A motor cycle with its rider, weight 250kg, the centre of gravity of the machine and rider combined being 60cm above the ground level when the machine is standing upright. Each road wheel has a moment of Inertia 8.0kg-m2 and a rolling diameter of 60cm. The engine rotates at 6 times the speed of road wheels and in the same sense The moment of inertia of the rotating parts of the engine is 1.5kg-m2. Evaluate the angle of heel if the unit is traveling at a speed of 15m/sec in a curve of 30m
