A 13.0-ft-long simply supported timber beam carries a 10.3-kip concentrated load at midspan. The cross-sectional dimensions of the timber are shown in the second figure. Assume L=6.5ft,x=2.1ft,a=3.7in.,b=4.2 in., c=0.9in, and d=10in. (a) At section a - a, determine the magnitude of the shear stress τH in the beam at point H. (b) At section a - a, determine the magnitude of the shear stress Tk in the beam at point K. (c) Determine the maximum horizontal shear stress Tmax that occurs in the beam at any location within the 13.0-ft span length. (d) Determine the maximum tension bending stress σmax that occurs in the beam at any location within the 13.0 - ft span length. Answers: (a) TH= psi. (b) τK= psi. (c) Tmax= psi. (d) σmax= psi.
