Question
A certain accelerometer consists essentially of a box containing a mass-spring system with a known natural frequency of 2200 Hz. The box is rigidly attached to a surface that is moving according to the equation y= δm sin wf t If the amplitude zm of the motion of the mass relative to the box times a scale factor wn2 is used as a measure of the maximum acceleration am = δmwf2 of the vibrating surface, determine the percent error when the frequency of the vibration is 600 Hz.
