Problem
Shock absorbers are installed in cars to introduce damping into the suspension. What is the principal reason for adding this damping?
(a) To increase the natural frequency of the suspension so that bumps are hardly felt
(b) To reduce the amplitude at resonance and prevent large oscillations of the car body
(c) To reduce the time period of the suspension so that the car returns to equilibrium faster after a bump
(d) To allow the wheels to bounce freely so that the tyres stay in contact with the road surface at all times
