(a) In this simple frame-work, members have different lengths, cross-sectional areas and materials, and are pin jointed. (i) Describe how you would develop the finite element equation of equilibrium in global form indicating the appropriate boundary conditions. (iii) If the members were welded at the joints, would the truss elements still be suitable for this problem? Give reasons. 2 F
