Multiple thermodynamics problems

AI Thread Summary
The discussion revolves around thermodynamics homework problems, with a request for clearer problem statements due to illegibility in provided images. Participants emphasize the importance of making the content accessible for effective assistance and suggest posting one problem at a time for clarity. There is a concern about relying on only two equations to solve multiple questions, indicating a need for deeper understanding. The original poster expresses uncertainty about their approach and aims to test their knowledge through various problems. Overall, the conversation highlights the need for structured and clear communication in academic forums.

Hi Jason,

Could you translate the problem statement into something typed ? I can read about 85% of the first three pages and the remainder is irritatingly illegible. And on top of that: The picture won't be available after a while, so then this thread loses its worth for PF.

I also find it strange that you should be able to solve so many questions with only two relevant equations :rolleyes:

Where specifically do you need assistance ?

You should bear in mind that a lot of people would like some help; it would be unfair to them if potential helpers spent hours and hours wading through your post. PLease help the helpers help you effectively :smile:
 
It's also recommended that you post one problem per thread. PF is not here to write a solutions manual for all your homework problems.
 
My problem that I'm not sure of what I'm doing, so I took multiple and different problems and tried to solve them to test myself, and to be sure I put them here.

Sorry for not following the template precisely, I don't have access to the internet all the time.

Anyway, I will put the problems one by one and try to discuss them with you:

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...
