Fluid mechanics. Plate pulled within viscous fluid.

AI Thread Summary
The discussion revolves around a homework problem in fluid mechanics involving a plate pulled through a viscous fluid. The individual has successfully addressed the first part of the problem but is struggling with part B, particularly regarding the different distances between the plate and the stationary plates above and below it. They suspect that the shear forces may not be uniform on both sides of the plate, which could be causing discrepancies in their calculations. The participant seeks clarification on their assumptions and any potential errors in their approach. Assistance is requested to resolve these uncertainties.

Homework Equations





The Attempt at a Solution



I think I did the first part right. But I'm unsure about part B. The distance between the plate t is different between the stationary plate above than the distance below the plate to the stationary plate. Computing using the different distances give me a different value. I'm unsure what I'm doing wrong or what assumption is incorrect.

Any help would be appreciated. Thanks. :]

I was thinking maybe the shear isn't the same on both sides of the plate in part b?
 

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'

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...
