Consider a beam AB supported by an elastic rod BC at point B as shown in Figure 10.16. The beam is subjected to uniform load p(x). Use Young's modulus E for the entire structure and cross-sectional area A and moment of inertial I for the beam and the rod, respectively. Model the beam with a single beam finite element and the rod with a single truss element (considered in Chapter 2). Find the nodal displacements and the stresses in the beam. p(x) A L.
