force> equals the mean driving <force>. Leading harmonic power is reduced by $[1+(\omega\lambda)^2]^{-1}$, as elastic storage changes the in-phase dissipative response.
