How to calculate total resistance?

AI Thread Summary
To calculate total resistance, first combine resistances in series and then apply parallel resistance formulas as needed. In the first diagram, the total resistance is found by adding 6 ohms and 1.5 ohms, followed by calculating the total resistance for the parallel arrangement. In the second diagram, the total resistance for the parallel components is calculated first, then 1.5 ohms is added. The discussion confirms that the approach to the calculations is correct. Completing the calculations will yield the final total resistance values.

So am I right?
 
Yes, complete the calculations.

Okay, Thanks!
 
Try cropping the images next time. :-p
 

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...
