Mesh Analysis (2 loops 3 supplies)

AI Thread Summary
The discussion focuses on performing mesh analysis for a circuit with two loops and three voltage supplies. The main challenge is determining the correct voltage drop across each resistor while avoiding duplicate terms for components already accounted for in the analysis. A suggested formula for loop one is provided, emphasizing the importance of only passing through each component once during the analysis. Clarity in the approach is crucial for accurately solving the circuit. Proper execution of these steps will lead to the correct identification of currents and voltage drops.

1.Find the voltage drop across each resistor? (I'll be able to do this after finding out the currents)

I've had a go at the formulas but not sure if they're right I've never done 3 voltage sources before so the middle one is putting me off. Any help with the formulas would be great thanks.

You were doing great until you started to write duplicate or additional terms for components that you'd already passed through on your trips around each loop.

For loop one, for example:

V1 - R1*I1 - R2(I1 - I2) - V2 = 0

That's it. That's all.

The procedure is to "walk" around the loop and examine each component as you come to it. You only pass through each component once!
 
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...
