Problem 4.5-26 The compound beam ABCDE shown in the figure consists of two beams ( AD and DE ) joined by a hinged connection at D . The hinge can transmit a shear force but not a bending moment. The loads on the beam consist of a 4-kN force at the end of a bracket attached at point B and a 2-kN force at the midpoint of beam DE . Draw the shear-force and bending-moment diagrams for this compound beam.
