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 = 100/6 and kb = 15 N/m.
syms x1 x2 F = 100; ka = 100/6; kb = 15; PE= 0.5*ka*x1^2+0.5*kb*x2^2-F*(x1+x2) fcontour(PE) fsurf(PE)
