To test the validity of aerodynamic assumptions made in the design of the aircraft, its model is being tested in a wind tunnel. The support bracket is connected to a force and moment balance, which is zeroed when there is no airflow. Under test condition sS, the lift L, drag D, and pitching moment MG act as shown. The force balance records the lift, drag, an d a moment Mp. Determine MG in terms of L, D, and Mp.
