Very helpful. One thing though, how do you know the relationship result-variable, why is in that order. Ax, Ay, Bx, Bz, Cy, Cz. I mean in the very final answer of the exercise where you solved it by matrix in the calc. NEED ANSWER ASAP PLEASE.

How can AX produce a moment for MY and MZ that makes no sense to me.

I mean, if AX is in the moment of Y and Z how come BX is only in the moment of Z, they're both going the same direction shouldn't BX also be included in the moment of Y by that logic?

I think the only thing missing was the reaction at C
