Some equations of linear elasticity are developed, including those

specific to certain actuator structures considered in formation

theory. The invariance of the strain-energy under the transformation

from rectangular to spherical coordinates is then established for use

in two specific formation problems. The first problem, involving an

elastic structure with a cylindrical equilibrium configuration, is

formulated in two dimensions using polar coordinates. It is shown

that $L^2$ controls suffice to obtain boundary displacements in

$H^{1/2}$. The second problem has a spherical equilibrium

configuration and utilizes the elastic equations in spherical

coordinates. Results similar to those obtained in the two dimensional

case are indicated for the three dimensional problem.
