A free-free solid beam is analyzed to determine the first axial and bending mode natural frequencies. For the
axial mode case use Householder eigenvalue extraction and for the bending mode case use subspace eigenvalue
extraction to extract the required eigenvalues. Examine the influence of rectangular, trapezoidal, and parallelogram
