Hi, Needed a query for the stability of two-wheelers in general. How can i derive the equations governing its stability. Suppose i am moving on a straight road, the normal reaction is equal to the Weight of the Vehicle and body combined- hence the vehicle doesn't topple. Suppose i steer left/right. what are the equations that govern this steering. What forces, moments are acting during turning and how are they balanced so that the vehicle(2-wheeler) doesn't topple. Thanks!
