So you are telling me to abandon a field because I do not understand one problem? The problem I asked an explanation for is here to help me understand and apply Newton's law. So it is normal that I ask a question about the fundamental laws. Take into consideration that some people are slower...

sorry if I am wasting your time if you do not want to help me properly. Just don't reply. I know that I might be asking stupid questions, but I am making effort to understand the problem. If you do not want to help that is ok.

ok thanks

but why do i need to use that in that problem ?

so that is why the forces equals 0

so if the system is in equilibrium the forces along x and y will always be equal to zero ? How did you know that it is in equilibrium ?

why do you say that it is in equilibrium ? The wind is blowing right ?

From equation 1 ? this T sin q - F = 0 (eq.1) ?

In this problem why do I need to use this formula? F – F12 = m1 a along the x-axis. What does F12=-F21 stand for? And I don't understand when they say to find the magnitude of the forces between the two blocks

I don't understand where F comes from because in the problem there is only the tension of the cord. And I have another question the forces along y-axis always be equal to zero? And why T cos q - m g = 0 equal zero? if it is along the X-axis
