Question

I have recorded the amplitudes at different time moments for the following vibration. Please calculate the root-mean-square amplitude using the following steps.

Answer 1

To calculate the root-mean-square (V_rms) amplitude, square the amplitude, find the mean, and take the square root of the mean.

Step-by-step explanation:

To calculate the root-mean-square (Vrms) amplitude, we need to follow these steps:

1. Square the amplitude: (30 V/m)2 = 900 V2/m2.
2. Find the mean or average of the squared amplitudes: Average = (900 V2/m2) / number of data points.
3. Take the square root of the mean: Vrms = √(average).

Using the recorded amplitudes at different time moments, calculate the root-mean-square amplitude following the steps above.
