Short Answer Questions (2 points each; circle your answer). 1) True or false? The lift generated by the wing is equal to the weight of the airplane. 2) True or false? Integrating the pressure force and shear stress force around a body moving through the air will yield a resultant force acting on the body that can be broken down into the lift force acting perpendicular to the relative wind and the drag force acting parallel to the relative wind. True or false? The drag over a sphere is dominated by form drag, while the drag over an airfoil is dominated by skin friction drag. 4) True or false? A fluid element that splits at the leading edge of an airfoil and travels over and under the airfoil will meet at the trailing edge. 5) True or false? The stall speed of an aircraft decreases with an increase in bank angle. 6) True or false? Vortex generators transfer high momentum air from outside the boundary layer into the boundary layer to help maintain attached flow. 7) True or false? The screens in the settling chamber of the wind tunnel in the laboratory are used to prepare the flow before entering the test section by minimizing the turbulence and straightening the flow. 3) True or false? The hydrostatic equation says that the pressure increase in a fluid is proportional to the distance traveled down in that fluid. 9) True or false? If the Mach number of the flow is 0.5, the equations governing incompressible flow can be used to analyze the flow field about the configuration and yield the correct answer. 10) True or false? Flaps change the chord line and camber of the airfoil and lift and drag are increased . 11) True or false? Parasite drag is any drag on the vehicle that is not producing lift. 12) True or false? The environment for reduced drag on a vehicle requires hot air, high elevation and dry air. 13) True or false? The airspeed for minimum drag yields the best L/D ratio, best glide angle and maximum gliding distance. much rudder. 14) True or false? Overbanking tendency in a turning airplane is caused by the use of too
