Question

Why shock absorbers are used in luxury buses

Answer 1

Answer:

The purpose of shock absorbers is to absorb or damp the shocks or unwanted oscillations in the system. Now in luxury busses, one differentiating factor is the level of comfort. Since the roads might have bumps or irregularities, so it is necessary to use shock absorbers in such busses so that the passengers don’t feel the impact of bump and the comfort level is maintained.

Answer 2

Impact time increases which decreases the force.

Explanation:

It is based on Newton's second law of motion.

In the absence of the shock absorbents, the bus would strongly feel the force when it will encounter small hurdles on the uneven road. With shock absorbents, the impact time increases thereby decreasing the force.

Impulse is given by:

$f\Delta t = \Delta p$

where, p is the momentum, f is the force and Δt is the small time interval.

with Δp =constant,

$f\propto \frac{1}{\Delta t}$

Shock absorbents increase the impact time which decreases the force f.
