(b) Element b can temporarily also be labelled with node numbers 1, 2 and 3, as element a. To avoid confusion, this is best done with the elements shown "exploded", as in Fig. 9.45. The alternative is to re-number the subscripts in the element stiffness matrix result from Example 9.5.

Performing the evaluations similar to part (a) leads to the required stiffness matrix for element b, namely symmetric
