A 6.0-m-long simply supported timber beam carries two concentrated loads as shown. The cross-sectional dimensions of the beam are also shown. Assume L= 1.2 m, L2= 2.4m, P = 12 kN, Q = 38 kN, a = 155 mm, b = 170 mm, c = 85 mm, and d = 415 mm. (a) At section a-a, determine the magnitude of the shear stress in the beam at point H. (b) At section a-a, determine the magnitude of the shear stress in the beam at point K. (c) Determine the maximum horizontal shear stress that occurs in the beam at any location within the 6.0-m span length. (d) Determine the maximum conmpression bending stress that occurs in the beam at any location within the 6.0-m span length. A B K b
