Four springs, each with force constant k and unstretched length l 0 , are connected as shown in Fig. 11-35. The springs obey Eq. 11-I5 for both stretching and compression. Show that the work required to move the point of attachment from the equilibrium position in a straight line to the point x, y (with x 0 and y 0 ) is W = kd 2 , where d 2 = x 2 + y 2 .
