  "abstract": "We construct a hydrodynamic theory of the effect of chiral and active force densities on three-dimensional uniaxial solids. We show that in a fixed background medium active chiral force densities---that arise at lower order in gradients than odd elasticity---generically destabilise the solid state. We further show this active instability also affects isotropic chiral solids in an anisotropic medium, a situation that is relevant for cell clusters moving through the extracellular matrix. Interestingly, the instability is eliminated in a higher-symmetry solid, known as the polar elastomer; indeed, we show that chirality does not affect the leading-order mechanics of such materials. We further demonstrate that momentum-conserving polar active solids have two chiral odd elasticities in contrast to the one discussed for two-dimensional solids. However, we again find that the higher symmetry of polar elastomers eliminates one of these with the remaining one being equivalent to the two-dimensional odd elastic force density. Our results should apply to numerous biological and condensed matter systems.",
