There were early attempts in the development of the airplane to use rotating cylinders as airfoils. consider such a cylinder having a diameter of 1 mand a length of 10 m. if this cylinder is rotated at 100 rpm while the plane moves at a speed of 100 km/h through the air at 2 km standard atmosphere, estimate the maximum lift that could be developed, disregarding end effects.
