The simply supported beam AB as shown in Figure Q3(a) has a uniform load of intensity, w=15 kN/m acts throughout the entire length of the beam. The cross-section of the beam is shown in Figure Q3(b). Given the second moment of area, INA = 36 x 106 mm“. (a) Determine the shear stress at the top of the hole at section a-a. (b) Determine the maximum shear stress at point M and N based on the maximum shear force. (c) Calculate the absolute maximum shear stress of the beam. 0.6 m 1.8 m a w = 15 kN/m В Figure Q3 (a) 160 Ø30 hole 110 NA * 70 M y = 80 40 N 100 All dimensions in mm
