Can Chladni Figures Be Formed on Oscillating Plates?

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
 

Thread 'Errors and significant figures'

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...
