Question

An accelerometer is measuring a structure as described below:


Damping ratio of accelerometer = 0.65


Highest frequency measured by the accelerometer = 6000 hz


Natural frequency of the accelerometer = 18000 hz


What is the percentage error in the accelerometer at the highest frequency it can measure? (Type in a two-decimal number that represents a percentage)

Answer 1

The percentage error in the accelerometer at the highest frequency it can measure is

$$\epsilon=\frac{0.65\cdot6000}{18000}\cdot100\%=21.66\%.$$
