Measuring Vibration (br0094) - Brüel & Kjær

When we looked at the vibrating tuning fork we consid- ered the amplitude of the wave as the physical displace- ment of the fork ends to either side of the rest position. In addition to Displacement we can also describe the movement of the fork leg in terms of its velocity and its acceleration. The form and period of the vibration remain


1 CHAPTER 17 VIBRATING SYSTEMS 17.1 Introduction A mass m is attached to an elastic spring of force constant k, the other end of which is attached to a fixed point. The spring is supposed to obey Hooke's law, namely that, when it is extended (or compressed) by a distance x from its natural length, the tension (or thrust) in the spring is kx, and the equation of motion is mx&& = − kx.
