Extracted text: A wood pole of solid circular cross section (d = diameter) is subjected to a triangular distributed horizontal force of peak intensity go = 21 (see the figure). The length of the pole is L = 5 ft, and the allowable stresses in the wood are 2,000 psi in bending and 150 psi in shear. in. 90 Determine the minimum required diameter of the pole based upon (a) the allowable bending stress, and (b) the allowable shear stress. Round your answers to three decimal plases. (a) dmin = in. (b) dmin = in. 100
