Question

2. (10 pts) Two identical smooth cubes are connected together by a 0.10-m diameter smooth circular rod, all made of the same material, as shown. The entire assembly falls vertically through a reservoir of benzene (SG = 0.88, μ 6.51 104 N-s/m2) at a terminal velocity of 2.5 m/s. The drag coefficient for the cubes is 0.81. What is the density of the material composing the cubes and rod? Extra Credit Ipt): Without changing the dimensions of the cubes or rod, what design changes could you make to reduce the drag?Explain 0.35 m
