Atypical world war i biplane fighter has a number of vertical interwing struts and diagonal bracing wires. assume for a given airplane that the total length for the vertical struts (summed together) is 25 ft, and that the struts are cylindrical with a diameter of 2 in. assume also that the total length of the bracing wires is 80 ft, with a cylindrical diameter of 3/32 in. calculate the drag (in pounds) contributed by these struts and bracing wires when the airplane isflying at 165 mi/h at standard sea level. also, calculate the total zero-lift drag for the airplane, for which the total wing area is 230 ft2 and the zero-lift drag coefficient is 0.036. (round the final answers to the nearest whole number.)
