Figure 3 shows a cantilevered beam (ABC) with modulus E and moment of inertia I. A distributed load of wo spans 1/3rd of its length. The beam is simply supported at point B. Use Castigliano's theorem to determine the reactions at A and B. You can neglect the shear energy due to bending. A 0.5L 1.5L 0.25L Wo E,I B C
