Ok, I am not an expert in electronics but if you have a circuit with impedances then its automatically an alternating current circuit. In this case I am only able to use complex way to calculate. (Z_complex * I_complex = V_complex) You have apparent power and therefore effective/active power...

Why not? There are many advantages 1. He earns there his own money and is then not dependent on the company. Also after your masters degree in many cases you have to stay up to 3 years there cause of a stupid contract. (maybe you want to change to another company after 1 or 2 years because of...

I have worked as an assembler for 2 years in the domain of mechanical engineering. I mean the job was ok and I earned a lot of money, but even doing such jobs you normally don't need to be a bachelor in engineering. If you chose it because of the money for you masters degree, i would say do...

Are you sure, that you are right with your function G(s) = (T(t)-T0)/V(t)^2. Isn't there any mistake you might have made? G(s) = (T(t)-T0)/V(t)^2 does not make any sense for me G(s) is a LaPlace transformed function can not include T(t), V(t)

I don't know why it does not work with latex I don't know where you exactly got this function, but if you can say that f_{(t)}={\frac{T(t)-T0}{V(t)^2}} Then this way should be correct G_{(s)} = \int^{\infty }_{0} f_{(t)} \cdot e^{(-st)} \, dt f_{(t)}=\frac{1}{K \cdot R} \cdot...

I am not a LaPlace specialist, but maybe I can help, it will take me I think about 10 minutes

your function is e^{(-0.0154 \cdot t)}

Hi Thats an empiric value for diverse steel. For S235JR for example 104. But I looked for it in the internet. If Lambda < Lambda_p, we have to use way of Tetmajer.

hello I have used Inventor, Solidworks, ProE, Creo (replacement to ProE), and at last CATIA V5 R19. I mean its up to you. If you are designing simple devices, machines without too complicated surfaces, so use Inventor or Solidworks. It's easy to learn. You can handle both, designing...

Hello I have a steel shaft which is loaded by a pressure force in axis direction. If I want to calculate the maximum force I have to proof if this is a kink according to Euler or not. For steel E295 there is a Lambda_p = 89 In my case I calculated that Lambda is 125 --> Lk/i --> i =...

NascentOxygen was quicker than me ;) the value for Eo ist \varepsilon_0 = \frac{1}{\mu_0 c_0^{2}} = 8{,}854\,187\,817\,62\ldots \cdot 10^{-12}~\frac{\mathrm{As}}{\mathrm{Vm}}

hey NascentOxygen Thank you very much, you helped a lot.

Hey Thank you for your help Ok, does that mean, that v(t) itself is angular phase shifted by u*sin(wt+beta). Also the same with i(t) --> i*sin(wt+beta) And the addition of phi signalizes that there is an angular difference between u and i? Therefore I can write it more simple as...

Hello I looked for a good forum which I can use for my specific questions. I hope I am right here. English is unfortunately not my first language, but I am working on improving it. So please have understanding for it. I need help in three phase drive technology. I read in my book...
