Discuss the below:
Q: A certain accelerometer consists essentially of a box containing a mass-spring system with a known natural frequency of 1760 Hz. The box is rigidly attached to a surface which is moving according to the equation y = dm sinωft. If the amplitude zm of the motion of the mass relative to the box times a scale factor 2n is used as a measure of the maximum acceleration am = dm ?2f of the vibrating surface, determine the percent error when the frequency of the vibration is 480 Hz.
