I'm not a physicist, so I won't argue about the physical topics. I am an economist, though, and here's my 2 cents on the economical subject. You're statement is correct, but not complete. You have to add the risk related to advancing technology and changing economic circumstances and...

Thanks for helping me out!

Homework Statement The problem statement: Bridge of length: 200m Construction can expand horizontally to allow thermic expansion Masses of beams: small in comparison to the car Mass of the car: 1360 kg. The answers: Na= 11,0 kN, Ne= 3,67 kN, Fab = Fde = 7,35 kN, Fac = Fce = 6,37 kN...

You cleared it up. Well: these are the values: V= 2 v Resistance at point B = 22 ohm " " " A = 39 ohm " " " C = 10 ohm " " " E = 100 ohm " " " D = 82 ohm. I put the equations we found in a lineair...

Thanks for helping me. If you define paths like: emf - B.R3 - E.R4 = 0 emf - A.R1 - D.R5 = 0 Can you say the following: for the first loop: R3 and R4 are in series: so I count them together, and use V = I.R to calculate the current in the loop? for the second loop: R1 and R5 are in...

But I haven't got a clue how to fit the emf into these equations. Suppose I define a loop in the upper square, I've got: (clockwise rotation) - A . R1 + C . R2 + B . R3 + ? = 0 And in the lower square I've got: (clockwise rotation) - E . R4 - C . R2 - D . R5 + ? = 0 And if you...

I have a problem solving the following direct current circuit: The Resistor-values are know, as is the ems. The question is to define the current in each part of the circuit. I thougth of solving it with kirchhoff rules, and therefore I defined several currents. (I, A-> E) I set up...
