  Vehicle Body: A major component of a vehicle is the body, which is attached to the chassis. Earlier generations of vehicles had a simple wooden cover body attached to the horse carriage. Automobiles today are made from metal, providing a more stylish design. The body has the following functions:  In order to provide protection against both weather and collision, a vehicle's body serves the following functions: It protects passengers from wind and weather. For the comfort of the passengers. To provide a stylish (better looking) appearance to the overall vehicle. A requirement from the body is:  Stiffness in torsion To prevent flexing on bad roads, the body of the vehicle should not twist between the front and rear.  The stiffness of the beam The body of the vehicle should be stiff to prevent sagging in the middle to prevent jamming of the doors.  Protection against side impacts The side members and doors of the vehicle should be able to withstand side impact forces in the event of

Front engine rear-wheel drive. Rear engine rear-wheel drive. Front-engine front-wheel drive Four-wheel drive. Articulated vehicle layout. Front engine rear-wheel drive : The drive chain in this layout is as follows: Engine → clutch gearbox universal joint propeller shaft differential rear axle wheels. The following are advantages: Weight distribution in a vehicle (engine weight is on the front axle, passenger weight is on the rear axle). Design with a simple steering mechanism for the front axle. Increased luggage carrying capacity at the rear.  Linkages controlling the engine are short and simple, such as clutches and accelerators. Access to various engine components is easier. Taking full advantage of the natural airstream flowing across the radiator will improve engine cooling. The following are disadvantages its name suggests, this is the most conventional type of layout, and the engine is located in the front of the vehicle, while the drive is transmitted to the rear axle.  Transm

Automobile layout refers to the design of the vehicle as a whole. Various components and assemblies that convert the engine's power to the wheel's power are depicted in the layout. In addition, the layout shows the relative positioning of all drive-related components. The various components, their relative location, and purposes are as follows: Frame        C. Engine        E. Propeller shaft      G. Wheels            Clutch        D. Gearbox      F. Differential           H. Electrical Equipments Frame: The frame is the basic metallic structure on which various other components/assemblies are mounted. It is connected after the engine and transfers power from the engine to the gearbox at the driver's command. At the foot region of the driver's cabin is a pedal that engages and disengages the clutch and drive. Engine: The engine consists of an internal combustion engine that transforms the thermal energy of fuel into mechanical rotary energy. Gearbox: The gearbox is the
