sophiecentaur :cry::cry::cry:

I really appreciate sophiecentaur, rollingstein and Windadct for helping and asking for more details. I didn't know it can be used to control many types of motors because what I read from my notes is for Synchro. I am actually confused between increasing the resistance or just by controlling the...

Yup, thanks for the clarification :)

What is the criteria to meet for a sensible question? I have my own doubts that's why I'm asking.Please let me know so the next time I won't post a stupid question here.

can you do it by increasing the series resistance?

I am not 100% sure of my answer.

Homework Statement What is the current flow when a diode is connected in series with a resistor and battery.The cathode of the diode indicated as A is connected to the positive battery terminal.The Anode of the diode indicated as B is connected to the one leg of the resistor and the other is...

I would like to extend my sincere thanks to PhantomJay :approve: for taking his time to explained where I gone wrong.

I still don't understand how I got my calculation wrong for moment A Taking positive as +ve Ma+(1200x3)+(700x7)=0 Ma+8500=0 Ma=-8500Nm CCW

But for post #13 I did follow my sign convention consistently and why my answer is still wrong? Can you tell me which part is wrong? Can you tell me what is the correct value for the BMD? Thank you..

So I must follow your orientation as CCW +ve, CW as -ve for all the questions if not I'm wrong? I thought we can set out own orientation but must follow accordingly... And I thought you told me that my Ma should be +ve 8500Nm.. Thank you.

This is the new BMD, but it don't make any sense to me. I thought for BMD you always start at 0 and end at 0. For this BMD, I start at 0 but end at 17240. Whereas for the old BMD, I start and end at 0.

I am really confused on why Moment A is not - 8500Nm CW.. Can you please take a look at post #13 again? I set my orientation as +ve CW

Yes..I already calculated Ra=1900N and based on the SFD and BMD, I have found that Ma=-8500Nm Mb=-2800Nm Mc=0Nm I would like to ask without drawing the BMD, can I calculate each Moment individually?

I would like to ask can I just calculate the moment for each point A,B,C manually without drawing the BMD? As shown in post #10. And what do you mean by "Write your equations of static equilibrium using point A as the reference for the moments." Thank you.
