A 5-m long simply supported timber beam carries a uniformly distributed load of 12 kN/m, as shown in Figure P9.11a. The cross-sectional dimensions of the beam are shown in Figure P9.11b. (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 5-m span length. (d) Determine the maximum compression bending stress that occurs in the beam at any location within the 5-m span length
