(c) Beam AB is made of three planks glued together and is subjected, in its plane of symmetry, to the loading as shown. Knowing that the width of each glued joint is 20 mm, determine the average shearing stress in each joint at section n-n of the beam. The location of the centroid of the section is given in the sketch and the centroidal moment of inertia is known to be l = 8.63 x 10 m². 1.5 KN 1.5 KN n n - 0.4 m 20 mm 80 mm 20 mm 0.2 m 100 mm C -Joint a -20 mm 0.4 m- 68.3 mm Joint b 60 mm- B
