The composite beam 𝐴𝐵𝐶𝐷𝐸 shown in the figure consists of two beams (𝐴𝐷 and 𝐷𝐸) joined by a hinged connection at 𝐷. The joint can transmit a shear force but not a bending moment. The loads on the beam consist of a force of 4 𝑘𝑁 at the end of a support fixed at point 𝐵 and a force of 2 𝑘𝑁 at the midpoint of the beam 𝐷𝐸. Draw the shear force and bending moment diagrams for this composite beam.
