Yeah you're right.. I'll try tonight!

In my idea an output is like my last picture y(Z), when there is nothing after it.

I don't know where to split my diagram to get wm as an output. What are the transfer function useless, etc.

I'll try to simplify my block diagram tonight. Right now, I'm at work.

Well I know how to get transfer function when I got Input and Output. (I only simplify my diagram). But I don't know how to get my transfer function when it is not between input and output. (There's no output..) Like this:

Here is a translation: We want to know position x(t) of mass m with the help of a DC moteur and a gear system. All system elements are shown on picture 2. a) With the use of block diagram (first picture I posted) and parameters (in my last picture), find transfer function of every system...

F(s) is ok. Here is why (this is a list of all the parameter): La = 0.0H Why this table, everything that can help find a solution is here.

I think omega m is wm. Here is mechanical drawing from where my block diagram came. Sorry it is in french. a) should link motor electric supply Vm to speed of shaft in rotation. (Wm) Thanks! JP

Hello guys! 1 & 2: I would like to get some help to take everything in A and find transfer function at B and C. I can't find these answer... 3. I know how to go from b) to c) .. we only multiply by E(s) and B(s). But I can't find b) at first. Thanks so much! JPGraphX

This is my project, it is not a pendulum.

Hi, I would like to calculate the function of a rotating disc that has 2 spring slowing it down. (look at my pictures to understand) Let say I turn my disc 90 degrees clockwise and release it, it is going to oscillate a certain moment than stop. I want to plot that function and to have a...
