An airplane propeller has a mass of 160 kg and has a radius of gyration of 800 mm. Knowing that the propeller rotates at 1600 rpm as the airplane is traveling on a vertical circular path of 600-m radios at 540 km/h, determine the magnitude of the couple exerted by the propeller on its shaft due to the rotation of the airplane.
