reaction forces at pins 1, 2, and 3, and check to see whether equilibrium is satisfied.
Formulate the stiffness matrix with factor EA// by the finite element method.
10-12 For the pinned square truss of Fig. PlO-12, determine the element stiffness matrices
in global coordinates and indicate how they are assembled for the entire structure.
10-13 For the pinned truss of Fig. PlO-13, there are just three orientations of the elements.
Determine the stiffness matrix for each orientation and indicate how each element
matrix is assembled in the global system.

10-14 Using two elements, determine the deflection and slope at midspan of a uniform
beam, fixed at both ends, when loaded as shown in Fig. PlO-14.
