Many MEM devices feature tether suspensions and it is known that the tethers induce a stiffening behavior. In this paper, we develop a model for a tether and, from it, establish several useful expressions for the nonlinear restoring forces and torques it provides. For a specific gyroscope, the expressions we find are compared to experimental results.
