    Proportionality
AI Thread Summary
The discussion focuses on combining proportionality statements related to R, d, and l. The user starts with known relationships, R∝(1/d²) and R∝l, and proposes R∝(l/d²) as a potential solution. This suggestion is confirmed by another participant, who agrees that it is reasonable. The user expresses satisfaction in completing the assignment but later realizes the problem was more about common sense than physics. The conversation highlights the integration of proportionality in problem-solving.

Homework Statement



Combine the proportionality statements for R and d and R and l to form one statement relating R, d, and l.

Homework Equations



I already know that R∝(1/d squared) and R∝l

The Attempt at a Solution



I thought it was R∝ (l/d squared), but that seems too easy lol.


Please help n_n

If by that you mean Rl/(d2), then it certainly sounds reasonable to me. :approve:
 
So it turns out I was right after all! And I finished the assignment.

...

I just realized now that this wasn't a physics problem at all; just pure common sense ;___;
 
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...
