Well I have the data for the geomagnetic field but it is in Earth's frame if reference.My magnetorquers are in body frame of reference so if I want to calculate the torque, I need to work in the same frame. Both of them are normal Cartesian coordinates. The are not aligned and the body frame is...

I'm currently doing a student project at uni and I'm trying to design magnetorquers for cubesats.Before I make the prototype I need a simulation of what will happen.The problem is that for my calculations,I need to change the frame of reference of the geomagnetic field.So basically I need to go...

After a long day,we were able to solve the problem and I blame myself for the delay. So in general,the minimum happens when the positive moments are equal to the negative moments (since we're talking about the magnitude of the moment).I came up with the idea when I read the question but I made a...

Homework Statement The question is asking us to minimize the maximum bending moment by changing l3. l1=3(m) l2=6.5(m) l4=12(m) P1=1200(KN) P2=2300(KN) P3=410(KN) and we know that obviously, 6.5<l3<12 Homework EquationsThe Attempt at a Solution We made relevant cuts and acquired the equations...

dispersion, interference in thin films and diffraction by regular gratings!got it...thank you for your help!

So you mean it can be diffraction?can it be Birefringence and diffraction at the same time?I need a theory for this thing!for experiments I have a few ideas but for the theory I have almost nothing!

No no no...I definitely didn't mean scattering,diffraction or any other things...I read that the colors appearing on a CD case is because the light polarizes and then Birefringence happens and some how we see colors...I'm trying to see why Birefringence and polarization gives us colors! and by...

I want to find out that what happens if we polarize a white light which has all of the wavelenghts of 400-700 (nm).Does it divide into colors?What happens to it?
