function y = QuadraticBarElementStresses(k, u, A)
%QuadraticBarElementStresses   This function returns the element  
%                              nodal stress vector given the element   
%                              stiffness matrix k, the element nodal 
%                              displacement vector u, and the 
%                              cross-sectional area A.
y = k * u/A;
