Question 8259
A properly functioning vehicle suspension serves to:
- Keep the vehicle stationary.
- Keep the vehicle in contact with the ground at all times.
- Transmit the engine's rotation to the wheels.
Show answer and explanation
Correct answer: Keep the vehicle in contact with the ground at all times.
The suspension, with its springs and shock absorbers, absorbs bumps and irregularities in the road surface so the wheels stay in contact with the roadway. This keeps the car stable, improves braking, and makes the ride more comfortable. Securing the car against movement is the parking brake's job, and transferring the engine's rotation to the wheels is the transmission's job. In the image, you can see the yellow spring, the blue shock absorber, and the arm that holds the wheel.
