    Homework Threads
AI Thread Summary
A standout homework thread effectively presents the question with a clear title, complete background, and necessary supporting materials like sources and diagrams. Members who take the time to articulate their thought process and specify the help they need are recognized and appreciated by Homework Helpers. Such well-structured threads not only facilitate better assistance but also reflect the member's effort and clarity of thinking, which can influence hiring decisions in academic and professional settings. The forum encourages more members to adopt these practices to enhance the quality of discussions. Developing these habits early is beneficial for students in their academic and future professional endeavors.

Every now and then, this forum has the rare and satisfying experience of hosting a well presented homework thread - a thread where the member seeking help has chosen a title well, written out the original question completely, provided sources and diagrams if required, explained their background and thought process, as well as described the nature of the help needed. Such threads are a pleasure to read and help out with.

In this sticky, the Homework Helpers recognize, congratulate and thank the members who take the care that is necessary to effectively present their questions and show the effort they have made towards answering them.

The following list of members/threads will be updated as and when noteworthy threads catch the attention of the Homework Helpers. We can only hope that more and more posters follow these examples, and that threads like those below become the norm, rather than the exception.

And the authors of the Best Homework Threads are (recent inductees at the top):

When it comes to hiring someone, we look at how well they handle a problem, and we (and certainly myself) are more inclined to hire a student who shows good effort and presents a problem well, which shows clarity of thinking.

Engineers (and probably many scientists) often have their work audited (reviewed), and they are expected to keep fairly detailed notes of calculations (or lab notes) which 1) express an understanding of the problem, 2) the formulae or theory behind the problem and the solution, 3) origin of the input data, 4) assumptions made, and 5) how the solution is obtained. The sooner a student develops this habit, the better.
 
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...
