CHAPTER: 1
INTRODUCTION
There are various kinds of forces which act on an automobile vehicle while driving. These forces are responsible for the instability of the vehicle and they also cause rollover of the vehicle if there is more steering angle when it is running at high velocity.
• The types of forces acting on an automobile are given below:
i. Inertial Forces ii. Centrifugal force iii. Centripetal force iv. Acceleration force
v. Braking force vi. Aerodynamic force vii. Traction forces viii. Steering forces

i. Inertial forces:
• Inertia is a property of an object to resist the change in motion. In automobiles inertia is the resistance to change the direction or velocity of a body either at rest or in motion. Further briefly it is related …show more content…

The magnitude of acceleration: The acceleration magnitude is the difference between the initial speed and arrival speed of the vehicle.
b. Mass of vehicle: If the mass of vehicle is less, then load on the vehicle is reduced. So acceleration force is also dependent upon the mass of vehicle.

v. Braking Force:
• This force is caused due to sudden deceleration of vehicle. When sudden brakes are applied on the vehicle, deceleration force is caused on the vehicle which reduces the stability of passengers inside the vehicle.
• The main factors influencing the braking force are:
a. Mechanical Braking: This force is caused when brake is pressed through brake pedal, which slows down the vehicle. It creates a loss of pure energy which is used to move vehicle.
b. Engine braking: Engine braking or compression means shifting to a lower gear to slow down the vehicle. Like mechanical braking, it creates loss of accumulated energy and also causes a force to passengers sitting inside the vehicle. vi. Aerodynamic force:
• This type of force depends on the dynamic pressure acting on a vehicle. This force is proportional to the square of speed. At very low speeds, this force is negligible. At normal highways, this force may contribute a force equivalent to about 0.03 g
