by a hinged connection at D. The beam has the cross section shown in figure (b). 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.
1) Determine the maximum bending stress in the beam.
2) Sketch the stress distribution over the cross section at a section 5 m to the right of point
