In a similar fashion to the case study described in Sec. 16.4, develop the potential energy function for the system depicted in Fig. P16.32. Develop contour and surface plots in MATLAB. Minimize the potential energy function in order to determine the equilibrium displacements x1 and x2 given the forcing function F = 100 N, and the parameter ka = 20 and kb = 15 N/m?
