3 The equation governing the deflection of a beam, w(x), is given by AK23/793 F where p(x) is the distributed force along the beam. For a cantilever beam subjected to an end load and an end moment as shown in Fig. 1 : -EI 3rd*u dx4 --X EI 1 Fig. 1 = p(x) (5) Mov Po (Continued) Find the deflection of the beam using the Galerkin method with the assumed solution w(x) = Cf(x) = C(3x21-x). where, f(x) is a trial function and C is a constant. Also indicate the advantage of the weak formulation. 14
