AI Thread Summary
To find the coefficient of kinetic friction (µ) for a pulley, the equation F = µN is used, where F is the force overcoming friction and N is the normal force. A mass of 0.019 kg is mentioned, but it is clarified that this mass cannot represent µ itself. The normal force is calculated as 0.20 kg multiplied by 9.8 m/s². Further details about the setup and the full question are needed for accurate guidance. Understanding the relationship between force, mass, and normal force is crucial for determining µ.

How do I find the coefficient of kinetic friction for a pulley?
F=mueN
If a mass of 0.019 kg overcomes the friction in a pulley, is this mue?
Normal force would be 0.20 kg * 9.8?

But it can't be mue, because I am asked to find mue in the question.

Hi sugarntwiligh! :smile:

(have a mu: µ :wink:)

What is the set-up? :confused:

Can you tell us the full question? :smile:
 

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...
