Multiple Choice Questions (MCQs)
1. What is the main purpose of a shock absorber in a vehicle?
a) Increase road noise
b) Enhance fuel efficiency
c) Smooth out shocks and vibrations
d) Improve tyre grip
Ans: c) Smooth out shocks and vibrations
2. What component is often paired with a shock absorber to providesuspension in a vehicle?
a) Battery
b) Radiator
c) Spring
d) Exhaust pipe
Ans: c) Spring
3. Which of the following factors can affect the life of a shockabsorber?
a) Road conditions
b) Brand of the vehicle
c) Frequent car washing
d) Color of the vehicle
Ans: a) Road conditions
4. What does a jerking movement during the testing of a shockabsorber indicate?
a) Proper functioning
b) Defect in the shock absorber
c) Need for a car wash
d) Low tyre pressure
Ans: b) Defect in the shock absorber
Answer the following questions
1. Describe the uses and applications of shock absorbers.
Ans: Shock absorbers absorb road shocks and vibrations, control springmovement, improve ride comfort, maintain tyre contact with the road, andenhance vehicle stability and handling.
2. State the reasons which affect life span of shock absorbers.
Ans: Poor road conditions, overloading of vehicle, oil leakage, impropermaintenance, corrosion, and continuous driving on rough surfaces affect thelife span of shock absorbers.
3. Describe the procedure for testing of shock absorber afterremoving it from the vehicle.
Ans: Hold the shock absorber vertically, compress it fully by hand, releaseslowly, and observe smooth resistance and return action; any jerking, noise, or oil leakage indicates a faulty shock absorber.
4. Describe the procedure for testing of shock absorber when it ison the vehicle.
Ans: Push the vehicle body downward and release it; if the vehicleoscillates more than once or shows jerky movement, the shock absorber isdefective.
5. What tools and equipment are required for servicing of shockabsorber.
Ans: Spanners, socket set, spring compressor, screwdrivers, lockingclamps, jack and jack stands, and safety equipment.
