Pérez, Mécanique : fondements et applications. The results show that, the vibration of the tube conveying flow contains enough information for us to measure both the density and the flow rate of the fluid flow through the tube. Referring to Programme 5 in particular, be clear at the outset that vibration is a case of variable acceleration.

You will A transducer is described that enables the oscillations of a membrane to be monitored and the signal amplified so that very small vibrations may be used when measuring the eigenfrequencies. You should find that writing the correct equation of motion for a vibrating system will reinforce your understanding of other dynamics problems.
