# Car Oscillation Amplitude: Frequency & Constant Values

• Jamessamuel
In summary, the conversation is about determining the amplitude of a car's vertical oscillations on an oscillating surface, based on a given graph. The amplitude was found to be constant and the discussion also considered the effect of resonance and the clarity of the graph in representing this information.

## Homework Statement

The graph (see image in part 3) illustrates how the amplitude of a car's vertical oscilltions vary withthe frequency of an oscillating surface. I was asked to state the amplitude of the oscillation of the surface. I was told It stayed constant.

Nil

## The Attempt at a Solution

I narrowed it down to x and y. However I cannot justify one over the other.

And you can clearly see where the resonance is. Now, when do you think that the car's amplitude most closely follows the oscillation of the surface - at a very low frequency (for example when the oscillation period is 10 minutes) or at resonance?

The given curve is a bit misleading. The right-hand tail should be asymptotically zero.

Might be, might it not?

Svein has the good clue for you.

Sure, the curve shown doesn't rule it out, but it could be made clearer.

## 1. What is car oscillation amplitude?

Car oscillation amplitude refers to the distance a car moves back and forth from its resting position during a ride. It is a measure of the car's vertical movement.

## 2. How is car oscillation amplitude measured?

Car oscillation amplitude is typically measured using sensors attached to the car's suspension system. These sensors can measure the distance between the car's resting position and its highest and lowest points during a ride, which can then be used to calculate the amplitude.

## 3. What is the relationship between car oscillation amplitude and frequency?

Car oscillation amplitude and frequency have an inverse relationship. This means that as the frequency of oscillation increases, the amplitude decreases, and vice versa.

## 4. What factors can affect car oscillation amplitude?

Several factors can affect car oscillation amplitude, including the weight and distribution of passengers and cargo, the condition of the road, and the suspension system of the car.

## 5. Why is it important to understand car oscillation amplitude?

Understanding car oscillation amplitude is important for ensuring a smooth and comfortable ride. It can also help identify potential issues with a car's suspension system, which can affect the safety and performance of the vehicle.
