         where the components of the symmetric matrix are:


























         As Eq. (2.99) indicates it, bending and torsional are coupled this time, unlike
         the case of the hollow rectangular design.

          2.3.3  Trapezoid Design

             Figure 2.20 (a)  is the  simplified  model of  a  hollow  trapezoid
          microcantilever’s. The stiffnesses which are of interest are found in a similar
          fashion to the ones determined for the triangular configuration. The coupler
          2-4 is considered rigid.
