Why is the height of point 2 same as point 3?

AI Thread Summary
The discussion centers on the observation that the height of point 2 is the same as point 3 in a turbine setup, attributed to the small height differences within the turbine. It raises the question of whether this equality is an assumption due to the minimal height variations. The conversation also notes that different types of turbines are employed for smaller height differences. Additionally, there is curiosity about the absence of the approximation symbol "≈" in the context. Overall, the dialogue explores the implications of small height differences in turbine design.

The Attempt at a Solution


Is it an assumption because the difference in height is small?

With a setup as shown height differences within the turbine are very small.
For smaller height differences, other types of turbines are used.

I wonder why it didnt use "≈", thank you!
 
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...
