Case.

Develop a potential energy function for the system illustrated in
the figure.

Develop the contour and surface graphs using matlab and minimize
the potential energy function to determine the equilibrium
displacements x_{1} and x_{2} given the
forcing function F = 100 N, and parameters ka = 20 and kb = 5
N/m.

  tPlease Do Like, if it helps!! 😃   Consider the function representing the potential energy can be expressed in the following way: PE=0.5pi_(a)x_(1)^(2)+0.5pi_(b)(x_(1)-x_(2))^(2)-Fx_(2)       Thus, the MATLAB script for generating the plot for the above expressed potential energy function can be written as:     Program: KA=20;KB=15;F=100; x=linspace(0,10,20);y=linspace(0,20,40); [x1,x2] = meshgrid(x,y); Z=0.5*KA*x1.^2+0.5*KB*(x2-x1).^2-F*x2; subplot(1,2,1); cas=contour(x1,x2,Z);clabel(c ...
