Problem 11.5: Give the connectivity matrices and the specified primary degrees of freedom for the plane elasticity problems given in Fig. P11.2. Give only the first three rows of the connectivity matrix.

General Note: A pin-type connection implies that both components displacement are zero, whereas a roller support indicates the displacement normal to the wall is zero. In the following problems denote the horizontal and vertical displacements, respectively, at the global node of the mesh, and and denotes the horizontal and vertical forces, respectively, at the global node of the mesh.
