b) The simply supported beam as shown in Figure 2 is made of five planks glued together at A and B. The beam has a length of, L= 4m and carries a concentrated load P = 5 KN. The cross sectional of the beam is shown in Figure 2(b). Given the centroid of the cross section (measured from its base), 9 is 27.73 mm. i) Determine the maximum shear flow at point 4 and B, ii) Determine maximum shearing stress at point A and B, i) If the load, P is increases to 10 kN, discuss whether the joint A and B will break or not. Given the maximum shearing stress for the glhue is 0:45 kPa. (a) 10 mm 40 10 mm 30 mm 30 m 10 mm 10 mm (b) Figure 2
