A 15.4-ft-long simply supported timber beam carries a 4.2-kip concentrated load at midspan. The cross-sectional dimensions of the timber are shown in the second figure. Assume L = 7.7 ft, x = 2.6 ft, a = 3.7 in., b = 4.9 in., c = 1.4 in, and d = 18 in. (a) At section a-a, determine the magnitude of the shear stress TH 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 (d) Determine the maximum tension bending stress y x a L P B max that occurs in the beam at any location within the 15.4-ft span length. max that occurs in the beam at any location within the 15.4-ft span length.
