9.5 Repeat Problem 9.1 if the object is a cone (made by ro- tating the equilateral triangle about the horizontal axis through its tip) rather than a triangular bar. 9.5 FOR BOTH 9.1 and 9.5: If symmetry from top to bottom did not exist, and if object was blunted so that the presented area was .2 ft while the characteristic area for lift was 3 ft ft,what would the lift-drag ratio be? 9.1 Assume that water flowing past the equilateral trian- gular bar shown in Fig. P9.1 produces the pressure distributions indicated. Determine the lift and drag on the bar and the cor- responding lift and drag coefficients (based on frontal area). Ne- glect shear forces.
