determine the fsg matrix at s = 0, t = 0 using the isoparametric formulation vivid in Section 10.4. (Also see Example 10.5.) Let E = 30 106 psi and n = 0:3.

2. For the three-noded bar (Figure P10–1), what Gaussian quadrature government (how sundry Gauss points) would you praise to evaluate the sti¤ness matrix? Why?
