Extracted text: 8.19 Neglecting the effects of fillets and of stress concentrations, deter- mine the smallest permissible diameters of the solid rods AB and BD. Use Tll = 8 ksi. 1200 lb-in. A 120 lb В 8 in. 300 Ib 10 in. Fig. P8.19 and P8.20 8.20 Knowing that rods AB and BD are of diameter 1.25 in. and 1.75 in., respectively, determine the maximum shearing stress in each rod. Neglect the effect of fillets and of stress concentrations.
