AI Thread Summary
Chladni figures are typically formed on vibrating plates through resonance, and the discussion explores whether similar patterns can be created on oscillating plates. The effectiveness of this method depends on the amplitude of oscillation and the dimensions of the plate, specifically the ratio of the plate's height to its size. This ratio must be small for the mathematical assumptions underlying Chladni figures to hold true. Additionally, the size and type of particles used, such as grains versus balls, significantly influence the formation of these patterns. Overall, the inquiry highlights the importance of specific conditions in generating Chladni figures on oscillating plates.

i suppose you've heard of the famous chladni figures, formed on vibrating plates, because of resonance...
well, i just wanted to know if there have been experiments with "oscilating" instead of vibrating plates. do we receive the same waves across the surface, if, let's say we have an amplitude of 15 cm?

You can't answer that without knowing how large the actual plate is. The key point is the ratio of the height of the plate to the the size of the plate. The mathematics of the problem assumes that ratio is small.
 
How about the size of the grains? i suppose it matters a lot if they are not sand, but let's say balls, with a few milimeters diameter
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
