We construct the orthonormal bases of the Cosserat subspace ũ-1 corresponding to the eigenvalue of infinite multiplicity ω̃=-1 for the first boundary value problems of elasticity for a solid cylinder and a cylindrical rigid inclusion. These bases involve the Jacobi polynomials with different weight functions. An example of non-harmonic heat flow past a cylindrical rigid inclusion shows that the sequence of ũ-1 converges fast, thus, the Cosserat spectrum theory is an efficient method for solving elasticity problems of general body force or boundary loading.
