Doppler effect and Resonance-relationship?

AI Thread Summary
The discussion centers on the relationship between the Doppler effect and resonance, particularly in the context of the Menar Jonban, a structure that exhibits synchronized shaking. The Doppler effect refers to the change in frequency of a wave in relation to an observer moving relative to the wave source, while resonance involves an increase in amplitude when a system is driven at its natural frequency. Participants clarify that these two concepts, although related to wave phenomena, are distinct and not directly connected. The consensus is that the Doppler effect does not explain the resonance observed in the Menar Jonban. Understanding these differences is crucial for accurately interpreting wave behavior in various contexts.

Doppler effect and Resonance--relationship?

we have a structure called Menar Jonban (i.e. Shaking Minaret-- it's basically a minaret that could be shaken --- literally!..you shake one minaret and the other one shakes too!) ... obviously the best explanation of the phenomenon is resonance .. but someone told me "resonance or Doppler effect" .. what does Doppler got to do with it? ...

I know these concepts are from the same family (kinda!) ... but what's the relationship between the two? ..is my friend mistaken, or can you explain one based on the other? ..


thanks.

I guess it should be Doppler effect.
Doppler effect is shift of frequency of a moving particle/wave.
Resonance is the increase in amplitude.
 


They are not related.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
