A road roller has a total mass of 12 tonnes

Example 3.5. A road roller has a total mass of 12 tonnes. The front roller has a mass of 2 tonnes, a radius of gyration of 0.4 m and a diameter of 1.2 m. The rear axle, together with its wheels, has a mass of 2.5 tonnes, a radius of gyration of 0.6 m and a diameter of 1.5 m. Calculate : 1. Kinetic energy of rotation of the wheels and axles at a speed of 9 km/h, 2. Total kinetic energy of road roller, and 3. Braking force required to bring the roller to rest from 9 km/h in 6 m on the level.
