Click For Summary
The discussion centers on understanding the timing of a buzzer's vibrations in relation to its driving force on a jacket of length L. It highlights the concept of resonance, where the buzzer's vibrations can reinforce the motion of the jacket. Due to energy losses in the swinging cloth, there is a phase lag, meaning the cloth's response is slightly delayed compared to the buzzer's vibrations. This phase lag results in a continuous reinforcement of the driving force. The interaction between the buzzer and the jacket exemplifies the principles of resonance in physical systems.

How do we tell when the buzzer vibrates during the cycle to provide the driving force?

Many thanks!

It's an example of resonance. https://en.wikipedia.org/wiki/Resonance.
Because there are losses in the swinging cloth, it will always be a bit behind the source of vibration (phase lag). As a result, the impetus from the source is reinforcing.

Thank you for your reply @haruspex !
 
If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm, contraction pipe diameter=1.49cm, that is contraction area ratio A1/A2=1.8 a) If water is stationary(pump OFF) and if I drill a hole anywhere at pipe, water will leak out, because pressure(200kPa) inside is higher than atmospheric pressure (101 325Pa). b)If I turn on pump and water start flowing with with v1=10m/s in A1 wider section, from Bernoulli equation I...
