State the different bodies used in automobiles:   The Automobile bodies are divided in two groups i.e.

According to Chassis design the body can divided into

1.       Conventional Type

2.       Integral Type

3.       Semi- Integral Type

 

According to other usage:

1.       Light vehicle Bodies - cars, jeeps

2.       Heavy vehicle Bodies – Busses, Lorries

3.       Medium vehicle Bodies - Vans, Matadors

Requirements of bodies for various types of vehicle:

The body of the most vehicles should fulfill the following requirements:

1.       The body should be light.

2.       It should have minimum number of components.

3.       It should provide sufficient space for passengers and luggage.

4.       It should withstand vibrations while in motion.

5.       It should offer minimum resistance to air.

6.       It should be cheap and easy in manufacturing.

7.       It should be attractive in shape and colour.

8.       It should have uniformly distributed load.

9.       It should have long fatigue life.

10.   It should provide good vision and ventilation.
