030050019 Part 1. Determination of the center of gravity location: The location of center of gravity (CG) is necessary for Calculating the climbing ability (Gradability) Acceleration performance Designing brake systems and springing Vibration considerations Handling and rollover considerations Driving stability investigations Determining mass moment of inertia etc. Low center of gravity is always desirable, as they are associated with fewer driving dynamic problems and increased vehicle performance during cornering and braking, but in practice the design options are relatively restricted. The position of center of gravity is highly dependent on the loading; when the vehicle is loaded the CG changes in both longitudinal and vertical axis. The body lowers when it is loaded, i.e. its center of gravity drops. The center of gravity of the passengers and the luggage is usually higher than that of the body so the end results a higher overall center of gravity. The first step in calculating the individual wheel loads in steady state cornering,
