Obtain the condition for not toppling for a four-wheeler. On what factors does it depend, and in what way? Think about the normal reactions — where are those and how much are those! What is the recommendation on loading the vehicle for not toppling easily? If a vehicle topples while turning, which wheals leave the contact? Why? How does it affect the tyres? What is the recommendation for this?
