hello, i struggle with this kind of questions and i don't understand the way of thinking and how to solve this.

in the first picture i don't understand why Moments about point Aare a*F1 because there is the 2 P forces that do moments.?

in the second problem i can't understand why there are 3 forces at B in the left side picture and 2 at the right ?

and the third picture how can i know if this structure is properly constrained or not?

thanks alot
