An attempt is made to develop an airplane with two rotating cylinders instead of airfoils to produce vertical lift. Each cylinder has a diameter of ( 2 frac{3}{4} mathrm{~m} ) and length of ( 15 mathrm{~m} ), rotates at ( 750 mathrm{rpm} ), while the plane moves at ( 8.41 mathrm{~m} / mathrm{s} ) through air. Estimate the lift force.
