Question on functions of the chassis

Match the following

Group A ------------------------------------Group B
(1) Short duration load------------------ (A) Beyond design capacity
(2) Impact load--------------------------- (B) While crossing a broken patch
(3) Inertia Load--------------------------- (C) While applying brakes
(4) Static Load---------------------------- (D) Due to collision of vehicle
(5) Over Load----------------------------- (E) Due to chassis parts


a. (1)-(E), (2)-(B), (3)-(D), (4)-(C), (5)-(A)
b. (1)-(E), (2)-(D), (3)-(C), (4)-(B), (5)-(A)
c. (1)-(B), (2)-(D), (3)-(C), (4)-(E), (5)-(A)
d. (1)-(B), (2)-(A), (3)-(D), (4)-(E), (5)-(C)

Correct Answer : c. (1)-(B), (2)-(D), (3)-(C), (4)-(E), (5)-(A)


A vehicle without a body is called as chassis. The name chassis is used to represent the basic structure or frame parts of a vehicle. It is a French term. It is the main component in vehicle on which all the other components of vehicle like steering system, braking system, transmission system, electrical system, body of vehicle etc. are mounted. It is the backbone of the vehicle and also called as carrying unit.

The one of the main functions of the chassis is to support the vehicle against different loads acting on it. There are various loads act on the chassis frame. When a vehicle crosses an broken patch, the load acts and it is a short duration load. In a case of collision of vehicles, for safety purpose, the impact load should be absorbed by the chassis. When brake is applied in a running vehicle, the wheels stops but th body tends to bend forward and produces inertia load on chassis. Static loads are the loads due to chassis parts. And the overload is beyond the capacity of the chassis to absorb those loads.
