A racing car has a mass of 1000 kg. Each wheel has a mass of 20 kg and a radius of gyration of 0.3 m. The engine rotating parts have a mass of 15 kg and a radius of gyration of 0.1 m. The engine speed is 4 times the wheel speed. If the car takes a turn of 50 m radius at a speed of 108 km/h, calculate the gyroscopic couple.
