AI Thread Summary
The discussion revolves around applying Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL) to a circuit problem. The user inquires whether they can equate I1 to -I2, indicating a potential misunderstanding of current direction. Respondents confirm that this equation is valid under certain conditions and request the user to provide their equations for further analysis. The conversation emphasizes the importance of correctly applying KVL and KCL in circuit analysis. Overall, the thread highlights the need for clarity in understanding current relationships in electrical circuits.

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...
