A motorcycle and rider have a combined mass of 350kg. At another point in its journey, the motorcycle and rider travel at 80 km/h around a left-hand bend of radius 30m. Calculate:
The angular velocity of each wheel, the moment of inertia of each wheel.
The angular momentum of the wheel prior to entering the bend. and the magnitude of the gyroscopic torque produced on the bike as the rider is driving around the bend.
What is the effect and why is it important to calculate the gyroscopic torque produced on the bike as the rider is driving around the bend? How can you enhance this system?
