The compound beam ABCDE shown in figure (a) consists of two beams (AD and DE) joined 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) 3) Determine the maximum shearing stress in the beam. Sketch the stress distribution over the cross section at a section 5 m to the right of point A, 4 kN A B D 2 kN E |-2 m- 2m2 m 2 m. (a) 90 mm 20 mm H 30 mm (b) 40 mm
