A 20 m long simply supported beam with an elastic modulus of
E = 1 GPa can be modeled by two elements as illustrated in Figure 11.37. A 1 N
downward force and a 5 N m moment are applied as indicated. . Using hand
calculations, determine the displacement and slope at all three nodes knowing
the element stiffness matrix is given by
